Fiberglass Batt and Roll Insulation

Interior of house without wallboard. Batt insulation is visible between wall studs.
Two sizes of batt insulation. One is several inches thick and a few inches wide. The other has a smaller width and is about an inch thick.

Fiberglass insulation delivers exceptional energy efficiency and thermal performance that result in more comfortable living spaces and lower energy costs for homeowners.

Heat constantly moves to colder areas, which is why homes need thermal resistance (measured by R-Value) between the indoors and outdoors. The higher the R-Value, the greater the insulating power.

CertainTeed fiberglass insulation is compression packaged for ease of handling and comes in a wide range of R-Values, sizes and facings. It’s critical to determine the recommended R-Value according to your region. However, code is a recommended minimum.
