Insulate Uninsulated Brick Walls
Insulate uninsulated brick walls. Uninsulated brick walls are very common, especially in buildings constructed prior to 1960. These walls can be insulated using three methods-furring the interior surface, insulating the cavity or insulating the exterior. Furring the interior surfaces is relatively simple, inexpensive and provides a finished wall surface. Generally, the interior is framed with studs or runners, insulation is placed between the runners, and the surface of the wall is finished.
