Insulation of polyurethane foam walls in Atyrau

Insulating walls with polyurethane foam

Insulating house walls, both inside and outside, is a necessity that's long been accepted. Despite developers' assurances about the excellent thermal performance of high-rise buildings, the first winter puts everything in its place. And standard Khrushchev-era buildings are out of the question. One of the most popular technologies today is polyurethane foam wall insulation, which allows for a quick and effective solution. This material's closest competitor, polystyrene foam, has many similar characteristics but is less easy to install. Installation of this insulation material requires the use of special adhesives and additional fasteners. [This text appears to be incomplete and likely a mistranslation.]

ADVANTAGES OF PU FOAM WALL INSULATION

Polyurethane foam can be used for both external and internal insulation. The material is certified for environmental safety, allowing it to be used even in the production of furniture or refrigeration equipment. When it comes to improving the thermal insulation of residential walls, external installation is preferred, as it will ensure the preservation of the interior space. However, due to the thin thickness of polyurethane foam required to ensure the required thermal performance, internal wall insulation is also a viable option if access to the external wall surface is not possible. So, what attracted developers to polyurethane foam?

• Minimal thermal conductivity (0.02 W/mK).
• Virtually zero moisture absorption and vapor permeability.
• Thanks to its excellent soundproofing properties, polyurethane foam wall insulation has proven itself in metropolitan areas. When combined with modern window systems, polyurethane foam minimizes the noise of busy highways.
• Coating walls with polyurethane foam significantly enhances the structure's protection from aggressive substances, which are often present in normal precipitation. Furthermore, polyurethane foam is resistant to mold and mildew, which helps extend the life of the home overall.
• When it comes to installing this insulation, its main advantage is its high adhesion to various materials. Polyurethane foam adheres perfectly to any surface, and, unlike standard mounting foam, it hardens quite quickly.

When choosing this wall insulation technology, remember that polyurethane foam requires protection from sunlight. Good results are achieved by insulating it in conjunction with a ventilated façade system or simply plastering the insulation layer.
 

EXTERIOR WALL INSULATION

In practice, two main technologies are used for external wall insulation:

• A ventilated façade system using polyurethane foam eliminates the need for additional waterproofing and vapor barriers on the building's load-bearing structures. Insulation is applied after the façade's load-bearing frame is installed, followed by the façade section. The resulting monolithic insulation layer has high thermal insulation properties.
• Insulating the walls of a house followed by plastering the surface is considered a simpler method of façade insulation. After cleaning the wall, a layer of insulation of the required thickness is sprayed onto it. It hardens quickly, creating a textured surface. To provide additional strength, the insulation is reinforced with fiberglass and a standard adhesive mixture; the process is similar to installing expanded polystyrene (foam) insulation. Once the reinforcing layer has reached the required strength, plaster is applied to the wall surface. The cost of this method of finishing facades with polyurethane foam is quite affordable, and the work is completed quickly; a medium-sized house or apartment can be insulated in just 1-2 days (with proper work management).

 

Insulating the interior walls of a house is best accomplished by pouring polyurethane foam behind the finishing (plasterboard covering). This technology significantly reduces the scope and, consequently, the cost of the work.
