Agreed. When I got the quote I told them I wanted the floor left open, they said no problem then built this. He said the floor doesn't really need insulated if you'd believe that. Does 20mm celotex have a high enough compressive strength for the floor? I only really have 30mm from floor to...

Ok so I don't think I have the height to install any over floor insulation actually. There are 2 ceiling to floor windows with very little clearance from the floor to bottom of the pane. Here's some pictures: And the door: Here's pictures of the floor itself: Is my only option...

I was hoping to use it as an office space, I probably should have done some more research before purchasing. Oh well, big coat it is. Just so I'm clear here will I put batons down to what ever height of insulation I can fit in, celotex and tape, then screw plywood to batons? What thickness of...

Yeah I should do, I'll have to measure it later. Will I have problems with moisture under the floor if I just lay celotex down? Would 25mm even achieve much?

Yeah a shed more or less. I'm insulating the walls and roof myself but I can't get under the floor. The way it's built the walls are sitting on the floor. No it's not vented either should it be? The roof is vented with a 50mm gap above the insulation.

I've had a garden room built but no insulation was installed under the floor. It's sitting on blocks but not high enough for me to install PIR underneath. The floor is 20mm thick timber boards on 5 inch joists. Is there any type of thin insulation I could put above the floor before installing...
