MASONRY QUESTION OF THE MONTH!
Question: Is foam insulation recommended in the cavity of a brick veneer concrete masonry wall?
Answer: Foam insulation eliminates the drainage space required to facilitate the removal of penetrating water, which will inevitably occur. While the foam is intended to insulate the wall, it does not prevent water issues. Foam insulation will often contain void which can trap water and create problems for the wall.
