Polyurethane foam is considered a “progressive material”, since its creation is an important achievement for the construction sphere that is engaged in insulation work. The material has the following properties that make it indispensable:
does not absorb moisture;
low thermal conductivity;
elasticity;
lack of seams when used;
Safe;
excellent adhesion to various materials.
Canada and the USA were the first countries in which they began to use polyurethane foam. A great feature of the material is that it can be used in hard -to -reach places. If you want to build a house from a profiled timber, you can use foam to eliminate joints and cracks. With the help of sprayed foam, you can repair the old roof covered with roofing material. The material has a closed -porous structure. This means that it has good waterproofing properties. Therefore, PPU is used for waterproofing basements and attics. It is very important that PPU has a monolithic and homogeneous structure. Thanks to this, seams and cracks do not appear on the surface of the material. PPU prevents condensate, and this is very important for the construction structure. PPU is an elastic material. Therefore, it does not deform, does not crack and does not relax. The material also has vibration resistance. PPU studies have proved that the material is environmentally friendly and harmless. This makes it possible to use it in residential buildings. Another plus of the material is that it has a small weight, so it is easy to work with the material.
