    Why is this architect saying watch out for engineered wood floors that may not be compatible with underfloor heating?

    During my reading of the UFH installation guidelines published by The Solid Wood Flooring Company I came to the section on drying times for screed and was gobsmacked at the recommended waiting time for a screed to dry out - down to a moisture content of less than 1.8%. I haven't decided yet on...

    Why is this architect saying watch out for engineered wood floors that may not be compatible with underfloor heating?

    Thank you for the reading reference - quite dense and there's a lot of it but the content looks as if it will address my concerns. Good point about checking with the flooring supplier about compatability of their product with the kind of ufh I will be installing.

    Why is this architect saying watch out for engineered wood floors that may not be compatible with underfloor heating?

    Hello Comrades - Preamble first: my contractor has fitted the joists (over a layer of DPM in a tanked basement), fitted the 90mm PIR insulation between the joists (the insulation sits on battens fixed to the joists), and laid 18mm flooring chipboard. The ufh wil be installed late February: water...

    Chipboard laid over wet underfloor heating pipes?

    As I understand it, the clips are barbed and designed to go one way but not another. Can the screed exert a particular pressure that over time loosens the barbs and force them upwards. Or maybe even a chemical reaction that degrades the hole surfaces made by the barbs fitted to the insulation...

    Chipboard laid over wet underfloor heating pipes?

    In terms of clipping to the insulation I would have thought that if I use a liquid screed, piercing the Visqueen with barbed staples would negate its function as a vapour barrier. I could be wrong about that.

    Chipboard laid over wet underfloor heating pipes?

    Hello Mr Chibs - Actually it's a cellar space I'm going to be tanking, so the DPM has to be laid over the solum (Scottish term for the ground the property is built on), and then the hardcore over that. Agree w. the sand blinding. Your specs for hardcore + sand binding sound right. I have a...

    Chipboard laid over wet underfloor heating pipes?

    I'm about to gut 46 sq. mts of basement and then tank it. After that I want to install wet underfloor heating but the contractor's idea of how to do the build-up for the UFH does not seem sensible. So far he has been v. helpful, but advice/guidance from a wiser head that would get us both on...
