Quality & economy crawl space insulation services

Technical Features

  • Brings crawl space up to current national code
  • A white foil finish on the front & foil vapor barrier on the back
  • Polyisocyanurate foam insulation panels that won't soak up moisture
  • Provides substantial energy savings

Foamax is a polyisocyanurate foam insulation that has a white foil finish on the front and foil vapor barrier on the back. With this innovative, multi-purpose design, our crawl space insulation provides multiple benefits, including a high insulating value, making your below-grade space brighter, improving overall crawl space comfort, and more.

If you're interested in keeping your crawl space dry to help prevent mold, rot, and musty odors, this is the product for you! Foamax also creates a vapor barrier on your crawl space walls that keeps moisture from making its way into your crawl space, where that moisture would help mold, rot, and mildew growth.

Foamax is part of a crawl space repair system that includes our TerraBlock™ Floor Insulation and our CleanSpace® Vapor Barrier. We also have several crawl space waterproofing products such as our SmartSump™ Sump Pump system to control flooding, our SmartPipe™ Drainage System, the only drainage system made specifically for crawl spaces, and our durable CleanSpace® Drainage Matting.

What NOT to do

fiberglass insulation dripping off the ceiling of a crawl space in Germantown.

As fiberglass insulation becomes soaked with moisture in a crawl space, it will grow mold and "drip" off the ceiling.

Far too often, we see crawl spaces vented, with fiberglass insulation on the ceiling.

Crawl space vents bring humid air into a home during the summertime, where it's cooled in the crawl space.

As this air cools, the relative humidity of the air rises, and the excess moisture is left on surfaces in the crawl space in the form of condensation.

Some of this moisture ends up on the fiberglass insulation in your crawl space. Wet or damp fiberglass insulation does not insulate as well as dry insulation, and the added weight will pull it from the ceiling, leaving it in messy, useless piles on the floor.

Wet insulation can actually become a food source for mold and rot--which will also grow on any other organic material in your crawl space--including your wood framing.

Additionally, while you're insulating your floor, you probably have utilities in your crawl space, such as your water heater, furnace, heating ducts, and hot water pipes. If you allow the cold winter air into your home through crawl space vents, these heat-generating utilities will be forced to work that much harder.

In short--crawl space vents and fiberglass insulation simply do not work!
