INSULATION OF CEILINGS WITH POLYURETHANE FOAM

About 20% of a building's heat loss comes from the attic and interfloor structures. A simple technological technique—insulating the floors with polyurethane foam—can significantly reduce this figure. Even a thin layer of polyurethane foam can reduce heating costs by more than 10-15%. Furthermore, insulating wooden floors of this type has excellent sound-absorbing properties.

INSULATION OF ATTIC FLOOR WITH PU FOAM

Insulation with polyurethane foam has become widely used in civil and industrial construction. The feasibility of thermal insulation using polyurethane foam has been proven not only by theoretical calculations but also by extensive practical experience, even in extreme climatic conditions.
The use of polyurethane foam for insulating interfloor ceilings significantly simplifies the installation of the insulation layer, and this technology also offers a number of other advantages.

• The low specific gravity of polyurethane foam helps avoid excessive loads on the building's load-bearing structural elements, which is especially important when renovating old buildings with wooden ceilings.
• Insulation with polyurethane foam can be used for interfloor ceilings made of various materials. Polyurethane foam adheres well to both reinforced concrete slabs and structures with load-bearing beams (metal, wood, reinforced concrete).
• For wooden houses, the material's high fire safety is especially important. Polyurethane foam is not only considered non-flammable (self-extinguishing), it also improves the fire resistance of the entire floor structure. This eliminates the need for additional fire retardant treatment of the wood.
• Insulating floors with polyurethane foam is a great way to absorb sound. Spraying polyurethane foam (in combination with other soundproofing measures) will eliminate noise from neighbors above.
• In many cases, using polyurethane foam for interfloor ceilings is necessary to provide additional waterproofing. Polyurethane foam has minimal moisture absorption, which is why this type of thermal insulation, when installed in kitchens, bathrooms, and other sanitary areas, can prevent water penetration during emergency situations in the water supply or sewerage systems on upper floors.
• Insulating wooden floors with two-component polyurethane foam has another significant advantage. This type of insulation is completely unattractive to rodents. If you are planning to build or renovate a country house with the goal of reducing heat loss during the heating season, be sure to consider using polyurethane foam. Otherwise, you risk losing your peace of mind due to mice's excessive love of polystyrene foam and certain types of rolled insulation materials.

In terms of cost-effectiveness, leading heating experts have recognized polyurethane foam as the most optimal material (among those currently in use) for thermal insulation.
 

Features of Insulating Floors in Country Houses

In log and frame houses, interfloor floors are installed on load-bearing beams, which makes the cross-section (relief) of this structural component quite complex. In some cases, thermal insulation with traditional slab or roll insulation is simply impossible. Even careful adjustment of individual insulation elements does not guarantee the elimination of "cold bridges," which usually form at the junction of the floor and the supporting rafter system.
Polyurethane foam can solve this problem and improve the effectiveness of insulation. Because polyurethane foam can cover all structural components of interfloor wooden floors with a uniform, seamless layer, the impact of low ambient temperatures on internal elements is eliminated.
