Rigid Foam Wall Insulation

When a crawl space is sealed, the insulation belongs on the walls instead of in the floor. Rigid foam board on the foundation walls keeps the space closer to the temperature of the house and protects against the cold soil and block.

We install rigid foam wall insulation in crawl spaces across Nashville and Middle Tennessee, cutting panels to fit, taping seams and tying the insulation in with the ground liner and rim joist sealing.

What you get

Done right, from the first walk-through

01

Foam board cut to fit

Panels are cut around piers, pipes and the rim joist.

02

Taped seams and sealed edges

Joints are sealed so air and moisture cannot move behind the foam.

03

Tied into the liner

The wall insulation and ground cover form a continuous layer.

04

Clean, durable finish

Panels are fastened securely and kept off the soil.

FAQ

Common questions about rigid foam walls

Is rigid foam treated for fire safety?

Foam board in a crawl space often needs a covering or thermal barrier to meet code. We tell you what applies to your product and your home.

Can I use it instead of floor insulation?

In a sealed crawl space, yes. In a vented one, floor insulation is usually the better choice.

Does it stop water?

No. It insulates and reduces air movement, so drainage and a ground liner are still needed where water is a concern.
