Insulating crawl space with foam insulation

The best crawl space insulation. For extra comfort & energy savings, we recommend installing SilverGlo® rigid foam insulation against crawl space walls and TerraBlock™ flexible foam insulation on the crawl space floor, beneath the moisture barrier.

Crawl space insulation   

It's smart to include insulation in the crawl space encapsulation process. While encapsulation seals the crawl space to prevent outside air and moisture from entering, it doesn't stop major heat loss through the walls and floor of your crawl space. That's a job for crawl space insulation.

We don't recommend insulating the crawl space with fiberglass batts. Batts will absorb moisture, compress, fall onto the crawl space floor and encourage mold growth.

The best way to insulate your crawl space is to install SilverGlo® rigid foam insulation against crawl space walls and TerraBlock™ foam insulation over the floor. Both types of insulation offer high R-value, stability and durability. SilverGlo™ and TerraBlock™ won't absorb moisture, support mold or deteriorate over time. Insist on these two high-performance products if you want to do it once and do it right.


Basement insulation

Many homes have basement insulation in the form of fiberglass batts that are installed between basement ceiling joists. Unfortunately, this treatment only insulates the floor above; it does nothing to make your basement more comfortable and energy efficient.

Insulating and finishing basement walls

Insulating & finishing made simple. Basement to Beautiful panels provide basement wall insulation and waterproof steel framing in a single step.

Insulation for your basement walls

For basement insulation that makes your basement more comfortable and your entire home more energy efficient, you can't beat the performance and value of our Basement to Beautiful® wall panels.

These innovative panels combine high-performance SilverGlo® rigid foam insulation and steel nailing flanges that make it easy to install finished wallboard. Unlike fiberglass insulation and wood-framed basement walls, SilverGlo™ wall panels can't be damaged by moisture; nor will they compress, lose R-value or provide nesting space for mice and other pests.

Wiring channels have been incorporated into each panel to make it easy to install wall outlets, switches and lights.
