Fiberglass insulation’s main component is fine glass fibers, derived from natural ingredients such as sand and recycled glass products like windows and beverage bottles. Fiberglass is the most widely used home insulator, and is also used to reduce noise transfer room to room.  

Fiberglass insulation comes in a variety of R-values, and is manufactured in batts and rolls.

Installing fiberglass in batt form is the application most homeowners think of when they think of insulation. The product is delivered in rolls (or wide sections that have been cut from a roll). The insulation may have kraft paper covering the wide sides of the product. This allows the insulation to be easily fit into a cavity, whether it is between wall studs, floor joints, or any other space.

We install batt insulation from CertainTeed and Johns Manville.
