Spray Foam and Building Codes

If you’re thinking about installing spray foam, you probably have some questions about its compatibility with the building codes. Spray Foam and Building Codes

Every spray foam insulation code is different but spray foam meets stringent fire safety standards and complies with R-value requirements, making it a safe choice for homes. It also improves energy efficiency by creating a tight seal in walls and attics. In addition, spray foam insulation helps to prevent moisture issues like mold and mildew by keeping the air dry.

Most spray polyurethane systems have two components: the “A” side and the “B” side. The “A” side is typically comprised of methylene diphenyl diisocyanate (MDI) or polymeric MDI, and the “B” side includes a mixture of polyols, catalysts, blowing agent, flame retardant and surfactant. The ingredients in the “B” side help to trigger the chemical reaction that creates the foam.

Closed cell spray foam uses a blowing agent that contains hydrofluorocarbons. These chemicals have a very high global warming potential, or GWP, which makes them more damaging to the environment than carbon dioxide. Open cell spray foam uses a different blowing agent that doesn’t contain hydrofluorocarbons and has a lower GWP.

Both types of spray foam have the same fire and R-value compliance, but the installation process can be slightly different. For example, crews need to prepare the area where the foam is going to be sprayed before it’s applied. This usually means putting tarps down on the floor or moving any items in the area that could be damaged by the spray foam.
