We are installing Knauf GifaFloor FHB18 as a flooring substrate. We also have between joists spreader plate UFH.
After the plumber installed the spreader plates and pipes, we found the joists the builder did were approximate 400 centres and not exact. The result, in a 4x3 bedroom, not all joins would be on joists.
Do I need to make them take up all the UFH and put down some support timbers, at where those supported joins would lay? Or am I worrying too much about this?
