Many older homes and even newer homes still are not built with any insulation in the basement walls or rim/band joist areas. And, this can be a huge issue especially where moisture is concerned. Moisture in a basement promotes mold and mildew growth which can significantly impact your family’s health due to poor air quality in the home coming from the basement. Insulating your basement with spray foam insulation not only provides a moisture barrier it keeps your home environment healthier.
