Underfloor heating questions

[Dan Ryan]

Thanks I've heard 25-30mm. That 5mm will make quite a difference, with the transition to the future carpeted room.10mm underlay and 12mm carpet. Ive then got 8mm to make up with carpet shims. Probably not a great finish as you'll see the slope and trip on it. Other option would be to screed the carpeted room's floor, but that will run into a small fortune I don't have.

you could possibly build up the carpeted area on the green minerals boards the use for lamnate flooring lay your underlay on that then your carpet if need be double layer it that between 7-9 mm thick or screw down 12mm marine plywood down to raise the floor up that would be cheaper the levelling screed as that come in 8 x 4 sheets

Just feather a gentle ramp 50cm out of the door with half a bag of tile adhesive, 8mm over 50cm is nothing..
