Let’s talk about spray foam insulation vs. fiberglass. Spray foam insulation is better than fiberglass — and not just for insulating your building. There are in fact a whole host of reasons why spray foam is better than fiberglass. Some of the reasons may surprise you!
Longer lasting, better insulating
First of all, although it may cost a little more upfront, spray foam — both open cell and closed cell — lasts longer and provides better insulation than fiberglass batts. In fact, over time, the money you save on your energy bills by using spray foam installation will more than pay for the slight increase in upfront costs. We call it lifetime insulation for a reason. Spray foam seals all voids, inhibits air leakage, and creates a protective air barrier, leading to better energy efficiency per square foot than installed fiberglass.
Second, spray foam adds a level of fire protection to your structure. All foam materials are considered flammable. However, the products we use at Spray-On Foam & Coatings have a class 1 hour fire rating.
Fiberglass insulation contains formaldehyde. Our products do not.
Mice and rats often chew into and nest in fiberglass insulation. They won’t be able to do that with spray foam insulation. Why? Our foam provides no food source or nesting materials for rodents.
Unlike fiberglass, spray foam insulation provides a measure of soundproofing to your structure.
Condensation be gone!
Spray foam insulation helps prevent condensation and makes it easier to control the climate within a building. This leads to our next benefit …
Improved air quality
Molds thrive in moist conditions. With inorganic spray foam insulation’s tendency to limit condensation and get the structure air sealed, there will be less mold and better air quality.
One of the more surprising benefits of spray foam over fiberglass insulation: stronger walls. When spray foam insulation is applied, it reinforces the walls and roof, making them more rigid and sturdy and less likely to fail during extreme weather and natural events.
FEMA reports that “all building materials below the BFE (Base Flood Elevations) must be flood damage-resistant, regardless of the expected or historic flood duration.” FEMA says that “only Class 4 and Class 5 materials are acceptable for areas below the BFE in buildings in SFHAs (special flood hazard areas). Spray foam insulation’s rating? Class 5 — the only insulation material rated that highly.
There are pros and cons to all types of insulating materials.
