The answer to this question is usually 316 Insulation along the lines of “it’s a plastic foam that comes out as a liquid and expands when sprayed.” This creates a custom, airtight seal in the spaces where it is applied. It is often used to insulate and air-seal ducts, attics and crawl spaces. It can also be used to insulate and air-seal band and rim joist areas.
Spray polyurethane foam (SPF) insulation is a type of building insulation that is made up of two liquid chemical components that undergo a quick chemical reaction to form plastic foam insulation. This material can be sprayed onto roof tiles, concrete slabs and into wall cavities or into stud walls to provide insulation in new construction projects.
Spray Foam Insulation 101: A Guide by 316 Insulation
Open-cell spray polyurethane foam is made up of small cells that trap an insulating gas (typically a blowing agent) within them. This gas has a lower thermal conductivity than still air and increases the R-value per inch of this type of foam. Closed-cell spray polyurethane foam is rigid, hard foam that is denser than open-cell spray polyurethane foam. It offers a higher R-value per inch than open-cell foam and can also improve the structural integrity of certain framed buildings.
Choosing the right spray foam insulation is a big decision. While DIY kits are available for those confident in their skills, it’s best to let a trained professional do the job. This is because spray foam insulation requires a high-pressure application and can release chemical compounds into the environment that must be properly mixed and cured. This process can produce odors that have been described as smelling like fish, cat urine or fresh latex paint.
