In other articles, we have already analyzed how polyurethane is formed and used as an insulation system or to manufacture some parts, among other applications. The mixture of the two components, polyol and isocyanate, which are liquids at room temperature, produces a...

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 gaps...

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.

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.

Poor sound insulation is a problem for buildings, not only in purely constructive terms, but it also has an impact on the well-being and health of its occupants. Therefore, the interior noise of buildings has become a problem that requires effective constructive...

Thermal conductivity is a physical property that appears in any material, including polyurethane, and it measures the heat conduction capacity through it, or in other words, the transport of heat energy through a body. This energy movement is produced by the difference...
