Hi all,
We have 2 floor length windows in our new home and we have noticed there is a gap ranging from 1 inch to 2 inches between the edge of the slab and the frame. The fix suggested by the builder is to use expanda foam to fill most of the gap then use ardex on top. Is this normal? I wonder about the "life" of the expanda foam and whether is will break down over time compromising the integrity of the flooring in that area.
Any thoughts?
