5 Ways Spray Foam Outperforms Fiberglass Insulation

Did you know that 90% of U.S. homes are under-insulated? Your fiberglass insulation is part of the problem. Spray foam is replacing fiberglass as the new standard because it’s more energy efficient and has a longer lifespan which makes it cost-effective, among many other things. The professionals at Foam Bear Orlando are here to show you 5 ways spray foam outperforms fiberglass insulation to encourage you to give your property the facelift it deserves!

1. Spray Foam Has A Higher R-Value Than Fiberglass

The main reason for using fiberglass or spray foam is to insulate, so we’ll start by comparing each material’s ability to maintain temperatures. Fiberglass has been the most commonly-used insulation for decades which is why it may come as a surprise that it’s such a poor insulator. Both types of spray foam (open-cell and closed-cell) have much higher R-values compared to fiberglass which immediately makes it a better choice.

2. Spray Foam Does More Than Just Insulate

Aside from being a poor insulator, insulating is all that fiberglass can do. It doesn’t keep out pests, prevent drafts, or add to the building’s structural integrity. You probably weren’t expecting insulation to do more than regulate indoor temperatures anyway, which is why the additional qualities of spray foam come as a pleasant surprise:

3. Fiberglass Can’t Match The Durability Of Spray Foam

A lesser-known fact about spray foam is that it can actually add more strength and durability to the existing structure that it’s being applied to. To be more precise, top-quality spray foam (when installed correctly) can add as much as 250% racking strength to the walls and roof of a building. On the other hand, fiberglass does nothing to improve the strength and durability of the surrounding walls.

4. Spray Foam Can Completely Close Up Gaps

How do you think that spray foam keeps out pests and prevents drafts? The answer lies in its ability to completely seal off any gaps or cracks in the walls or ceiling, no matter how small. This is the most effective way of preventing common problems with bad insulation such as mold growth, polluted air, increasingly high energy charges, and more. Since fiberglass is just a sheet that’s fitted into the walls, it’s incapable of making a tight seal which is why you will often experience these common problems.

5. Spray Foam Has A Much Higher Lifespan Than Fiberglass

The icing on the cake with spray foam insulation is the fact that it can last around 80-100 years without maintenance. This means that once you install spray foam, you’re basically set for life! When you compare that to the lifespan of fiberglass insulation (around 10-25 years), it’s easy to see how spray foam can save you money in the long run.
