What is spray foam ?
In terms of chemical explanation, polyurethane foam is the result of the chemical reaction of a part of Isocyanate and a part of polyol.
As a spray material (mainly) it has many features and its applications are multiple and we find them in many kinds of industries.
In our case, however, we are interested in its application in structural constructions.
In the construction industry can offer thermal insulation, sound insulation and waterproofing solutions (waterproofing foam of closed cells only) with excellent results and high performance.
Advantages & Applications
PU foam is applied by spray to roofs, tiled roofs, perimeter walls, pilotis, etc. or by injection into walls.
It still finds excellent application in the thermal insulation of livestock and poultry units, in refrigeration chambers and on large roofs of industrial buildings.
- Excellent adhesion to most materials like concrete, stone, wood, marble etc.
- Eliminates thermal bridges, since it has no seams and joints.
- It offers a significant improvement in energy costs for cooling or heating.
- It has the lowest coefficient of thermal conductivity from all other thermal insulating materials.
- Pervious from water vapor (vapor barrier must be applied where required)
- It does not add weight to the construction, so it is ideal in old buildings.
- It is applied to surfaces free from flimsy materials and moisture and sprayed in any direction (horizontally, vertically, inverted).
