A common 4-inch brick has an R-value of about 0.8, which is just slightly more than 1/2 inch plywood sheeting by itself. Depending on insulation choice, a wall built with 2x4 studs will have an R-value from 13 to 25.
Edit: I see someone else beat me to it. I'm a slow typer today...
- chrisseaton 5y agoWho's building houses with walls 4 inches thick? You have at least two layers of that, with a cavity in between.
- rootusrootus 5y agoTwo layers of 4 inch brick with a cavity would be roughly comparable to a normal wood studded wall with drywall on the inside, empty cavity, then a layer of sheathing followed by a layer of siding. In other words, awful. I would hope that in the brick cavity there is some proper insulation.
