Filling walls with a fluffy layer of fiberglass insulation is one of the easiest and least expensive ways to make your home more energy efficient.

Insulate exterior bathroom wall.

It will be cheaper on the wallet too. Place the insulation slabs or batts inside the wall cavity between the studs. Another path is foam pipe insulation which will keep pipes warmer during cold months. It s important to have no matter what weather conditions you live in though the way you install it may vary.

If the whole batt cannot fit inside the cavity cut off the excess material with a scalpel knife leaving a couple of centimeters over on each side to ensure a tight fit. Insulating a bathroom proper insulation will help keep your bathrooms a comfortable temperature year round. Because fiberglass tends to be more porous moist air is likelier to flow through it. Un faced batt type insulation with caulked joints for air sealing would allow for any moisture within the wall cavity to dry to the exterior.

All it takes is a utility knife a straightedge and a little patience to make sure the insulation completely fills the stud cavity side to side and top to bottom without being overly compressed. Buy unfaced friction fit batts and seal the walls with a 4 mil poly vapor retarder. Press the poly into the sealant. When moisture becomes trapped in walls mold and mildew can grow damaging your home and presenting a potential health danger.

A well insulated home keeps everyone comfortable and happy. Life s too short so enjoy it. Seal the gap between the bottom plate of the wall and the floor with acoustical sealant or caulk. In the best case scenario you can insulate the wall behind the shower during initial construction at the same time you insulate the rest of the exterior walls.

Use special airtight electrical boxes see photo tip 5 or seal the poly to the electrical box with acoustical sealant. Bathroom projects need special consideration because of the humidity and moisture that bathrooms generate.
