Heat and Acoustic Insulation

Spray polyurethane foam (SPF) is made by mixing and reacting chemicals to create a foam. The mixing and reacting materials react very quickly, expanding on contact to create foam that insulates, air seals and provides a moisture barrier. SPF insulation is known to resist heat transfer extremely well, and it offers a highly effective solution in reducing unwanted air infiltration through cracks, seams, and joints. There are different types of SPF. Here, we will discuss the types typically installed by professionals, which are either a high pressure foam and/or a low pressure foam.
