Fredericktown spray foam insulation is ideal for crawl space insulation as it also does an excellent job of air sealing. Depending on your preference, you may cut off the crawl space from your home’s conditioned floors or condition it to achieve close to the upper floors’ temperatures.
Cutting off the crawl space involves applying spray foam between joists to the floor’s underside. This helps prevent air leakage from the crawl space and also prevents heat loss into the crawl space.
If you want to condition your crawl space, an insulation contractor will leave off the underfloor insulation and instead seal the crawl space against external temperatures and moisture.
Spraying foam insulation on the crawl space inside walls and crawl space ventilation to the outside helps shut off spaces through which air can leak in.
Using Fredericktown spray foam insulation on crawl space walls also provides a moisture barrier, preventing wicking by the inside walls.
Maintaining an airtight, insulated crawl space makes your house more energy efficient as it keeps your floors warmer during cold months, thus lowering your heating bills. The reverse is true in warm months – insulation keeps your floors cooler, lightening the load on your air conditioner.
