You can insulate a brick home but must cover up the brick.
Q: I have an older brick house and there is no room between the walls for insulation. Can I put the insulated panel on over the brick and put siding on over that? ? Dave, a Smart Choices reader
Mr. Tight Watt asked Bill McAnally, our energy-efficient home building expert , to advise Dave.
A: Yes, this is actually the newest recommended best practice for creating more energy efficient homes … working strictly on the outside, rather than messing up living space indoors. This practice started in cold-climate Canada, where, out of necessity, many energy-efficiency practices begin.
Here’s what you do:
- Put a minimum of 2 inches of polystyrene foam over the brick.
- Cover the house with house wrap.
- Add furring strips.
- Put the new siding on over top.
