Bathrooms are among the most frequently used rooms in the house. So, not surprisingly, controlling moisture from showering, bathing and washing is a major concern when it comes to installing insulation in bathrooms. This moisture vapor in the air is transferred along with heat, which is especially common in humid environments. When moisture vapor becomes trapped in walls, mold and mildew growth can result, damaging your home and presenting a potential health concern to you and your family.
You can avoid these problems by installing insulation that offers excellent moisture-control properties. To minimize the possibility of vapor collecting under the insulation, a vapor retarder is generally installed.
