Things You May Never Knew About Polyurethane Insulation

Many people-homeowners and even constructors-don’t know that there are other insulating products besides fiberglass . One of which is polyurethane foam. Today I am surprised by how little the construction industry and homeowners know about this great product.

Polyurethane foam insulation is a major innovation in home insulation technology. For more than 40 years, spray foam insulation has been providing year-round comfort in homes across America. Federal and state energy-saving education groups refer to spray-in-place foam as one of the most efficient means of insulating your home.
Energy savings, comfort, air and moisture infiltration-polyurethane insulation does it all.

This remarkable system provides extremely high R-value (R13 at 2-inch thickness). Closed-cell insulation also creates a permanent air barrier and vapor diffusion retarder (VDR); protecting your home’s interior from dust, pollen and moisture infiltration, while strengthening walls. Its closed-cell structure provides superb noise reduction to make even a busy life peacefully quiet. And it’s environmentally friendly, too. But best of all it helps save money on heating and cooling costs year after year.
Professionally installed insulation is applied by specially trained contractors to the inside surface of exterior walls, to the underside of the roof, and beneath floors in basements and crawl spaces during new home construction or home remodeling. The two-part spray mixture expends rapidly to fill all gaps and voids, completely and permanently adhering to wood, masonry, metal, studs and joists. It is best applied after rough plumbing, electrical wiring, and heating and air conditioning ducts are in place and before interior wallboard is installed.

Most spray foam insulation is formulated to inhibit mold, mildew and bacterial growth.
Spray-in-place insulation never settles shrinks, compresses or sags.
Spray foam insulation has higher density (nominal 2 lbs/ft3 of foam) for higher R-value and more efficient vapor and air retardation.
High-density, closed-cell insulation strengthens walls with more than twice the racking strength of so called “soft” open-cell foam insulation products.
Homes insulated with polyurethane foam use less energy for heating and cooling and can often be served by smaller heating and air conditioning units.
