Spray Foam Insulation and Termites

 The building enclosure serves many functions, including the control of heat, air, and moisture. Creating an energy-efficient building enclosure meeting current energy codes requires proper design and installation of insulation and air barrier systems. Quality design and construction of the building envelope can be particularly challenging when it comes to controlling the damage caused by wood-destroying insects, such as termites.

Spray Polyurethane Foam (SPF) is a high-performance insulation that provides integral air sealing and moisture control benefits in a single product application. SPF helps seal cracks, gaps and penetrations in the building envelope in order to mitigate air leakage and deter infestation by a variety of insects, rodents, and other pests where it is applied. SPF is not known to attract nor does it provide a food source for termites; however, it can be accompanied by the use of new technologies when inspecting for termite infestations. It is important for SPF contractors and building design professionals to understand termites and how to apply SPF insulation to facilitate termite inspection and control.
