Spray Polyurethane Foam (SPF) is a type of insulation material formed by the reaction of isocyanate and polyol resin components. When sprayed, it expands rapidly to fill gaps and cavities, creating a seamless insulation layer.
SPF has several notable characteristics. It offers excellent thermal insulation performance, with a low thermal conductivity that helps reduce heat transfer, thus saving energy in buildings. Its air – sealing property is remarkable, effectively preventing air leakage, which in turn improves indoor comfort and energy efficiency. Additionally, SPF has good adhesion, firmly sticking to various substrates such as wood, concrete, and metal. It also provides some level of sound – dampening, reducing noise transmission. Moreover, it is highly versatile, suitable for a wide range of applications, including residential, commercial, and industrial buildings, as well as in roofing, wall insulation, and crawl – space insulation
