OK, daft question coming up. I think the optimum depth of insualtion would be deeper the beams in the loft. I want to floor the loft for additional storage. I think if I just get the flooring sheets from B&Q and lay them accross the beams compressing the insulation that will at least partially negate the effects of the insulation. So how do I easily lay the flooring without compressing the insulation? Thanks.
I had a question like this recently that I posted on mybuilder.com. They this an ‘Ask a Tradesman’ section which is quite helpful because tradespeople are the ones who answer your questions (instead of people like us that actually don’t have a clue :/).
