How to Install Insulation in Walls
Why install insulation in walls? An insulated home is one of the best ways to ensure energy efficiency and indoor comfort. The below video walks through exactly how to insulate walls in a home, including what resources and products to use.
Properly insulated exterior walls serve as a barrier between a home and the outdoors, helping to prevent condensation and the transfer of heat, moisture and air between spaces. When insulating exterior walls, Kraft-faced insulation is particularly effective at keeping moisture out of the walls where it could condense and cause mold and other problems.
Insulating interior walls helps reduce sound transfer, increasing privacy between rooms, and preventing draftiness, which can contribute to reduced heating and cooling bills. Unfaced insulation works well for interior walls and floors.
