What Is Fiberglass Insulation?

Fiberglass insulation is a non-combustible material made from recycled glass and mineral-based ingredients you can pronounce. It is a tried-and-true insulation material that has been used for at least 75 years and is also the most thoroughly researched and tested insulation on the market. Commercial and residential fiberglass insulation has proven itself to be a prominent cost-effective way to get the comfort and energy efficiency you want.

    Types of Fiberglass

    This type of fiberglass insulation can be blown in or installed by rolling out batts of insulation. Blown-in residential fiberglass insulation, is perfect for use in attics or finished walls because of how the small particles fill evenly around utilities.
