SPF (sprayed polyurethane foam) is used to seal the entire "building envelope" of your home to prevent air an d moisture infiltration.
SPF systems are frequently used to insulate and protect a wide variety of residential, commercial and industrial buildings. SPF seals cracks and crevices, it also insulates hard to reach places.
Two-pound spray foam, also known as closed cell spray foam, has an R-value of 6 per inch, making it perfect for insulating walls, ceilings, and attics.
Closed cell spray foam acts as an air and vapour barrier, and is applied by trained and certified applicators. It is also an alternative to traditional building insulation such as fiberglass batt insulation. Other benefits include reductions in noise, dust, pollen, pest infiltration and significant improvements to structural racking strength of wall assemblies.
Half pound spray foam, also known as open cell spray foam, is the most cost-effective but because of it's lower R-value, it is not approved for vapour and fume control. Aside from this, open cell foam has the same characteristics as two pound foam.
Both open and closed cell foam have air barrier qualities that can help reduce noise from outside the building envelope (i.e airplanes and car traffic). The open cell foam's density offers additional sound absorbing qualities, however neither foam is exceptionally effective at reducing vibration impact noises.
SPF application requires complex equipment and a skilled installer. In Canada ,residential and commercial applications must be done with certified foam and trained installers.
A slight odour will be present during installation of SPF. This will rapidly dissipate after the spraying operation stops and then remain odourless.
