Nearly half of the heat loss in buildings is caused by the roof, that is why proper thermal insulation is especially important here. Sprayed foam can be used to effectively solve the heat and water insulation of the roofs of detached houses. Protection against powder snow, and drafts caused by the wind. Say goodbye to high heating and cooling costs, temperature fluctuations - insulate with foam! The foam provides perfect thermal insulation in the attic against summer heat and winter cold. The attic will not be a danger zone, its temperature will be almost equal to the ground floor parts. Due to the vapor diffusing properties of the foam, the housing remains breathable, thus preventing mold and mildew. Remember: the foam gives a waterproof layer, so you are double protected against soaking under two roofs!



Over the years, it collapses and moves under the influence of gravity.

Does not provide waterproofing. It molds from the steam.

They break down after 10-20 years

It is permeated by air, the wind blows through it. When the cold air reaches the wall of the living space, the thermal insulation material is worth very little.



Rigid, not shape-following. Curved walls, columns and special shapes are impossible to insulate professionally.

It cannot be fitted exactly everywhere, it can cause several errors: thermal bridges, mold.

The insulation is not airtight, the surface is not airtight, the wall is strong.



Half of the thickness is sufficient - the thickness of the rafters does not impose narrow limits on the insulation.

Waterproof, vapor barrier, non-moldy.

Rigid, compact structure, insulation is stable, does not tear. Rodents do not move into it.

Its service life is several times that of traditional insulation materials.


It is possible to apply the foam from the inside: plasterboard, paneling, wood, vapor barrier film, tiles, etc. Big advantage is that the material can be applied to the surface of the choice without gaps, the heat cannot evaporate in the air gaps between the surfaces. The rigid insulation layer also statically strengthens the roof structure. The material adheres well to all surfaces, the insulation fills all the gaps, thus eliminating the energy-destroying air movement through the gaps by 100%. The thickness of the rafters does not set an upper limit on the insulation.


If the attic is inhabited, we insulate it from the outside. To do this, we need to remove the tile or other roofing material. If necessary, the existing thermal insulation and the steam closing foil are also removed. The foam is blown onto the outer wall of the living space limiting layer (plasterboard, paneling, wood). The closed-cell foam is watertight in its own material and therefore does not require foiling on either the inside or the outside. tiles can be returned to the roof.


The PURTECH team is just insulating. We cannot undertake the carpentry and plasterboarding that often occur in connection with attic insulation. If requested by the customer, we will bring a reliable subcontractor to move the roof cladding, build an osb reception area, and make a plasterboard covering.
