Polyurethane Systems for building and industry

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...

The high insulating capacity of polyurethane is not achieved in construction with any other commonly used insulating materials. This special characteristic is due to the structure of small cells formed by the foam and to the composition of the insulating gas...

In order to apply the sprayed polyurethane foam correctly, we should take a series of factors into account, ranging from atmospheric conditions to different types of of substrate and their temperature and water content.

Polyurethane, like all polymers, is an organic material and therefore combustible. However, there are polyurethane foams classified from C, s3-d0 to E, which must be applied according to the risk to which they will be exposed and in accordance with the requirements...

Sprayed polyurethane foam presents a magnificent adhesion on consistent, clean and dry substrates and, in general, to all the materials used in building. It should not be forgotten that polyurethane foam was discovered during research on a kind of glue.

Polyurethane systems are one of the most used insulating materials in construction, not only due to their good thermal behaviour, but also because of their acoustic properties. The insulation barrier formed by polyurethane is able to control the sound waves that are...
