I wish to board my loft with 18mm chipboard T&G. It will only be approx. 1 metre around the perimeter, mainly for additional storage space. Looking at previous postings this looks fine to do but what if I decided to board the total floor area? Would the weight of all the flooring AND the storage be too much for the joists?
If anyone can give me an answer on this one I would be truly grateful. The joists are approx. [b]80mm deep x 55mm wide[/b] and are spaced at 360mm intervals from centre to centre of joists.
I have looked at the TRADA website to find this information but nothing seems to relate to these sized joists.
