New HUD publication about moisture-resistant homes
Insulation information is included in a new publication about moisture-resistant homes issued by the U.S. Department of Housing and Urban Development (HUD). Appropriately titled Moisture-Resistant Homes, the 125-page booklet says it is "a best practice guide" and includes a section specifically for homeowners. One suggestion is designing basement insulation and finishes to dry to the interior. "Low permeability and continuous vapor retarders, like polyethylene sheeting or vinyl wall paper, on the interior side of basement finishes should be avoided because they will tend to trap moisture vapor moving through the foundation wall and slow the drying process for new foundations. Therefore, unfaced fiberglass batt insulation and permeable paint finishes on gypsum wall board should be preferred on basement finished wall assemblies. Other proprietary basement finish systems, using products such as rigid fiberglass insulating boards, have also performed well in testing and use."
