replacing window in block wall with brick exterior
I'm replacing a window in a block wall that has a brick exterior. I will be removing the entire frame of the old window and was planning on using a replacement window without a nailing fin. But after looking at it further, the interior rough opening (leaving existing wood buck in place) is smaller than the exterior brick opening by about 1.5 inches on all sides. This would leave me enough room to use a window with a nailing fin. So my question; should I flash and use a stnd no nailing fin replacement window or go with the window wiht a nailing fin and then flash over the nailing fin?
