If you have exposed walls or want foam insulation for your attic, then spray foam insulation is the best option for you. Spray foam is a two part component foam and comes as either a closed cell or open cell product. It mixes at the nozzle, but when it comes out, it sprays out at a much higher velocity and then expands rapidly as it adheres to whatever surface it is sprayed onto. Spray foam is good for applications where we are treating the joist ends of a basement, a crawl space ceiling, or exposed walls. Spray foam cannot be sprayed into closed wall cavities, it expands too fast and is too thick to be applied inside a closed cavity.
Spray foam insulation, also known as Spray Polyurethane Foam (SPF), is a fantastic material for insulating homes, and commercial and industrial buildings. Spray foam air seals the area that has been insulated, which can result in lower utility bills. Spray foam can also strengthen the walls, roof, and protect the structure from dust, mold, and rodents. It also has sound deadening properties.
