Can I insulate between brick veneer siding and the wall studs?
I have a home built in 1977 and my south wall is cold in the winter. Can I safely inject foam insulation in the air gap behind the brick veneer. The company that does this work told me it was okay to do this; however, no one I have asked that laid the bricks or sold the bricks thinks it is a good idea. They tell me that this area is needed to get rid of any moisture that might happen between the brick and the gypsum board backing. I have been told I need this space for moisture to evaporate. . I do have fiberglass insulation but this wall is still cold. When my brick was laid, weep holes were not put in because this was not done at that time. I have a hard brick so I don’t believe moisture is getting behind the brick as there is no sign of any moisture in the basement. My question is, do you think I can fill this space with foam?
