Closed Cell Spray Foam Insulation exceeds other insulation types in regard to R-value, resistance to mold, air sealing, dependability and function. Closed Cell Insulation is superior to all other types of insulation. Closed Cell Spray Foam is very versatile in it’s use of different applications including attics, roof decks, rim joists, ceilings, crawl spaces, and walls.
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 insulation purposes, we use 2-part closed cell spray foam insulation.
Closed Cell Insulation 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 compounds are pumped into an application nozzle and applied to the specific site of insulation. Closed cell insulation is made from polyurethane and isocyanate. When applied open cell reduces air leakage better than any other type of insulation. It fills the nooks and crannies of unusually shaped building cavities easily.
Large-scale Closed Cell 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-7 per inch and is most often used in walls, ceilings, roofs and under slabs.
Because of closed cell spray foam insulations density 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 also deterring mold and mildew.
