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...

Knowing the insulation needs of buildings is fundamental to improve their energy efficiency and so that they make a more intelligent use of energy. Therefore, designing their envelope with the optimum insulation thickness is the best strategy to get the most benefits...

Control of indoor air humidity is key to the healthiness of buildings. Even if at first glance we can not perceive the amount of water vapour that is present in the room, on average a person perspires between 3 and 5 litres of water vapour per day.
