The insulation of the foundation on the screw stilts

Insulation is essential for maintaining a warm and energy-efficient home. However, have you given foundation insulation any thought? Insulating the foundation—especially if you have screw stilts—might not be the first thing that comes to mind, but it can have a big impact on your energy costs and comfort level in your house.

Compared to conventional concrete foundations, screw stilts—also referred to as screw piles or helical piles—offer a number of benefits. They’re economical, adaptable, and safe for the environment. However, one of the less well-known advantages of screw stilts is that they work well with insulation, adding an additional degree of defense against moisture intrusion and heat loss.

By putting insulation material around the foundation’s perimeter, you can insulate your home’s interior from the ground by installing a thermal barrier between it and the screw stilts. This lessens the need for excessive heating and cooling by keeping your home cooler in the summer and preventing heat from escaping during the colder months.

Increasing energy efficiency is one of the main justifications for insulating the foundation on screw stilts. Reduce the amount of heat loss through the foundation to lessen your need on heating systems, which will cut down on your energy costs and carbon footprint. Better energy efficiency also results in a more comfortable living space all year long with fewer drafts and cold spots.

However, there are other advantages to insulating the foundation on screw stilts besides energy efficiency. By forming a barrier that stops moisture from penetrating into the foundation and walls, it can also aid in the prevention of moisture-related issues like the growth of mold and mildew. This is particularly crucial in high-humidity or flood-prone areas because moisture intrusion can cause structural damage and problems with indoor air quality.

Creating a decorative base

Technology

How can the pile-screwed foundation be insulated by building a base? There are various stages to the technology:

• The choice of material (the sequence of further actions depends on this decision);
• Creating a frame (what it will be depends on the type of insulation);
• ;
• Work with joints;
• FRIENTS.

Now let’s discuss the selection of the content.

Materials

Since the insulation used in the basement of a screw foundation pile will come into contact with the ground, it must have enough hydrophobic properties. For these uses, extruded polystyrene foam is most frequently employed. The material’s 0.04 W/m2 thermal conductivity is low. Furthermore, there is no vapor permeability in this insulation, so he did not miss the moisture inside the frame. On the other hand, one can discuss a few more choices in the interest of justice.

• Polyurethane foam (PPU);
• Penoizole;
• Foam glass;
• Minvatu with high stiffness.

The latter is rarely utilized, requires steam availability, and offers no unique benefits for use in close proximity to soil.

Polyurethane foam requires a continuous frame, such as one made from the board, because it is sprayed on.

They also employ brick masonry, but this is a component of the frame rather than a heater, which implies something else.

Installation

The development of the frame is the second point under "Technology." If the wall’s frame is made of brick, it is constructed using standard building techniques and is insulated like a brick wall. However, due to its higher cost, this approach is not frequently employed. Most frequently, the ribbon’s frame is constructed.

• The guide is attached to the grillage along the entire length of the wall or joins from several elements;
• The lower guide is attached to the blind area;
• After that, the transverse guides are attached along the length of the plate;
• Sheets of polystyrene foam sit on glue-pen on the inside of the profile;
• A professionalist, facing panels or sheets of CSP are attached from the outside;
• All the cracks between the EPPS slabs are blown by the same foam.

After completing all of these actions, the area beneath the house will be considerably more insulated. Furthermore, the insulated frame will provide wind protection. The wind had been blowing between the piles before that. However, the area needs to be ventilated right now. Consequently, two locations are typically blasted using a grinder, after which a ventilation grill is installed or custom opening doors are created.

Remember this crucial moment during the insulation stage.

Carrying out basic calculations

Their preliminary analysis should be completed before beginning work. The following measurements must be taken in advance in order to get precise calculations based on the thermal insulation layer’s parameters and determine its effective thickness:

• The perimeter of the building
• The area of the room
• Square of living rooms
• The degree of load on the base
• Parameters of the screw piles used
• The number of people living in the building
• Features of the local climate
• The level of freezing of the earth"s surface

The required quantity of thermal insulation material and the layer thickness can only be precisely calculated after taking into consideration all of the previously mentioned factors.

Internal floor insulation on the pile foundation

According to the guidelines provided, floor insulation is completed in phases. The entire space is covered in steam that is laid from the outside. Above the type of polystyrene foam, which is covered in boards, is a heater. A floor like that can serve as the finished ceiling of a basement.

You can use modern moisture insulation membranes for wind and hydraulic protection. Although they fit easily and quickly, the price of multipurpose products may put you off.

Every component of a wooden house raised on stilts is given an antiseptic treatment.

It is crucial to remember to maintain the floor’s vapor barrier. It could be a polyethylene film placed atop a layer of material used for thermal insulation.

There shouldn’t be any spaces left between the individual components when installing thermal and steam insulation. Cold bridges may form as a result of this. In this instance, the underfloor insulation may succumb rapidly while in use. Use reproductive boards, plywood sheets, or wood steering plates—all of which don’t radiate heat—to further insulate the interior space from the cold.

Piece of piece materials

For the basement’s construction, bricks, building blocks (aerated concrete, foam concrete, and Tyudu), and foam glass are appropriate. In the latter instance, the substance itself functions well as a heat insulator.

It is required to construct a reinforced concrete strip foundation beneath the piece materials masonry. For this, dig a trench about 20 cm deep around the outside of the house. The strip foundation is made stepped, taking into account the horizontal surfaces, if the house is situated on a slope to lessen the material intensity of the structure.

Organize the materials into a wall after the concrete grabs. In the case of brick, half a brick’s worth of masonry thickness is sufficient for the base of the small height. A more substantial foundation must be prepared, and walls measuring one and a half bricks in thickness, must be laid out for a complete basement.

Maintaining high-quality waterproofing between the masonry and the basement’s concrete foundation is crucial, as is doing so between the masonry and grillage, the horizontal supports between the piles that support the wooden house’s wall structures. Use roll bitumen material, roofing material, or similar materials, laid in two layers, for waterproofing.

Floor insulation

It’s also important to insulate the floor to maximize the benefits of the foundation’s insulation. Consequently, I’ll explain to you how this process is carried out at the end:

1. First of all, you need to lay the black floor. You can make it in two ways – picking sheets of plywood or other sheet material from below to the lags or below on the lags to fix the rails (draft bars) and lay the sheets on them, as shown in the scheme above;
2. Then the waterproofing film overlapping is laid on the lags and black floor. For greater tightness, the joints should be glued with tape;

Mineral mats are used as floor insulation in the frame house that is elevated.

1. Further, thermal insulation material is laid for waterproofing. It is best to use mineral mats for these purposes. It should be noted that the insulation should fit tightly to the lags so that there are no cold bridges;
2. then another layer of thermal insulation is laid on top of the insulation on top of the insulation.

You can now install boards or other flooring on top of the lag. All these adjustments will ensure that your home’s floor stays toasty throughout the winter.

Technology of insulation

The design that will take the place of the base is the creation of a bunch.

You can take care of the pile-screw foundation’s thermal insulation on your own. Accuracy and high-quality materials are the only prerequisites. The creation of a robust design that will fulfill the basement’s purposes is all that remains of the work. This building is the one that will receive insulation.

The way that work is done is as follows:

1. Waterproofing grillage – jumpers connecting piles into a single structure. This stage is required regardless of the material from which the main structural elements are made. At the junction of the grillage with a wall and piles, roofing ground is laid. Metal parts are smeared with moisture -repellent mastic or liquid rubber. Wooden structures are treated with an antiseptic. Read more about insulation of the foundation of a wooden house here.
2. Creation of a bunch – the very design that will replace the base. It is made of brick, wood or simply created a metal frame, on which facing panels are fixed. The bunch will protect the insulation and space under the house from the wind, rain, snow and other unfavorable phenomena. All further insulation work is carried out from the inside of the partitions.
3. Installation of insulation. Foam, foam, any other moisture -resistant material can act as thermal insulation. The slabs are mounted on glue with thorough insulation of joints. You can use foam glass or aerogeles – these are more modern materials that do not require additional waterproofing. Ideally, it is better to apply polyurethane foam on the entire surface. This will strengthen the structure, provide it with wind and moisture protection. And it will be more difficult for rodents to get through such a barrier.
4. Drinking the basement. From the inside, the bolt is sprinkled with gravel, gravel, earth.

Spray-applied polyurethane foam will work better.

The whole area between the only base and the earth’s surface can be covered in soil in the event of severe financial deprivation. It is simple and inexpensive, but it doesn’t work.

It’s important that you accurately assess your strength before warming the stilt foundation. will need to labor under restricted circumstances. Since the material is mounted from the inside, it is unlikely that there will be insufficient space between the soil and the grillage. Spray-applied polyurethane foam will work better. First of all, you are not required to descend beneath the house on your own. Second, even, seamless thermal insulation is a guarantee with such insulation. We’ll take great care to seal all of the gaps between the structural components.

Among heaters, Ecotermix PPU is regarded as the best. We suggest watching the following video to learn more about attic foundation insulation:

How to insulate the foundation of the house from the inside

Nowadays, mineral wool and polystyrene are the most widely used heaters in our market. Because of its tendency to absorb moisture, mineral wool is regarded as a lower-quality internal foundation insulation material. It needs to be deviced with extra waterproofing when in use. Compared to polystyrene, the relatively new material foam has a higher strength and coefficient of thermal protection, but it costs a lot more.

Expanded clay, a light and warm substance, is applied to the area beneath the grillage after insulation, greatly reducing subterranean blowing. Ordinary land can occasionally be filled in place of expanded clay, though this method’s thermal protection is less effective overall despite being far more financially advantageous.

Waterproofing device

The metal used to make all structural elements may corrode if the necessary precautions for a reliable waterproofing device are not taken. Rot and fungi can harm wooden components.

The life of the building can be greatly impacted by the loss of wood or pile characteristics.

One of the waterproofing materials is placed where the pile elements and grillages come into contact with the structure in order to safeguard it. It might be a layer of roofing material, for instance. Additionally, it must be positioned on the grillage faces that connect to the building’s wall.

After that, an antiseptic is applied to the wooden portions of the foundation and waterproofing mastic is applied to the entire structure.

The next step, the insulation of the foundation, is carried out a week later, once the solutions have finally taken hold.

Waterproofing work

Remember that one step in the thermal insulation arrangement is the waterproofing of the screw foundation. These are done to keep moisture from getting into the space between the grillage and the piles themselves.

In the event that waterproofing is not done, the house’s foundation will not last very long. This is because the wooden parts will start to rot and the metal parts will get covered in corrosion. Such a well-known material as roofing material can be used to stop this. It ought to be positioned where the ends of the piles meet the grillage’s starting point. Additionally, they ought to cover the upper portion of the grillage where it meets the wall.

Additionally, all metal components of a screw foundation must be waterproofed using specialized mastic. Simultaneously, a substance is injected into wooden structures to stop the deterioration process in humid environments. You can begin heating the house’s pile foundations only after these materials have dried.

The strip foundation

Dig a trench all the way to the foundation’s sole first. Its width ranges from 80 to 100 cm because the blind area is also insulated. If the foundation is buried, the first 40 cm of the trench’s depth are being dug into the blind area’s width; you can then widen it to 50 cm to conserve strength.

If the house was constructed a while ago, the concrete may have cracks in it. If the cracks are tiny, they are sealed with a cement and building glue mixture. Larger damage is sealed using mortar made of cement.

The waterproofing process comes next. This is accomplished by applying bitumen mastic to the foundation tape’s surface and then adhering roofing material to it. Overlapping sheets are glued together, and the seams are further sealed with mastic. Additionally, more contemporary rolled materials like self-adhesive roll waterproofing are utilized.

Adhere the insulation after that. While dowels are frequently used to attach foam, it is preferable to use glue or liquid nails because they do not compromise the integrity of the sheets. Watch the video to learn how to use polystyrene foam to insulate the strip foundation:

With liquid foam, the joints between the sheets are discouraged.

Geotextiles are adhered to the insulation after it has been installed. It will lessen the impact of soil erosion on the layer that insulates against heat.

After that, the trench is filled in all the way to the blind area. Under the blind area, a layer of 0.15–0.2 m of sand and small crushed stone is applied, and the pillow is fully compacted. The loads that arise from the shifting of the soil will be shielded from the blind area by this layer. On top is a layer of thick insulation. Because of its resistance to compression loads, the same foam is appropriate. After pouring concrete on top, it may need additional reinforcement in the form of a grid.

Take note! The insulation layer is positioned at the foundation’s sole level in order to lessen the impact of frosty heaping. The best possible combination of foam insulation up to the wall level and insulation for the blind area at the sole level.

The insulation of the basement

You can increase the comfort of the interior space of the premises by insulating the basement of the pile foundation. Building a basement is a prerequisite before using any of the current techniques for warming. The device in the basement is permitted in specific ways. A wall that closes off a row of screw piles can be installed. The distance measured from the blind area to the lower belt of the house binding should match the height of the wall.

A bunch that resembles a fake base can be arranged. It will have an external cladding and be set up on a frame base. Should you opt for the initial approach, the masonry work needs to be done in half of a brick. Since red ceramics are the most resistant to high humidity, those will be the products.

A trench is dug around the building’s perimeter in order to prepare the foundation first. It will be 0.3 meters deep and 0.25 meters wide. Large grains of sand are evenly distributed throughout the bottom. The layer should be ten centimeters thick. The sand mixture and moisturizing are then tamped down.

On such a base, a cage of longitudinal and transverse rods serves as reinforcement, into which the concrete mix is poured. You can start building a brick wall once the concrete solution has hardened and gained strength.

Pile foundation

How can a wooden house on piles have its foundation insulated? In order to create a columnar foundation and a pile, they construct a bolt that resembles a basement and seals the gap between the stoves. This will help to mitigate heat loss to some degree already. In order to properly insulate the pile foundation from heat, you need:

• Arrange a base,
• insulate it from the inside and outside,
• insulate the floor.

Either use plate materials that are fastened to the crate, or construct a thin wall of brick around the outside. In the event that the brick wall option is selected, a low-poured concrete tape measuring 20 cm in thickness must be poured before the wall can be constructed. You can substitute foam blocks or foam glass for the exact ceramic brick if you prefer.

Crucial! Never create space beneath a sealed floor. Ventilation holes measuring ten to fifteen centimeters must be made after the bunch is installed.

They are positioned opposite one another, equally on each side of the house.

A wooden bar or metal profile crate is used to fasten panels or slabs. CSP is one material that you can use as outdoor cladding. Insulated facade panels that serve as both decorative and thermal insulators already exist.

They excavate a shallow trench beneath the casing, fill it with a layer of sand (three to five centimeters), add expanded clay, and then cover the trench with dirt to ensure that the soil and skin do not separate.

The device and deception’s insulation are displayed in the video:

Use to insulate the pile foundation

• Foam polystyrene,
• Styrofoam,
• foamed glass in blocks,
• liquid foam (carbamide foam).

The most popular choices are the first two. Foamed glass is too costly for a private residence, and liquid foams need specialized tools or labor from experts, both of which are expensive. With foam or polystyrene on the exterior, insulating a wooden house’s foundation with your hands is simpler. The primary feature that makes the material unsuitable in this situation is its lack of water absorption. For added stability, you can use extra wooden strips that are screwed to the crate through the foam with self-tapping screws. The foam is glued to the glue pen.

Crucial! It is best to adhere the foam or polystyrene to the guides rather than in between them. Since the thermal conductivity of the tree and its higher metal content is greater than that of the foam, there won’t be any gaps or cold bridges in this instance.

It is possible to heat the pile foundation from the inside or the outside using epx or polystyrene. In the event that this is done outside, the insulation is put in place prior to finishing. The insulation is mounted from the inside if the finish is already affixed to the base, as in the case of central stations or facade panels.

Floor insulation

In a wooden house with a pile foundation, I typically use liquid heaters, polystyrene foam, mineral wool, and basalt cotton wool to warm the floor.

The following steps are taken to complete thermal insulation during the building and flooring process:

1. Make a draft floor on which the insulation will lie.
2. The vapor barrier and windproof layer is first put on the crate.
3. Then put the insulation.
4. Vapor barrier and waterproofing are placed on top.
5. After that, they build a final floor.

At least 10 cm should be the minvata layer. If it becomes necessary to layer cotton, it is done in a checkerboard pattern (so that the seams are not identical). The house’s floor insulation on a pile foundation is seen in the video.

You can use isopan, permamine, polyethylene, and wind-moisture protection film for waterproofing. The least expensive option is polyethylene, but it’s not the greatest.

Crucial! It is imperative that you apply an antiseptic to every wooden floor component in a house built on a pile foundation.

The materials and techniques used for warming the pile are similar to those used for insulating the column foundation.

How to insulate a pile screw foundation with your own hands

The procedure can be broken down into five main steps: sealing a metal structure, creating a frame to secure thermal insulation, installing insulation and, if required, waterproofing film, attaching decorative panels to the house’s base, installing an insulated blind area device around the house’s perimeter, and filling the soil or expanded clay inside the foundation of the building. We’ll talk about these phases in more detail later.

1. Waterproofing of the pile foundation

Complete waterproofing is required regardless of the grillage’s material—wood or metal—to prevent soil moisture from penetrating the structure and causing metal corrosion and tree deterioration. All structural components where thermal insulation will be installed must be covered with roll or liquid waterproofing. Bitumen mastic should be applied to the metal frame and antiseptics should be applied to the tree.

A design that resembles the house’s foundation must be created in order to create a heat-saving cladding between the ground and the facade of the building. Light brickwork can be used to create this design on a shallow foundation. The brick base is lined with panels or siding and insulated from the exterior with foam plates or foam and foam. A beam or some metal guides can be used to make a frame.

2. Making the basement of the house

Picture of the pile foundation’s warming scheme

Pouring a finely arched, reinforced foundation up to 20 cm is required to create a brick base. The red brick base is laid out once the concrete has solidified. For brick masonry, the heat insulation plates are attached externally using glue for polystyrene foam and mounting foam. The pile foundation’s insulated brick masonry is covered in ornamental panels that mimic real stone or brickwork.

The second approach, which uses a metal or beam frame, is less complicated and more affordable. It involves welding or fastening horizontal guides to piles with bolts. Heat-insulating slabs are fixed between the guides; mounting foam should be applied to the joints. Decorative panels or siding are mounted further on the outside guides. Using the heat engineering calculator on our website, you can determine the thickness of the insulation in the basement.

3. Thermal insulation of the basement of the house

PVC panels in a sizable portion of the home’s basement

A screw foundation between the guides should leave a gap of 10–15 mm less than the width of the insulation when there is independent insulation of the mineral wool facade or the house base on the pile. There won’t be any cold bridges because the mineral wool will sit tightly between the guides in this instance. We remind you that mineral wool needs to be sealed with waterproofing and that the proper way to install vapor barrier is on top of the insulation.

The seams between the plates should be soldered with mounting foam when warming the foundation on screw piles made of foam or polystyrene foam. The foam plate should be shielded from rodents and potential mechanical damage if the properties of the foamyplex ensure that the material won’t absorb moisture or experience rodent damage. Vinyl or metal siding can be used to cover the insulation in the basement of the house.

4. Fastening of decorative panels

Fixing the starting profile for siding around the entire perimeter of the house is necessary for a clear view of the basement from below. Siding panels or ornamental PVC panels are then attached, working their way up from the starting profile from the bottom. The insulation on the pile foundation will be shielded from precipitation, mechanical damage, and rodent penetration by this facing material. Remember to additionally waterproof the facade before installing siding.

5. Pouring with soil or expanded clay

Picture. Recognizes in the home’s basement (vent holes)

Soil or expanded clay can be poured into an insulated pile on the inside of a screw foundation to further insulate the house’s subterranean area. To prevent the soil beneath the house from freezing and to minimize heat loss during the heating season, a warm blind area should be set up outside the building. Vents should be installed on the opposing sides of the basement and sealed with gratings to keep out rodents and insects.

The purpose of the ventilation holes is to drain moisture from the house’s subterranean; during the winter, rags should be placed over the holes to keep moisture out. In order to eliminate any potential problems, we have included a video tutorial featuring seasoned builders discussing the topic at hand. This involves independently insulating the foundation of screw piles, bathrooms, or country homes.

Insulation on facing base

In the typical scenario, the cladding’s insulation is arranged as follows:

1. Installation on piles for crate
2. The construction of the crate
3. Facing and insulation fastening

Typically, a wooden board crate is positioned atop screw piles; it is most practical to fasten cladding sheets to these surfaces. This necessitates finding a solution to the wooden element to pipe attachment problem.

Installing the label boards on stacks of unique brackets and a metal profile, to which they are screwed, is a good method. It is possible to install vertical wooden racks with a large pile of piles. Extended sheet materials, like metal or vinyl siding, are typically stored in crates that are arranged in parallel to the ground and have a bar counterpart. Оногда, например, достаточно только вертикальных брусков из облицовки профнастилом.

Installation of the basement insulation crate

Naturally, the insulation must be fixed first in order for facing slabs to protect it from the outside.

Typically, monolithic slabs are used as heaters. The inconvenient aspect of using mineral watches is that they have to be fixed on both sides because of the small height of the base and the challenges associated with working from the inside of the perimeter.

Foam is currently the most widely used material for foundation insulation. Similar to polystyrene foam, it is lightweight, precisely cut, and easy to install. It also has a dense structure. It’s actually polystyrene foam that has been extruded. Although it costs more, it has better thermal insulation qualities than regular foam. Compared to foam (0.038 W/MK), the thermal conductivity of the foam is lower at 0.029 W/MK. The properties of the polystyrene foam with a thickness of 50 mm are entirely replaced by a foam sheet that is 30 mm thick. Unlike more loose foam, the foam also does not miss moisture.

Typical foam leaves

Used extensively for other materials, such as insulation:

• Liquid foamy -sprayed on a continuous crate
• Foamed glass produced in blocks.

Sheet insulation is fastened to the crate using self-tapping screws or adhesive.

Once the insulation plates are fastened, the joints must be sealed to prevent cold bridges. This can be done by using liquid sealant or adhesive tape, depending on which is preferable.

Note that non-sectruded foam performs poorly at low temperatures. Moisture can build up in its pores, and frozen water slowly ruins the material. In this way, low temperatures do not affect extruded foam.

The ventilation of the area beneath the house must be considered when installing the insulation. Pods, or ventilation holes, must be left in place. Furthermore, it is advised to maintain a space of 5-7 centimeters between the earth’s surface and the lower portion of the cladding. To reduce the impact of frosty soil swelling, this is required. This clearance closes with a blind area upon completion.

To further safeguard the insulation from rodents, a tiny metal mesh must be applied from the inside.

Basement explosion on piles

Errors and tips

Probably the biggest error was forgetting that insulation was required after construction. It will be far less successful in this instance, as well as probably more costly and time-consuming. Additionally, there’s a chance that the foundation design will be harmed, which could result in issues with the house’s operation or even its destruction.

It is not necessary to disregard conventional waterproofing even though many heaters are fairly resistant to the effects of water, do not deteriorate from it, and occasionally do not miss at all. The secret to its long-term and secure operation is moisture foundation protection.

Useful tips

• After the completion of the procedure for insulation of the base of the building, it is necessary to withstand at least 7 days to strengthen it. Then you can start installing a waterproofing layer.
• Do not forget about the installation of ventilation. The ventilation holes should be strictly opposite each other with a step of at least 1.5 or 2 m.
• In order to prevent the destruction and shift of the soil, you can not move, move or try to unscrew the pile supports of the foundation. This can lead to a complete destruction of it.
• To strengthen the basement and increase the level of its reliability and fortress, you can lay a layer of reinforcing mesh.
• With a properly carried out procedure, the space inside the base can be used for various household needs (underwear, shed, warehouse, place for storing homework, etc.P.In this case, you can conduct communications in the room. Thus, you get an additional technical floor in your own house.

As you can see, practically everything can use the process for thermal insulation to strengthen the pile base. It’s easy enough for any builder to do. It is not necessary to use specialized technology or pick up extra theoretical knowledge.

How best to insulate the base on stilts

Regulatory indicators and the possibility of utilizing all permissible options must be taken into consideration when selecting the optimal insulation option.

However, one cannot divert attention from the economic impact.

The strip foundation that surrounds the house on stilts can be laid and insulated. It will be a trustworthy choice. The procedure will impact the cost of work, but the rooms will remain cozy and warm. A shallow tape is filled as an option. As a result, you won’t have to pay for labor-intensive tasks, and extra adjustments will keep the house warm.

• Isospan: universal insulation material
• How to make a waterproofing of the basement properly?

Any building material can be used to create piles, and expanded clay can be used to create an underground sleeping area. This is a cheap option that works best in areas where the soil is not very wet, but it is not totally effective.

In actuality, there are numerous options that contribute to a large amount of pile foundation, and none of them make sense. With years of experience building houses on pile foundations, experts have developed their "recipes" and suggest taking into account the following approaches:

• External insulation relative to the perimeter of the building. The method is in demand if the fundamental piles do not rise too much above the ground. The process is enclosed in the construction of the frame on the basement, insulation of the basement and external cladding.
• External insulation by floor. If the house stands on the "complex" soil this option the only. In fact, the floor isolation without basement and .
• Combined insulation. In this version, the basement is mounted outside, and isolation in the basement is also carried out.

Regarding a note. The third version of the performance is better but a bit more involved. High levels of thermal insulation and a reduction in the house’s reliance on cold air are ensured during implementation.

The pile base’s warming scheme.

First things first: waterproofing. Any work related to reducing the temperature load on the building material and the entire house is based on this. The goal of waterproofing is to prevent condensation from forming on stilts, grillage, and other locations where metal parts come into contact with wood. In these situations, bitumen mastic is used. Both the foundation’s column and composition cover every connection.

Whether thermal insulation is needed

In their quest to save as much money as possible on their projects, many builders frequently disregard important precautions like insulation and waterproofing.

You should think more closely about the foundation’s design as you assess whether or not insulation is required.

This kind of basement is actually made up of pillars that are positioned beneath the structure. However, there is still a lot of open space in between each pillar. This acts as a point of accumulation for cold air flows, which lowers the building’s overall thermal conductivity.

It is essential to complete the insulation process without fail in order to prevent this. We discovered why the foundation should be insulated. Let us now examine the work item in greater detail.

The foundation of your house is where energy efficiency and warmth retention begin. Don’t undervalue the significance of insulating your home’s foundation when doing so, particularly if it is constructed on screw stilts. In addition to helping to maintain a comfortable interior temperature, insulating the foundation on screw stilts is essential for preventing heat loss and moisture buildup. This part of your house is frequently neglected when it comes to insulation, but doing so will improve structural stability, lower energy costs, and make your family’s living environment more comfortable.

2 Technology of insulation of pile-screw foundation

After the house’s grillage is covered in waterproof material, the foundation insulation process starts. For moisture protection, special membrane films are used; alternatively, if money is tight, standard roofing material can be used.

Foam insulation for the pile-screw foundation

Waterproofing is provided by the heads of piles next to the grillage, the lower and side portions of the grillage, and the upper part of the grillage, which will support the building’s walls.

You will require the following tools in order to make an insulated false fake by hand:

• Welding machine;
• Concrete mixer;
• Screwdriver as insulation of the base with polystyrene foam;
• Hammer, trowel, spatula, roulette, stationery knife.

2.1 Creation of insulated chicks from brick

Although the first option takes longer, the outcome will be as dependable and long-lasting as possible; in contrast, decorative panels are more prone to damage.

Digging a trench that is a few centimeters wider and deeper than the brick size required is required in order to place a brick base beneath the house’s grillage along the entire building’s perimeter.

Concrete is poured into the trench; once it hardens, it will serve as the base for the brick base that has been constructed. Because of the shallow depth of the concrete, a 10–12 mm diameter reinforcement is required to strengthen the base.

The foundation’s brick base rests on screw piles.

Once the concrete has had time to fully solidify, we start constructing the brick foundation. To make it convenient to install the foam panels on the inside surface of the base, the wall must be positioned in intervals of one to two meters.

Isospan AM requires a specific adhesive composition that doesn’t contain organic solvents in order to securely attach the foamyplex. Ceresit CT83 glue has shown to be a reliable product.

2.2 Creating a basement of decorative panels

It is far simpler to install panel false and troops than to build a brick wall. Such a technology for warming the pile-screw foundation will be robust and dependable if it is set up properly.

Priority one should be given to maintaining the supporting structure that the basement’s panels will be fastened to. This requires welding the guide frame from the metal profile to the piles around the house’s perimeter.

The height to which the house is raised above the soil determines the step of the guides; typically, two to three longitudinal profiles are sufficient. A wooden beam can also be utilized as a frame, but it needs to be treated with an antiseptic to stop wood rot beforehand.

The supporting frame is fastened to the heater slabs, also known as foam or extruded polystyrene. The thickness of the slabs must be chosen so that the decorative panel is attached to the grillage and they do not extend past it.

Wooden frame to which the clock is fastened

Moreover, the adhesive composition is used to install a decorative outline on the house’s grillage.

It is crucial to select the panel’s size so that the lower 4-5 centimeters penetrates the soil (you must first dig a small groove) and the upper portion, which is glued to the grillage, assures a dependable fixation of the structure.

Expanded clay sand must be poured after the soil has been removed to a depth of 10 centimeters from the location where the insulation and gut are in contact with the earth.

Because keramzit has a low thermal conductivity, it prevents the structure from freezing during the colder months, resulting in minimal heat transfer to the pile-screw foundation and floor.

Natural ventilation is required by the technology used to set up an insulated false-fed-pin foundation with vapor barrier isoospan in order to prevent excessively damp air beneath the house, which could cause moisture to condense on the inner surface of the floor and cause a wooden structure to deteriorate.

Venting holes must be made in order to guarantee air circulation. One outlet is sufficient on each side of the house. During the colder months, heat-insulating material or a simple cloth are used to cover the outlets.

2.3 technology for arranging insulated basement on screw piles (video)

Thermal insulation work General information

Membrane film for basement watertightness

After waterproofing the grillage, work on thermal insulation of the bath or house pile base should start. Special materials are used for the waterproofing arrangement, such as roofing material or a membrane type, as seen in the above photo. The top of the foundation pillow, which supports the walls of the house or bathrooms, as well as the side and lower portions of the groter and pile heads that adjoin it, needs to be covered with moisture-resistant material.

In this video, you can observe in detail how to waterproof a screw base’s pile heads and grillage:

You will need to get a set of tools ready before beginning to build a false fiber with your hands. You’ll be useful:

• gas welding machine;
• concrete mixer;
• a screwdriver that will be fixed by the PPS;
• Standard construction work tools.

There are two ways to outfit the insulated base: either build a thin brick wall directly beneath the house or bath pillow, or install pre-made decorative panels on top of the pillow.

The base is on the crate

You can construct the base out of sheet materials to minimize installation time and increase efficiency. Usually, TsBS stoves or ornamental panels—which work well with corrugated board—are utilized for this.

Either wood or metal make up the crate. It is possible to weld metal components to the foundation piles. Bolts are used to fasten wooden components in two different ways:

• The ears under the bolts are welded to piles, bars made of wood are attached to them;
• The basis for horizontal guides serve as vertically located bars attached to the grillage, while the gap should remain between the soil surface and the bars.

Under the future base, they dig a shallow trench (around the entire perimeter) to prevent moisture from penetrating into the sheathing and a wooden crate. The bottom is covered with a 2-3 cm layer of sand and a layer of expanded clay called a tamp. To ensure that there is no space between the soil’s surface and the basement, a layer of earth is poured on top of the expanded clay.

The construction of the fake-fiber

No matter which option is chosen, you must first equip a false folk.

Structure types:

1. Light brick aisle.
2. Breeze from decorative panels.

The initial variant is distinctive. Still, this gives you access to a dependable and long-lasting design.

Concrete must be poured into a small foundation in order to create a brick base. You can find the contact details of construction companies that offer on our website. You can visit the "Low-rise country" house exhibition to have direct conversations with representatives.

The steps involved in building a brick piece beneath strapping are as follows:

1. First, dig a trench around the entire perimeter of its placement with a depth of 20-25 cm. The width is made with a small margin relative to the size of the brick used. Concrete is laid inside the finished trench: taking into account the small deepening of the foundation, it is additionally reinforced with a 10-12 mm thick rods with a thickness of steel rods.
2. After the concrete is completely hardened, you can start brickwork in half a brick. It must be built with segments of 1-2 meters: this will create convenient conditions for internal insulation.

For brick false crings, ceramic brick is the preferred material since it can withstand moisture effects better than silicate. Usually, the ribbon casing is applied to non-poudy soils.

The panels’ border is equipped considerably more quickly. On top of screw piles or during welding, steel guides are installed. The height of the piles’ aboveground portion—typically two to three pieces—determines how much profile is used.

Though it is produced more quickly, the fake people from the panels are not as trustworthy.

Vertical jumpers are fastened on top of the guides to make the subsequent installation of the chosen sheathing easier. Sheathing is made of CSP, siding, decorative panels, or corrugated board. Overhead corners and droppers are used to issue corner plots. The drill is made a little higher above the ground to prevent the damaging effects of frosty weather and wet soil. The damper gap measures five to fifteen centimeters in size. A decorative bar can be used to close it during the finishing process.

Whichever style of false-and-orientation is employed, it needs to have ventilation holes to prevent an excessive build-up of moisture within the interior space. The best places for the holes are on the opposing sides of the structure.

Problems of insulated pile foundations

The best materials for low-rise construction are brownish concrete, steel screws, and continuous cross-section reinforced concrete piles. There are several drawbacks to this kind of foundation, regardless of the pile design, installation technique, or grillage technology.

Drawbacks of a pile foundation

If the pile foundation is not insulated during the winter, serious issues may arise.

• Cold underground. Increased heat loss through the floor in the winter period.
• If the grillage is made of reinforced concrete, then a powerful cold battery is created. In case of interruption in heating, restore normal microclimate in such a room for a very long time (up to several days).
• The danger of freezing of engineering communications laid under the floor.
• Pushing piles that fell into the freezing zone. Piles are a cold conductor. If you do not provide for anti -control measures, metal and concrete supports can cause local fusion.
• Uneven shrinkage under the weight of the house when individual piles get into the reduced density of soil.
• From an aesthetic point of view, the usual pile foundation is a purely utilitarian design solution that requires decoration.
• The void under the house, blown by the winds, is quickly littered and periodically requires time to restore order under home.

Why are discrete piles pushed aside, creating an environment where the grillage plane is violated? One of the most frequent causes is the uneven moisture content of the soil, which is higher in the corners and around the edges than in the center. This ultimately results in an uneven freezing depth. Furthermore, the specific expansion during fusion is contingent upon the humidity percentage.

Four out of the seven issues on the list can be resolved with a good thermal insulation device and are directly related to the effects of the cold.

The use of polystyrene foam

In most situations, using materials like extruded polystyrene foam is necessary for thermal insulation of foundations. Its unique qualities include superior noise reduction and thermal insulation, making it a top choice for this kind of work. Because the material sheet is only roughly 3 centimeters thick, internal space is preserved and the base is filled.

The following guidelines need to be adhered to when warming using polystyrene foam:

• If the wall is made of concrete, or brick, it should initially eliminate all cracks on it. For better holding sheets on the foundation, it should be treated using a primer.
• Using special glue, sheets of polystyrene foam must first be glued on the inside of the basement. In some cases, they should additionally be fixed with special umbrellas in the form of dowels. This will help prevent deformation of the material sheets.
• The joints of sheets of polystyrene foam should also be treated with glue. This will prevent gaps through which cold air can enter in a pile screw foundation.
• If the house is wooden, it is best to insulate a two -layer.
• A metal mesh should stick on the sheets on top. She will help prevent the creation of holes in them with rats and various insects.
• Under a wooden house, sometimes blowing can occur even in cases of using polystyrene foam. Therefore, from the inside, soil or expanded clay should be sprinkled to the structure.

The house’s basement can be equipped with such thermal insulation to keep it as cozy as possible during the winter.

Additional recommendations on the choice of insulation

Newbies in the craft world frequently have questions about mineral wool versus foam insulation. The first choice has benefits and drawbacks. It is important to identify non-combustibility, chemical resistance, the material’s ease of bending at angles, temperature resistance, high sound indicators, and thermal insulation among the benefits.

But there are drawbacks to this kind of solution. Among the following, it is important to note:

• sagging;
• moisture absorption;
• carcinogenicity of formaldehyde resins;
• inconvenience of installation;
• reducing the efficiency of thermal insulation over time.

When deciding whether to use mineral wool or polystyrene for insulation, keep in mind that while using the first option is feasible, it does require careful installation, a barrier to keep the material out of the room, and appropriate waterproofing.

Stages of insulation

1. Waterproofing grillage and pile racks.
2. A frame is assembled – a design that replaces the base and serves as the basis for decoration.
3. Installation of decorative finishing material on the basis.
4. Installation of insulation from the inside of the entire structure, elimination of cracks and intervals between sheets.
5. Drinking with expanded clay, crushed stone or soil of the basement, to strengthen it.

Installation of the heat insulator

Take note! This is a cheap, accessible, but inefficient method. This will only result in a partial sealing of the space, eliminating drafts and slightly warming the floors within the house, but you won’t be able to wait for the desired outcome.

Consequently, it is preferable to buy a material with good indicators at a low cost.

1. Foam or its analogues have all these qualities. Thermal insulation is laid from the bottom of the grillage to the first floor of the house. It should be noted that between waterproofing and thermal insulation work should be a gap of about a week. This is necessary so that glue or mastic is completely dry.

Siding being ground in the basement.

1. The next, last step, can be considered final finishing work. After all, the insulation must be protected not only inside, but also outside, and the decoration will also carry a decorative function. Anyone who is familiar with construction, and knows how to insulate the foundation on screw piles, will advise you a lot of materials suitable for these purposes.

Conventional profiled sheet is the most basic and least expensive finishing material. However, it lacks sufficient appeal; as such, if you have the chance, you should purchase equivalents. Additionally, there is a wide range of facade materials available today (see the article Insulating Facades with Foam: We Create External Thermal Insulation with Little Time and Money).

It could be facade panels, decorative brick, stone, or their imitation, or tiles of different shapes, sizes, and colors. They frequently insulate balconies, other kinds of external walls, and loggias from below.

The methods of insulation of the basement

Foam blowout is the simplest option.

Start with foamed glass and think about how to insulate a screw foundation using each of the materials that are presented individually. It is produced in fairly strong blocks, as we have already mentioned, and you must work with regular bricks to work with them. Consequently, you will require a strip foundation if you choose to use the foam glass. Foam-glass bases are highly universal and can be finished to one’s liking.

Since the insulation of the house on the pile screw foundation is the same for both types of polystyrene foam, we will discuss them together. You should first choose which side of the crate the sheets will be attached to:

If the work is to be done outside, it should be done prior to the slabs’ final TSPs being fixed. After that, they are fastened to the crate through the foam, where insulation sheets and finishes come into contact. Insulation is typically applied in phases, so the foam sheets must be fixed from the inside. Even though the second option is simpler to execute, in this instance, it is preferable to do this on the crate rather than in between the guides. Because the thermal conductivity of wooden beams is significantly higher than that of polystyrene foam, there will be a venturezor in the first place and no cold bridges.

The foam, which resembles mounting foam, is adhered to the glue pen, and the joints are naturally sealed using the same foam. As there are only two mounted points, you have the option to add more fixation. You can fasten the thin wooden rail on top of the foam, along the guides. Black self-tapping screws are used to secure it inside the crate through the foam. Everything will firmly hold on, even with just one glue, and the insulation won’t move once the racks are fixed.

The simplest method is to use liquid foam to inflate the base’s inner surface.

He doesn’t need to finish after that. The sheets’ penosol cannot be used because of their extreme fragility. It should be mentioned that you cannot expect a good outcome even if the base is perfectly insulated but the house floor is not. Use mineral wool, which is placed on the crate, to accomplish this. Screw piles form the foundation of the house, upon which the crate is fixed. How to stymie floor insulation:

• A hydraulic boar is laid on the crate – dense polyethylene is quite suitable, not necessarily membranes;
• Mineral wool is laid on top;
• A membrane that passes steam lies between the cotton and the draft floor.

Keep in mind that steam should exit the insulation and enter the room, not the other way around. There should be at least 10 cm of cotton wool.

When laying multiple layers, care must be taken to ensure that the joints do not line up. This will ensure that there is no chance of cold air entering the house.

Materials

Because there is such a wide variety of insulation materials available, you can choose the one that best suits your needs both financially and structurally.

The naturalness or non-naturalness, cost, insulation effectiveness, weight-occupied volume, durability, environmental friendliness, and ease of installation all vary amongst materials.

Among the most widely used synthetic materials are:

• Styrofoam;
• foamopolisterol;
• mineral wool;
• Penophol;
• polyurethane foam;

Foam (impressive polystyrene foam)

Advantages:

1. High indicators of heat and waterproofing.
2. Very lightweight (up to 90% of the foam plate occupies air).
3. Durability.
4. Simplicity of installation.
5. Insensitivity to temperature extremes.
6. Very low price.

Minuses:

1. Combustibility, and the combustion process is accompanied by the release of toxic substances.
2. The ease of mechanical damage.
3. Instability to ultraviolet radiation, aggressive chemical elements and most paint materials.
4. Low air permeability, t.e. The insulated structure will not breathe at all. However, for the foundation this is a small drawback.

Extruded polystyrene foam (technoplex or foam)

The material has a chemical makeup similar to foam, but it has most of the benefits of foam without most of the drawbacks.

Benefits

1. Nice,.
2. Chemical impact.
3. Strength.

Drawbacks:

Mineral wool

Similar insulations made of cottage wool materials, such as glass, blast furnace, or mountain melt, fall under this category.

Advantages:

1. Nice.
2. Temperature drops.
3. Resistance to chemicals.
4. High rates of heat and sound insulation.
5. The convenience of material when enveloping angles and bumps.

Minuses:

1. Sagging.
2. Reducing the efficiency of thermal insulation over time.
3. Moisture absorption (respectively, beating rot, and at very negative temperatures – freezing).
4. The inconvenience of installation (applies to glass wool in which glasses of glass easily fly away everywhere).
5. Carcinogenicity of formaldehyde resins that fasten small particles in the material.

Of course, it is possible to insulate the foundation with mineral wool, but doing so safely during installation, using appropriate waterproofing techniques, and separating the material from the room are all necessary.

Penophol

Is a material for combined film rolls that just came out on the market.

Advantages:

1. Good heat insulation.
2. Moisture resistance.
3. Ease of installation (the material has an adhesive base).

Drawbacks:

1. High price.
2. Poor breathability.

Poliuretan foam

This synthetic material has a foamy texture and is produced in slabs that are ready for installation or in cylinders that can be sprayed.

Advantages:

1. Convenience in installation.
2. Strength.
3. High thermal insulation.

The sprayed option offers several benefits.

1. The ability to vary the thickness of the insulation.
2. High adhesion (adhesion), which allows you to apply the insulation on almost any other materials.
3. Lack of seams, which further increases the thermal insulation of the room.

Minuses:

Natural heaters

Building bundle

Although natural materials are typically used for wooden structures, such as houses, cottages, and buildings, there is no reason why they cannot also be used for the insulation of concrete and metal pile foundations.

Principal kinds

• sawdust;
• tow;
• plywood;
• sheets of chipboard/fiberboard;

Advantages:

1. Environmental friendliness.
2. Lack of harmful discharge during operation.
3. Air permeability.

Minuses:

1. Combustibility.
2. The smaller durability in comparison with synthetic materials.
3. Assignment of dampness, rotting.
4. A favorable environment for insects and rodents.

Good waterproofing, impregnations that increase moisture resistance and render materials inedible and harmful to animals, or the use of heated rooms indoors can, however, eliminate the majority of the disadvantages.

Warming protection from moisture

The foundation’s waterproofing.

There will undoubtedly be some water in the soil even in the construction region’s dry climate. We obtain a continuous water effect on the structure by adding to this condensate, which happens at least at any significant temperature changes.

Furthermore, even the most resilient materials—the foundation itself as well as the insulation—can be destroyed by prolonged exposure.

Materials for coating, spraying, rolling, and leaf application are used in waterproofing.

Together, they will be even more potent:

1. Rolled materials are laid over 10-15 cm, the joints are melted with a burner or coated .
2. Coating and sprayed species are applied to a previously thoroughly cleaned surface with a layer with the necessary thickness.
3. Sheet waterproofing materials are firmly attached to the joint. The seams are sealed with any sprayed or coating tool.

Materials Needed	Process Description
Insulation boards (e.g., extruded polystyrene)	Cut insulation boards to fit between screw stilts and foundation.
Adhesive	Apply adhesive to the surface of the foundation.
Attach Insulation Boards	Press insulation boards onto the adhesive, ensuring a secure bond.
Vapor Barrier (optional)	Install a vapor barrier over the insulation boards to prevent moisture penetration.

Insulating your home’s foundation with screw stilts can significantly improve comfort and energy efficiency. In addition to preventing heat loss, a barrier between your house and the ground keeps moisture out, both of which are essential for preserving a healthy indoor environment.

The versatility of insulating the foundation on screw stilts is one of its main advantages. This technique is appropriate for homes in a variety of geographical locations because it performs well in a range of soil types and temperatures. Adequate insulation can aid in controlling indoor temperatures, alleviating the burden on your HVAC system, regardless of whether you experience bitterly cold winters or scorching summers.

Furthermore, insulating the foundation with screw stilts can result in significant long-term cost savings. You’ll save money on heating during the winter by reducing heat loss through the ground. Furthermore, a well-insulated foundation can help lower interior humidity levels, which lowers the likelihood of mold growth and other moisture-related problems and can save you money on maintenance and repairs.

This approach’s relatively simple installation procedure is another benefit. Insulating on screw stilts can frequently be completed with the least amount of disturbance to your property, in contrast to traditional foundation insulation techniques that might call for substantial excavation or construction work. Homeowners can benefit from a more energy-efficient home sooner rather than later because this will save them time and hassle.

In order to increase comfort, energy efficiency, and indoor air quality, any homeowner would be wise to invest in insulating the foundation on screw stilts. By being proactive, you not only lessen your impact on the environment but also build a more sustainable and comfortable living space that will benefit you and your family for years to come.
