The Many Advantages of Polyurethane Spray Foam Insulation

When you go to buy insulation, there are several different types. It’s hard to immediately understand the positives and negatives associated with different types of insulation. Unlike other insulation, polyurethane spray foam insulation doesn’t sag, deteriorate, or mold like other types of fiberglass. It provides one of the best barriers to moisture, sound, and it increases your savings on your energy bill because it covers more space than other options (namely fiberglass and blown cellulose). Sometimes, these savings amount as much as thirty to fifty percent on your energy bills.

There are several notable benefits of polyurethane spray foam insulation (SPF):

The best non-permeable air seal

Polyurethane spray foam insulation fills to a space, filling gaps within framing systems. SPF acts as a tight, waterproof insulation, but it also protects your Gyproc from air contamination and vapor contamination. SPF is considered a “Vapor Retarder” which means that it completely prevents the transfer of gases. Other insulation is affected by wind wash, outside air, and moisture, which ruins its integrity and provides a lackluster end result.

SPF eliminates this, preventing mold, spores, pollen, dust, and other allergens from even entering your building envelope- keeping your family healthy and sneeze-free.

High R-Value

Polyurethane spray foam insulation has an R value rated at 6.2 units per inch (when cells are enclosed) and 4.2 per inch when cells are open. Closed cells have literally millions of tiny bubbles that reduce heat loss and prevent air current transfer between layers in your walls. In fact, SPF is one of the only types of insulation that doesn’t lose R-value over time (compared to blown or fiberglass types of insulation).

Excellent Sound Reduction Capacities

SPF is one of the only “soundproofing insulation” out there. It noticeably reduces outside noises (like traffic, airplanes, or barking dogs) when properly applied.


SPF qualifies for LEED, Energy Star, and a myriad of other energy saving programs. SPF doesn’t contain any CFC’s, HCFC’s, or other gases that harm the environment, nor does it have airborne fibers. You can expect your SPF to last for a very long time, and that puts money in your pocket.

You’ll love having polyurethane spray foam insulation. Not only will you not be spending extra on your home’s insulation, but you’ll also save a ton on your energy bills. With durability that lasts and lasts, you know you’re not making a bad insulation choice when you go with SPF in your home- no matter where you put it.

    I like spray foam than other traditional options.
