Hi,

I am insulating my shed to use as a workspace.

I bought a load of 50mm Kingspan insulation boards for the walls. I
used the left over on the floor and covered it with 18mm chipboard,
but Its still predictably cold.

I have an opportunity to buy some cheap electric underfloor mat
heating.

What I want to do is take up the chipboard, put the heating mat on top
of Kingspan, then put some cheap tiles on top.

Would this be ok ? ie. is it safe to lie the heating mat straight on
top of the kingspan ?

Thanks in advance,

Matt
