A great way to improve the comfort and energy performance of a home is to apply Spray Foam to the rim joists at the top of the basement foundation walls. This space can often allow outside air and temperatures to impact the home. Cold or hot air from outside can cause temperature fluctuations and can carry in dust and allergens that can impact the air quality in the home. 50% of the air inside of a home comes from the lowest points of open air access in the home so creating a low point that is not in or near a basement can keep moisture out as well. Our production crew applied Spray Foam to this entire basement at all of the rim joists and created and air seal along with better insulation.
