- Stops air and moisture infiltration in the home
- Reduces energy consumption in the home by up to 30%
- Brings the cold floors within 1-2 degrees of the thermostat
- Eliminates condensation on the underside of the floor, reducing the chance of mold and mildew
- Closed and open crawlspace assemblies, both are great!
Crawlspaces are yet another culprit of energy loss through air infiltration, and therefore, moisture. Crawlspaces allow for air infiltration through the subfloor and then up through the ceilings in what’s known as the “Stack Effect”. Warm air rises through a home pulling cool damp air from the crawlspace. With spray foam you will air seal your subfloor, eliminating air infiltration and inherent moisture problems in the home. (mold & mildew)
The next benefit of spray foam is the elimination of thermal transfer through the floor. If you have a tile or wood floor, you know that it can be freezing in the cooler months. By applying foam to the underside of the floor, you can now expect the floor temperature to be within a few degrees of the house temperature year round.
Crawlspaces can be sealed in between the floor joists, separating the livable space from the crawlspace, also known as an open crawlspace assembly. Now homeowners can leave their vents open most of the year without worrying about cold floors!
In some situations, closed crawl space assemblies are the better option, sealing the foundation as well as the dirt/gravel with a vapor barrier. In this assembly, the crawlspace becomes part of the conditioned envelope.
