Choosing insulation may not be the most exciting part of designing a custom home, but the right material can make a big difference in your comfort and energy efficiency. Fiberglass insulation is one of the most popular options. Here’s a quick guide if you're considering it. 

What to Know About Fiberglass Insulation

What's it made of?

Fiberglass insulation is made from a mixture of sand, glass, and fibers. It's usually arranged into batting or rolls of material, but it can also be cut into smaller pieces and blown into a tight space. The fibers surrounding the glass create tiny pockets that trap air, which is how the material prevents heat loss.

Where is it used?

Fiberglass insulation can be used in any area that requires temperature or noise insulation. The batts and rolls are commonly applied to attics and walls, and blown-in fiberglass is used in tight spaces, like the corners of attics. Fiberglass isn't common in basements and crawlspaces since it doesn’t resist moisture.

What are its benefits?

This material is an economical option because it's fairly quick and easy for professionals to install. It's also extremely versatile since it can work in a variety of spaces. By using fiberglass insulation, you'll keep your home comfortable and energy-efficient without a steep upfront cost.

Are there any alternatives?

Fiberglass isn’t the only type of insulation available to homeowners. Spray foam insulation is a type of resin that's sprayed and then hardens into place, creating an airtight barrier. There’s also vapor barrier insulation, which includes a thin film to prevent moisture from entering a space.
