For those curious in understanding the science of spray foam insulation, the Spray Foam Coalition has developed a highly visual and simple infographic detailing how the two components of spray foam insulation come together to create the foam itself. This infographic helps anyone new to the industry or unaware of spray foam insulation understand the material, how it works and how it is made to provide both insulating value and an air barrier.
