Insulating a Bathroom
Proper insulation will help keep your bathrooms a comfortable temperature year-round.
Bathroom projects need special consideration because of the humidity and moisture that bathrooms generate. When moisture becomes trapped in walls, mold and mildew can grow, damaging your home and presenting a potential health danger.
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 (according to local codes).
