How the installation of a system made of stitched polyethylene is carried out – the price of the issue

Reducing energy expenses and preserving a comfortable living space depend on having your home adequately insulated. The installation of a stitched polyethylene system is one popular and effective method. This creative method helps control indoor temperature and improves energy efficiency, which will ultimately save you money over time.

However, how precisely is this system installed, and what aspects go into its cost? For homeowners thinking about using this insulation solution, it is crucial to comprehend the procedure and the related expenses. In this post, we’ll examine the various factors that affect a stitched polyethylene system’s overall cost and go through the step-by-step installation procedure.

The first step in installing a stitched polyethylene system is to determine how much insulation your house actually needs. A qualified installer will check the amount of insulation that is currently in place, locate any areas where heat loss or air leakage occurs, and decide where the polyethylene sheets will work best. In order to guarantee optimal performance and energy savings, this preliminary assessment is essential.

After the evaluation is finished, the installation procedure can start. Preparing the surfaces on which the polyethylene sheets will be applied is usually the first step. This can entail clearing the walls or attic area of any debris or obstructions that might interfere with the insulation’s ability to adhere.

Subsequently, the polyethylene sheets undergo meticulous measurement and cutting to precisely fit the precise measurements of your residence. Afterwards, using specialist adhesive or mechanical fasteners, these sheets are firmly fixed to the walls, ceilings, or floors, creating a tight seal that reduces heat loss and air infiltration.

To reach the appropriate degree of insulation, more polyethylene layers might be added as the installation goes on. By further enhancing the system’s thermal performance, this layering technique raises the standard of comfort and energy efficiency in the house.

It’s crucial to collaborate with knowledgeable experts who have the experience necessary to guarantee proper installation throughout the installation process. For many homeowners, a stitched polyethylene system is a worthwhile investment, even though the initial cost may be higher than with traditional insulation methods because of the long-term energy savings and comfort benefits.

In conclusion, installing a stitched polyethylene system provides a practical and cost-effective way to raise the insulation level in your house. Homeowners can improve their living space and save energy costs by making educated decisions by knowing the installation procedure and the variables that affect cost.

Features of pipes made of stitched polyethylene

Since woven polyethylene has such high quality, it is frequently utilized in heating and water supply systems. Its name derives from the techniques used to join molecules, which create strong bonds during processing. Polyethylene is added to peroxidal stitching (PE-XA) after it has been heated.

The two steps of the strong-sum method (PE-XB) are as follows: first, a silan and catalyst mixture is added; next, the material is hydrated, or saturated with more moisture. Electron bombardment (PE-XC), which is essentially radiation irradiation, is the less common technique. Nitrogen stitching (PE-XD), the final option, is hardly ever utilized because of the technology’s complexity.

Any of the techniques modifies the molecular structure of polyethylene. Individual hydrogen atoms break off in the molecules’ links, and the resulting free relationship is used to join different chains together. Thus, the term "stitched."

About 90% of the molecules in PE-XA products are fastened, and the pipes have more elasticity.

About 80% of the fastening is provided by PE-XB, which is less elastic but just as strong as the first case’s material.

PE-XC: There are fewer ties—roughly 60%—and polyethylene is prone to creases, which can only be removed with couplings.

Although PE-XD yields a useful result of roughly 70%, the technology is the most expensive and complex of all.

Advantages

PE-XA and PE-XB are the two most widely used material types. The first is made with peroxide (peroxidal stitching), and the second is silica-added Silanova. While each type of polyethylene is beneficial in its own right, there are some differences between them in terms of strength, flexibility, and other factors that need to be considered before installation.

Overall benefits of polyethylene that has been stitched (PEX):

  1. Saves operational qualities at temperatures from 0 to 95 ºС, that is, suitable for heating and water supply pipelines.
  2. Withstands large pressure drops – up to 25 bar (24.7 atmospheres).
  3. Racks to corrosion, but at the same time, when in contact with oxygen, it quickly loses some of its qualities.
  4. Resistant to aggressive chemicals, this allows you to get rid of blockages in pipes using household chemicals.
  5. Elastic and flexible. When healing, it quickly restores its original form. It is easily rounded, which is especially true when installing warm floors.
  6. Has low adhesion, which avoids raids on the walls of the pipes.
  7. Absorbs noise.
  8. It has a little weight.
  9. Long service life. Often the manufacturer indicates the warranty period of 10 years and the operating time – up to 50 years. These two concepts should be distinguished.

The maximum positive parameters are indicated, which is important to note. Depending on the intended use, some stitching styles may have fewer indicators. Pipes used for cold water supply, for instance, have less thermal properties than products used to connect radiators. When making a purchase, the surface provides information about the material’s qualities, enabling you to make an informed decision.

Flaws

Production of PEX is highly expensive, and in some cases it becomes less competitive with other materials.

  1. PEX is not available in large diameters, so PN pipes are used for sewage.
  2. Sensitivity to sun and oxygen.
  3. Some of the varieties are covered with a rather fragile protective layer, there is a risk of damaging it, for example, during transportation.

Types of pipes

The range of applications for a given material is determined by its various properties. Manufacturers provide a variety of pipes designed for various system types.

Universal

Universal products are those that can be used to install heating and water supply systems, as well as to set up a heated floor. These pipes are flexible and able to tolerate the necessary variations in pressure and temperature, making them suitable for use in any kind of system.

The suitability of universal pipes for the transportation of drinking water is attested to by conformance certificates. The carrier may only be utilized for technical purposes, based on the lack of such a document.

Specialized

Specialized products are those meant for any part of the system, such as sewage or cold water supply exclusively. Nearly the same material is used in the production of these pipes, although there may be variations in the quantity of layers, wall thickness, and aluminum layer presence.

Methods of connecting pipes of the heating system

Many connection types are frequently used during system installation; some are intended for use in closed spaces, while others can be used in open pipelines.

There are three primary methods.

  • pressing;
  • compression;
  • welding.

Pressure fitting

Pressing fittings are very easy to install, but special tools are needed. The component is made up of a sleeve and coupling. The connection has the benefit of not requiring a sealing ring like in a compression version. The pipe expands with the tool’s assistance to a size that lets you insert the coupling, and then you pull the sleeve over it. The fitting components deteriorate with time and need to be replaced.

Puffing fitting

Gaskets, seals, a crimp ring, a coupling, and a nut make up a compression fitting. Plus, the connection is really easy to make. The coupling fittings are placed inside the pipe, a ring is placed on top, and a nut is tightened.

To establish this kind of connection, two divorce keys are sufficient. Such a fitting is serviceable, that is, collapsible, even though it necessitates a fairly regular preventive examination and seal replacement. It can always be taken out, swapped out, or used somewhere else.

Electric welding fitting

Domestic welding is relatively uncommon because the necessary equipment is costly and the process itself calls for a high level of expertise. The idea is as follows: metal components are inserted into the polyethylene clutch and heated by the current flowing through them, melting the coupling’s essential constructive element. A dependable and robust spike forms upon cooling.

In the quest for a cozy and energy-efficient home, the installation of a stitched polyethylene system emerges as a cost-effective solution. This method involves strategically placing layers of polyethylene sheets to insulate and protect the house from heat loss. The process typically begins with a thorough assessment of the property"s insulation needs, followed by the precise measurement and cutting of the polyethylene sheets to fit the designated areas. Next comes the installation phase, where the sheets are carefully secured in place using specialized fasteners or adhesives. This system not only helps regulate indoor temperatures but also acts as a barrier against moisture and drafts, enhancing overall comfort while potentially reducing heating costs. Despite its effectiveness, the price of implementing such a system varies depending on factors like the size of the property, the quality of materials used, and labor costs. However, considering its long-term benefits in terms of energy savings and improved comfort levels, the investment in a stitched polyethylene system proves to be a worthwhile endeavor for homeowners aiming to enhance the heating and insulation of their homes.

Installation nuances and rules for connecting to the radiator

Remember that the PEX pipes at the supply section are made to function in temperatures as high as 95 degrees, but coolant with a maximum temperature of 120 degrees can be supplied to the heating system in the event that thermoregulation is not possible. It is also advisable that you familiarize yourself with the conditions of use of SNiPs, which frequently forbid the use of polyethylene pipes in central heating systems.

Adherence to the temperature regime and the lack of abrupt pressure drops are crucial for plastic. Initially, the radiator is fitted with ball valves, which are connected by G-shaped metal tubes that serve as adapters.

DIY system assembly

It is quite possible to collect a heating and water supply system on your own. Naturally, a specialist’s experience won’t get in the way, but success is definitely possible if it’s desired. Currently, assembly is the process of joining various system components together with appropriate connections. Press and compression elements are typically used when utilizing PEX, and they are fairly simple to assemble.

Necessary tools and materials

For installation, a pipeline is required, but a standard metal saw will work too. The most important thing is to make sure the incision is made precisely perpendicularly and to carefully smooth and burr-free the edges.

To work with compression and press fittings, you’ll need the following tools:

  • expander;
  • press vice;
  • Divorce (wrap) keys.

Pipes, adapters, and fittings are needed for the materials, and each case may require a different set of equipment. Whether additional conclusions are required depends on whether the pipes will be connected from the floor or the wall.

The components consist of:

  • block of ball valves or a lower connection node;
  • G- or T-shaped connecting tubes of stainless steel or copper;
  • sets of threaded -assembled joints;
  • Pressure sleeves.

In order to prevent sagging and distortions, fixing gutters and clamps are used to fasten any long-term open areas. Compensators can be used to prevent deformations brought on by temperature variations.

Rehau’s manufacturer offers specialized lines made especially for heating in addition to universal lines. Here, the matching fitting is additionally marked. For instance, the fitting for Rautitan Pink pipes, which have a pink hue, has markings in the same color.

Preparation

The radiator must be marked out in advance, and fasteners must be used for installation. It must also be cut to the appropriate length for the connecting components and the straight pipe for the coolant supply and output.

Laying stitched polyethylene for heating and installing it in the screed are examples of preliminary work. Installing radiators when the floor is ready is preferable.

This video demonstrates how to install a radiator on stitched polyethylene and how to install fittings on pipes.

Connection by compensure fitting

A couple of divorce or wretches are used to attach the compression fitting. Likewise, ball valves connect. There is only one design difference in the part.

A squeezing ring is first placed on the pipe during installation, followed by the nut that the coupling mile is inserted into. The cang ring is pressed onto the element’s unique thread by means of a screwed fastening.

Compression fitting is also used for the lower connection unit node with the radiator and connecting metal tube.

Pressure fitting

The pressing fitting method can be used to mount the heating system and connecting tube. A fitting with a worn-out sleeve is placed into an extended pipe. Here, the sleeve is positioned above the framework.

Electric welding connection

Using this technique, the welding machine is connected to specific terminals on an electric welding coupling. Strong adhesion results from the terminals’ supply to the terminals, warming the plastic. The technology is very rare in private housing construction because it is thought to be very high-quality but too expensive.

Recommendations for operation

Compression fitting has drawbacks despite being serviceable, or detachable. In order to prevent the fitting from being used in closed systems, such a connection must be controlled for subtexts at least once a month during the first six months of operation. Tightening the nut and, in certain situations, replacing the seals are required when leaks are detected. Press fitting is used in screeds, walls, and similar closed systems.

Controlling radiator compounds is also essential. Leaks or pipe bloating may occur if the system is supplied with a heat exchanger that has been overheated. Plastic can only tolerate high temperatures for a limited amount of time; metal pipes must be used when this occurs consistently.
