Sprayed polyurethane foam is a well-known product. Who has not seen polyurethane insulation at some time? In Europe, from the 80s to the present, tens of millions of square meters of polyurethane foam have been applied "in situ" in buildings. It is the so-called "sprayed insulation". But what have been the main reasons for the widespread use of sprayed polyurethane foam?
The performance of sprayed polyurethane foam applied "in situ"
Undoubtedly, among the first reasons is the high performance of the product. An applicator can apply 100 m2 in an hour’s of work, depending on his experience and the heterogeneities of the surface on which he is applying it. There is no need for setting out, no cuts, no joints, no fixings, no adhesives, no taping, etc.
The technology of sprayed polyurethane installation
The versatility provided by the projection technology allows the insulation of all types of surfaces in a simple way. The correction of thermal bridges is something easy to carry out with polyurethane foam applied "in situ".
The high performance of polyurethane insulation
The high performance and technology in the installation are complemented by the high performance of the product: maximum insulation with minimum thickness, impermeable to water, and a sealing effect that acts as a barrier against air infiltrations and humidity control.
These features have allowed, for many years, sprayed polyurethane foam to contribute to providing thermal comfort and protection to buildings.
Near-zero energy buildings
The need for energy efficiency in buildings goes hand in hand with comfort and protection of the external environment. Reducing energy losses in buildings has become the primary objective of regulators.
It is not just a matter of insulating more, but of using efficient solutions that offer the necessary performance to the walls that make up the building envelope. The correction of thermal bridges and the reduction of air infiltrations become priority objectives of regulation. It is of little use to place a high thickness of insulating material in the walls if the thermal bridges are not properly insulated or if air enters through the façade or through the joints with the openings.
The optimal performances of sprayed polyurethane foam, together with its adaptability to the requirements of nearly zero energy buildings, have been the reasons why it is on the rise in the countries with the highest energy efficiency requirements of buildings.
High energy efficiency buildings require a suitable thermal bridges treatment and a barrier against air infiltrations, which is achieved with the application of sprayed polyurethane foam technology, as these features are inherent to it.
