Howdy folk, 

 

Just reading through the kingspan advice for insulating above a concrete slab and I make note that they suggest a batten under door transitions (understood) and toilets / stairs. 

 

As i'm doing a downstairs WC with a hidden cistern i'm just curious how folk would arrange or attach a batten in this situation. 

 

a) Running perpendicular to the toilet like a Joist. 

b) Within a notched out bit of the PIR (Perhaps a square box?)
c) Lengthways along the toilet and fixed to the wall behind the toilet lengthways?

Not seen a single video on the tinterwebs that covers this and would like to avoid a bouncy toilet. I'm all ears!

 

Cheers

Flooring chipboard or 18mm ply set into the insulation. It’s just something to spread the load and give you something to screw into. 
or a wall hung pan and you don’t need the batten under the toilet … but you would be needed under the frame unless solely supported from the wall.
