Underfloor heating and Karndean

andy_from_embsay

We're having electric underfloor heating (mat) in our bathroom, and we're also having Karndean flooring - but I'm not sure if the two are compatible.

The electric floor goes on the chipboard, then you screed on top of it. But the Karndean people say you need to put plywood on top of the chipboard - so do we put chipboard, then heating, then screed then Karndean or something else?

Thanks

We were considering ceramic tiles with underfloor heating, but have decided just to have Karndean with out underfloor heating as it really isn't that cold under foot....

Can I suggest you get the cable rather than mat version of the floor laid? It's actually easier to fit and is usually recommended in bathrooms where you can lay your own pattern around the loo, sink pedestal etc more accurately than having to cut up the matting. When you cut the mat, you still musn't cut the heating element so it's more of a fiddle fitting it (imho).
