Garage floor

[philz]

I am in the process of a garage conversion and need advice. The floor slopes from back to front i am using 50mm kingspan and timber battens. Can anyone explain how i overcome the slope. (will be using t&g chip board on top.

You'll need to use tapered timber battens (if its not too much of slope?) which you can get done at a local timbermill or you'll need to use slightly diminishing sized battens/joists as you work accross the floor, have buiding control approved your 50mm Kingspan? sounds way too thin to me.

You fix horizontal timber to the side walls and hang the joists off these on hangers. No need to taper any timbers

Good thinking, I assumed he was fixing his battens directly to the top of the slab!

Thanks woody, BCO have approved the 50mm kingspan although they have said they want 350mm loft insulation.
