Insulation of the house with foam from the inside. Step -by -step recommendations

Are you sick of cold drafts entering your house in the dead of winter? Or maybe you’re sick of paying exorbitant energy costs as a result of ineffective heating? Look no further; installing foam insulation within your home may be the answer you’ve been looking for. We’ll take you step-by-step through the process of using foam insulation to insulate your home from the inside, along with some useful tips to help you create a more comfortable and energy-efficient living space.

Providing your home with insulation is similar to giving it a warm sweater for the winter and a cool shade for the summer. You can build a barrier that helps control the interior temperature of your house and lessen the need for excessive heating or cooling by adding foam insulation from the inside. This not only results in a more comfortable living space but can also cut your energy costs dramatically, saving you money over time.

It’s important to know the different types of foam insulation that are available before beginning the insulation process. Foam with open and closed cells are two popular varieties. Although open-cell foam is less costly and lighter, its insulating capabilities are marginally diminished. Conversely, closed-cell foam is more expensive but denser and offers superior insulation. The kind of foam that works best for you will depend on your needs for insulation and your budget.

It’s time to get the space ready for installation now that you’ve decided on the kind of foam insulation for your house. First, make sure the walls are clean and dry and remove any obstacles. In order for the foam to properly adhere and form a seamless barrier, this step is essential. In order to stop air leaks, make sure to seal any gaps or cracks in the walls. Even the smallest openings can reduce the insulation’s effectiveness.

Now that the preparatory work has been completed, the insulation process can start. Foam insulation is sprayed or injected into the walls using specialized equipment. Once inside the walls, the insulation expands to fill any spaces and form a continuous layer. Be cautious when applying the foam to prevent bulges or uneven surfaces. Do not overfill. You’ll be left with walls that are stronger, more resistant to mold and moisture, and well-insulated after the foam has cured, which usually takes a few hours.

Step Recommendation
1 Assess the condition of your walls and identify any existing moisture issues.
2 Clean the surface of the walls thoroughly to ensure proper adhesion of the foam insulation.
3 Seal any cracks or gaps in the walls to prevent air leakage.
4 Measure and cut the foam insulation panels to fit the walls.
5 Apply adhesive to the back of the foam panels and press them firmly against the walls.
6 Use foam sealant to fill in any gaps between the panels and around windows and doors.
7 Allow the foam insulation to cure completely before covering it with drywall or other finishing materials.

What is penopol?

Penophol is a building material whose primary function is to insulate against heat and sound. It is composed of multiple layers: a pre-foamed polyethylene base, and two foil layers.

Utilized as supplementary and primary thermal insulation material. The coefficient of heat reflection is 96–98%.

Penofol’s primary thermal insulation source will be indoor spaces with allowable heat loss (baths, rooms with installed heat sources). Utilize when developing the "warm floor" system. We have written a separate piece about this and do not, however, recommend it.

Will act as a supplementary layer of insulation when residential and commercial buildings are being integrated with thermal insulation. Foam insulation can be used both externally and internally to warm a house. The range of temperatures is between "-60" and "+100" degrees Celsius.

Penophol discovers that the insulation of the floor, ceiling, walls, basements, roofs, and attics can be applied on a civilian and cleaned scale. It is utilized in air conditioning systems, water heaters, door and window openings, pipelines, and hydraulic and thermal insulation.

It was observed that foam was used to insulate the interior components of the car during assembly.

Types of foam

Foam comes in three primary varieties. Use foil when using it, and don’t use it when it’s not needed. broken through.

Because a foil-analogue has significantly more thermal insulation than a foamed base without foil, the non-folgy is less common. utilized as rugs in bathrooms, sheds, and other domestic spaces. is an antiquated building material.

The classes of foil foam are as follows:

  • class a. The base layer is covered with foil only on one side. Most often used in the process of complex thermal insulation.
  • Class in. The base layer is covered with foil on both sides. Used as insulation of the pipeline, sauna, thermal insulation of industrial equipment.
  • Class p. The base layer on one side is covered with foil, and on the other with adhesive layer. During the installation of a class C fenophol, it is not required to use additional blending products.
  • class r. Similar to class A, but the foil coating has a relief shape. Applicable in the process of creating thermal insulation, consisting of several layers.
  • Alp class. The base layer on one side is covered with foil, and on the other, it is laminated with a film made of polyethylene. Finds use in the manufacture of greenhouses and incubators.
  • NET class. Has the properties of class B, but more elastic.
  • Supernet class. Especially resistant to aggressive external weather conditions.

Advantages and disadvantages

The following are Penophol’s primary benefits:

  1. Low level of permeability of steam. Polypropylene does not miss the evaporation of the couple. The need to use additional vapor barrier measures is absent.
  2. Low thermal conductivity. In terms of the effectiveness of heat conservation in the room, half -centimeter foam is commensurate with mineral wool, at least 1 cm thick.
  3. Moisture resistance. Regardless of installation, Penofol does not absorb moisture.
  4. Endowed with high impenetration of sound. The material of this class is regularly used in order to give the premises soundproofness.
  5. Refractory. In case of fire, the material melts, not burning.
  6. It has a small thickness. From 3 mm. up to 1 cm.
  7. Flexible. Convenient in work.
  8. Lasting.
  9. Does not require complex installation technologies.
  10. Has a small weight, which significantly facilitates transportation and installation.
  11. It has an affordable price.
  12. Easy. Does not create a load on the supporting elements.

The following are the foam’s shortcomings:

  1. In view of the presence in the composition of the foil, it is a conductor of electric current.
  2. Has poor adhesion, as a result of which fastening with glue is impossible. It is necessary to use specialized adhesive tape or brackets.
  3. Low hardness of the material leads to its deformation. Hence, it is not possible to use it for some purposes.

Wall insulation

There are various methods for attaching foam to the wall surface. Specifically: frame (with wooden rails) and frameless (no racks).

There are multiple steps in the frame method. The first step is to fasten wooden rails to the wall at a sixty-centimeter gap. Foam is then fastened to the frame. Afterwards, another frame is made, like drywall, that closes. An air cushion built into the design will prevent heat loss and provide a good internal foam warming option for the walls.

An illustration of foam-insulated wall frames

In this instance, we will investigate the frameless installation technique in greater detail. We’ll require:

  • Class B penolon;
  • pencil;
  • stationery building knife;
  • roulette;
  • putty knife;
  • electric drill;
  • dowels;
  • Metal tape.

Preparing the surface is the first step. The foam needs to be cleared of any unnecessary materials before it can be attached to the wall. To ensure that the electrical wiring components won’t come into contact with the foam when the walls are insulated from the interior, fill in all of the cracks with plaster solution.

Previously, I divided the foam roll into sections according to the wall’s width using an office knife.

We move on to the installation. We secure the foam to the wall’s surface vertically using a mortgage of dowels, washers, and an electric drill. Using a drill, the dowel is placed inside the puck and twisted. In this manner, a foam leaf is fastened to the sheet on both sides, at the top and bottom.

It is required to use metal tape to seal all of the joints once the foam has completely covered the wall. Thus, you cover the whole area.

Floor insulation

Penophol is used as a component of a "warm floor" structure as well as an independent floor surface heater.

We’ll require:

  • pencil for marking;
  • Penophol roll;
  • level;
  • metal tape;
  • dowel;
  • construction stapler and brackets to it;
  • electric drill.

Both times, the floor’s surface is meticulously cleared of any foreign objects, like tiny stones or protruding nails. They may cause the material to be damaged, which will dramatically reduce its ability to provide thermal insulation.

We mark the surface with a laser or regular level. Using a stapler, we secure the material with brackets using a stapler. The foil-covered side needs to be facing outside.

We cover the joint area with metal tape.

Following the completion of the internal foam flooring installation, you can begin constructing the river frame, to which plywood or chipboard sheets will later be affixed.

We’ll walk you through the process of using foam to insulate your home from the inside in this article. For energy efficiency, comfort in your living area, and lower heating costs, insulation is essential. Because it is relatively simple to install and effective, foam insulation is a popular option. We’ll offer detailed instructions that cover everything from getting the space ready for insulation to correctly applying the foam. You can increase your home’s insulation and make it more comfortable and energy-efficient all year round by adhering to these recommendations.

The insulation of the balcony

Foam insulation must be fixed around the entire perimeter of the space, including the floor, walls, and ceiling, in order to raise the temperature on the balcony or loggia.

We’ll require:

  • Penophol roll;
  • industrial stapler and brackets;
  • roulette;
  • metal tape;
  • Chancellery builds a knife;
  • level;
  • mounting foam;
  • wooden rails;
  • dowel;
  • drill;
  • pencil.

After daring them with mounting foam, cracks and gaps must be filled in before work can begin.

We pierce the space between the panel plate and the frame.

Next, the purified surface is packed with a wooden rail frame for the walls and ceiling, to which the foam will later be stapled.

It is required to use metal tape to seal the joints once the foam has been applied to the entire surface.

Foam insulation from the inside can significantly improve comfort and energy efficiency in your house. Step-by-step instructions can help you make sure the procedure is carried out safely and successfully.

First and foremost, it’s critical to evaluate your home’s condition and pinpoint any areas that need insulation. Walls, attics, and crawl spaces may be examples of this. You can identify areas of heat loss and prioritize where to apply foam insulation by carrying out a thorough inspection.

Next, getting ready is essential. The spaces where insulation will be installed should be thoroughly cleaned and cleared. Eliminate any obstructions, dust, or debris that might impede the procedure. To stop the growth of mold or mildew, make sure that all surfaces are dry and free of moisture.

It’s crucial to carefully follow the manufacturer’s instructions when applying foam insulation. Utilize the right tools, such as safety gear and foam guns, to guarantee correct application and protection. Take your time spreading the foam evenly and completely filling in all the cracks and spaces.

Give the insulation enough time to cure and expand after it has been applied. The manufacturer’s guidelines should be consulted for specific recommendations as they may differ based on the type of foam utilized. For a seamless finish, cut away any extra foam and seal any gaps that remain after curing.

Lastly, to guarantee your insulation’s continued efficacy over time, perform routine maintenance and inspections. Keep an eye out for any indications of harm or decay, and take quick action when necessary. You can maximize energy savings and extend the life of your insulation by being proactive.
