Hi, My first post so here goes (I've done a search)
I'm replacing the insulation in the loft and I'm going to board part of it out. I'm installing 100mm between the joists and, in a 5m x 3m area I'm going to put down 2 layers of space board both layers of which need to be glued with no more nails; on top there will be a sheet of standards T&G chipboard loft flooring which is glued at the T&Gs.
In the affected area there are 3 lengths of timber (standard T&G), on spanning the whole loft and two spanning several joists near the chimney breast - all acting as joist binders. If i lay the insulation on top of these then the floor wont be stable or level
Here's the question: Will the combined two layers of insulation and chipboard all provide sufficient rigidity to the joists such that I can remove the binders to provide a flat surface?
The whole loft is 7m x 5m so not too big and there'll be a couple of metres around the boarded area
