Shed Floor Insulation

cletus

Insulating a shed, but can't access beneath the floor to insulate, so it will have to be done inside.

I see in another recent thread that Kingspan and 12mm OSB is recommended, but I've a few questions.

What's the best way to fix the insulation boards and OSB

Would EPS work as well as the Kingspan (this is what I'm doing the walls and roof with

Could I use, say, 6mm ply instead of 12mm (well 11mm actually seems to be standard) OSB to save some of the height loss, considering the ply should be sitting flat and flush on the boards

Thanks in advance

I have kingspan directly on my concrete floor, with the ply cut to size on top. It doesn't move

So just a case of cutting it directly to fit? What thickness ply did you use

Its basically two floating floors, tape the kingspan to itself and the walls and then use T&G OSB or just ply and screw each panel to the floor.
The weight will keep it all in place as long as you cut it remotely to size.
