Crawl Space Vent Insulation


crawl space vent insulation with foam board & spray foam for the best foundation seal

Crawl space foundation vents have been a hot topic in the building industry for the last five years. States like North Carolina are starting to change their building codes on new homes and are no longer required to have foundation vents. This change is because the codes are over 100 years old, and we now have a mechanical way to move and dry the air (dehumidifier).

During the summer, foundation vents let the warm air into the crawl space. This air then meets the cooler air and ductwork in the crawl space. The effect is like taking a cold Coke outside on a hot day. Condensation.

During the winter, the vents allow cold air to enter the crawl space causing hardwood floors to cool and adding to the heating cost of the home.

Crawl Space Brothers will seal your vents with insulating foam board and spray foam. This prevents moisture intrusion and the thermal exchange. It also allows us to install a dehumidifier to optimize the air space under your home. Give us a call to find out more!
