Blimey that means 20mm board for the pipe, 18mm for the chip, 6mm for the ply, then the tiles that's 45mm!! That's no small increase in floor height!!
Yeah that's the one, have a profile of about 18-20mm. My guess is you'd need 10mm ply on top then thin screed, then tile. So approx 30mm of floor.
Hi I am doing a kitchen diner knock through and I want underfloor heating with Karndean tiles. I would like a wet system on my existing combi...
