Polyurethane systems are the result of the reaction between two chemical components, isocyanate and polyol. The best known applications of polyurethane are by projection (projected polyurethane or spray foam) and by injection, the one that concerns us in this...

Noises inside buildings have become a problem that requires effective solutions such as acoustic insulation. The interior comfort of the occupants of a building must be guaranteed in accordance with current regulations and through optimal building practices.

The filling of the air gap of a wall is one of the techniques that can be carried out with polyurethane, as it adheres as required to the walls of the gap, something that cannot be achieved with other insufflated insulating materials such as cellulose, mineral wool...

In previous articles, we have discussed the role of polyurethane systems not only as insulators, but also as stabilizers. In the article on the renovation of metal roofs, we stressed the importance of the structural role that polyurethane acquires in the renovation...

The application of injected polyurethane is mainly used in the filling of air gaps in façades or partition walls, mainly in cases of renovation works, in order to obtain optimal thermoacoustic insulation. In these cases, great care must be taken when filling the...

Injected polyurethane is an ideal material for the thermoacoustic renovation of façades and dividing walls between dwellings, since large works or machinery are not required for its installation, nor demolition works. When injecting polyurethane into the cavity...
