Don't forget the Basement

CertainTeed offers several fiber glass insulation products designed specifically for basements and areas with masonry wall construction where cavity depth is limited. Basement wall insulation is designed for use in both residential and commercial projects where code or builder preference specifies an insulated basement area. This insulation is available with two perforated facings, white PSK and standard FSK; both insulation/facing combinations comply with ASTM C665 Type II, Class A.

Masonry wall insulation is unfaced and designed for use behind paneling and in masonry-type construction where cavity depth is limited. It is not as thick as basement wall insulation and is sized to fit tightly between furring strips, so no stapling is required.

These insulation products may qualify for energy tax credits. For more information, visit the CertainTeed Energy Tax Credit page, or certainteed.com/itools for your area’s specific rebates and incentives.

CertainTeed cares about the environment and Building Responsibly™, and for more than 100 years has maintained a commitment to provide sustainable, innovative solutions that improve energy efficiency and comfort. From production to product, CertainTeed's focus has been on minimizing its impact on the environment by reducing energy consumption, conserving renewable resources and lowering greenhouse gas emissions.

Check your local building code requirements.
Basement Wall Insulation is installed horizontally either half-wall or full wall, starting at the sill plate.

Half-wall application:
  • Nail a 2" x 2" furring strip to the edge of the sill plate at the top of all walls to be insulated.
  • Fasten a second row of 2" x 2" furring with power-actuated fasteners 48" or 72" below the sill plate furring, depending on the width of the insulation used. The 48" or 72" measurement must be the clear opening between both rows of furring.
  • Roll out the insulation and staple to the upper and lower furring strips with the facing exposed.

Full wall application:
  • Fasten a third row of 2" x 2" furring, 1/2" to 1" from the floor.
  • Staple a second roll of insulation to the center and lower furring strips. The second roll may have to be cut to fit. If so, cut the insulation and facing to a width equal to the clear opening dimension between the furring strips plus 11/2", then cut back the insulation 11/2" in order to form a stapling flange at the bottom.
  • Please contact CertainTeed prior to using an alternate method of installation.
