Hello, parts of my loft are boarded for storage without the leg raisers which allow you to go for thicker loft insulation.
I’d like to take the floorboards up, then put celotex insulation down, then screw boards back down.
What thickness celotex board do I need to achieve the recommended equivalent to 270mm wool insulation?
What I’d then like to do everywhere else is lift up the wool insulation, replace with celotex, then lay the insulation back on top (except where there’s floor boards already)
This is for insulation on the loft floor between the joists, not the roof.
Thanks!
