Learn about Fiberglass Blown-in Insulation

Fiberglass Blown-in Insulation

Loose insulation made of Fibreglass that can be blown or poured into wall cavities and attic spaces. Typically contains 20 to 30% recycled glass content.

R-value measures the insulating ability of materials. The thicker the insulation, the higher the R-value. Blown-in Fibreglass typically has an R-value of about 2.5 per inch, so a two-foot-thick layer gives you R60. Ask for a higher recycled content if available.

Provides good insulation value in places where you have a lot of space, like an attic, and is quite easy and quick to install. If your attic is accessible, this makes a good do-it-yourself project, just ensure you don't block the soffit vents in the attic with insulation, because they need to let air into the attic.

Some building supply stores will let you rent the fibreglass insulation blowing machine for <strong>FREE</strong> if you buy at least 10 bags of insulation.
