Insulate Brick Walls

Uninsulated brick walls are very common, particularly in buildings constructed prior to 1960. You can realize significant energy savings by adding insulation using one of three methods: furring the interior surface, insulating the cavity, or insulating the exterior. Furring the interior surface is the simplest and least expensive approach, and provides a finished wall surface. Generally, this method entails framing the interior with studs or runners, placing insulation between the runners, and finishing the surface of the wall.
