The customer recently moved to the area and purchased this home, which was in desperate need of better insulation. The customer's goals were making the home more comfortable and energy efficient at the same time.
In the crawlspace area, we covered the earth with a 30 mil liner and sealed the liner around the perimeter walls with closed cell spray foam insulation. The liner helps prevent mold and mildew growth as well. This created a continuous seal around the foundation, as all vents are sealed up. The rim joist area was insulated with spray foam insulation and a dehumidifier was installed and drained to the outside of the foundation. We also installed a new crawlspace access door. In the attic, the roof deck was insulated with a nominal 6 inches of open cell spray foam insulation. This brings the attic into the thermal envelope of the home, ensuring that the attic space stays a more consistent temperature and a healthier place for storage items. Both of these projects together will make the home much more comfortable...less drafts, less humidity, cleaner air, and a more comfortable temperature without overworking the HVAC unit.
