    First time poster, apologies if I should have posted this in garden section.

    I've got a 44mm thickness log cabin. I want to insulate the floor. I'm thinking of laying Kingspan 25mm sheets on the floor, then an 18mm ply over it. Is that possible? Or could I lay carpet tiles/laminate direct onto the Kingspan?

    How do the Kingspan sheets join together, is there likely to be movement?

    You can't walk on insulation alone, it needs a board on top.

    Sounds silly, but how do I attach the ply to the floor of the garden office? Just screw right through insulation into the joists?

    I know the insulation 'floats' but surely the ply needs to be fixed somehow
