Re: Refacing brick
First, you need to see what the fire codes in your area allow. Generally, there are minimum distances that the heat source must be from combustible materials (stove and flue proximity to the wall/combustibles ). On heat sheilds I've installed we've had to put metal furring strips on the wall then attach cement backer, then apply tile or faux brick. The furring strips act as a thermal break as well as allow airflow behind the screen to prevent the build up of heat on the wall.
Again, check what the codes require in your area because EVERY jurisdiction is different.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
