hi there
what is the standard practice for filling the cavity gap between the twho skins where a door is going.
i have bi fold doors sitting on the outside skin and then have 80 mm insulation and 80 mm screed, should i knock the bricks that are sitting proud out and then fill the gap with concrete and then but the insulation up to the doors
