Crawl Space Insulation in Stamford, CT

The old-fashioned way to insulate a crawl space was to install fiberglass batts between the overhead joists in the crawl space. This is no longer recommended for several reasons. In a crawl space, fiberglass insulation tends to absorb moisture, which causes it to lose R-value and fall out of place, rendering it totally ineffective while also creating a mess. To repair and insulate this crawlspace, we first removed the old insulation. To keep moisture from entering the space, we installed drainage matting beneath TerraBlock foam insulation on the floors, and the CleanSpace vapor barrier above it. On the walls, we used closed cell spray foam. It's perfect for a crawlspace environment! Closed cell foam cures dense and hard and is heavier than open cell foam, and it forms an effective barrier against both moisture and air. After we repaired and waterproofed the crawl space, the owners never had to worry about crawl space humidity and energy loss again!

Crawlspace Insulation in Stamford, CT

The problem with fiberglass insualtion in crawlspaces is that they are vulnerable to moisture. Instead of keeping the moisture out of the crawlspace, fiberglass batts absorb humidity, and lose insulation value when they do. When we arrived in this Stamford home, we found that the insulation had already grown heavy with absorbed water, and had fallen from the ceiling. After we removed the ineffective fiberglass insulation, we used closed cell spray foam in combination with our CleanSpace vapor barrier to block out moisture entirely. Closed cell foam is dense and waterproof, and provides an airtight seal along with a high R-value per inch. The owners of this home no longer have to worry about energy loss and high energy bills because of a leaky crawlspace!

CleanSpace Vent Cover in Stamford, CT

In old houses, it is common for crawlspaces to have open vented areas. It was believed that the vents would allow fresh air to circulate in the area and clean out the moisture and humididy from the room. However,  the air outside was often more wet and humid than the inside. Moist air that enters a vented crawl space will condense on cooler crawl space surfaces, ruining insulation and encouraging mold, mildew and wood decay to flourish. Crawl space sealing with our CleanSpace crawl space liner is the recommended treatment for a vented crawl space. This process involves the installation of different air and moisture barriers to totally separate and shield the crawl space from outside conditions. Plastic vent covers play an important role in a sealed crawl space by closing off the air movement that would otherwise occur through vent openings.
