Seal Tight Foam® Crawl Space Insulation

How many times have you seen round/oval vents penetrating from the crawl space into the house through rectangular holes?  This situation is cause for great concern.  We already know that fiberglass batts cannot control or prevent air/moisture movement and infiltration.  That being the case, even if your crawl space is “properly” insulated with batts, they will not prevent cold air, warm air, contaminated from entering the living space of your home.

Signs of Insulation ProblemsSigns of crawl space insulation problems

  • The floor above the crawl space is unpleasantly cold in wintertime.
  • During cold weather, you have to keep the heat going nearly all the time to be comfortable in rooms directly above the crawl space.
  • Mice or other pests have taken up residence in fiberglass insulation installed between joists in the crawl space.
  • Fiberglass batt insulation has fallen out of place from between floor joists in the crawl space.
  • The crawl space smells moldy or has visible signs of mold.
  • The crawl space is damp all the time.

Benefits of Rigid Foam Crawl Space Insulation

Crawl Space Insulation Installation
  • Stable and reliable. Unlike fiberglass insulation, rigid foam won’t compress, fall out of place or lose its R-value over time. It’s definitely a “once-and-done” improvement.
  • Effective air sealing. When joints between foam panels are taped, rigid foam stops air leaks that can waste energy. Fiberglass insulation can’t stop air movement.
  • Moisture-proof. Rigid foam won’t absorb moisture or be damaged by it.
  • Unfriendly to mold. Mold can’t take hold on rigid foam because it contains no organic food source and it doesn’t hold moisture.
  • Better ductwork performance. Ducts located in the crawl space benefit from rigid foam installed against crawl space walls.

Save now but pay later. Fiberglass batt insulation is inexpensive. But it doesn’t perform well or last long when installed between crawl space joists.
