For home insulation, the quality of spray foam insulation is superior to other types of insulation. Spray foam insulation exceeds other insulation types in regard to R-value, resistance to mold, air sealing, dependability and function. Spray foam insulation is very versatile in it’s use of different applications, including attics, crawl spaces, and walls.

You’ve probably heard of 1- and 2-part foam. The 1-part foam can be found in most home improvement stores, is packaged in a spray can and is mostly used to seal cracks and small gaps. For home insulation purposes, we use a 2-part foam application contractors call a “kit”. This kit is used for larger jobs and is a system made up of separate ingredients that are mixed onsite to start a chemical reaction that expands. The catalyst compounds are pumped into an application nozzle and applied to the specific site of insulation.

Spray polyurethane foam, is the main type of 2-part, closed-cell spray foam used by insulation contractors. Large-scale insulation jobs require special equipment as well as safety gear to protect the installer from chemical fumes during installation. When the foam cures and hardens just several minutes after application, it’s completely safe for as long as it stays in place.

Closed-cell spray foam insulation is the most expensive residential insulation. When it is installed well, it performs better than any other insulation. It is an excellent air barrier, is impervious to moisture, and is an effective vapor blockade. The R-Value in closed cell spray foam is R-6.5 per inch and is most often used in walls, ceilings, roofs and under slabs.

Because of spray foam insulations density strength it adds structural strength to a wall, ceiling, or roof. To seal air leaks in rim joists or the attic side of partition top plates, closed-cell spray foam is an extremely useful material. It is also more resistant to water than the open cell foam deters mold and mildew.
