I have looked through the available threads concerning this topic already but they date back a few years and do not address my concern exactly.
I am about to buy a semi-solid tongue-in-groove ash floor for an extension with underfloor heating (200mm of insulation underneath). All the information I have found here and online (scattered and sparce) points to a floating floor which suits me fine. The issues arise with regard to the underlay. My concern is that the underlay would end up as an insulator rather than a conductor of heat and reduce the effectiveness of the heating. I know that the wood itself is not as good a conductor as stone or ceramic but should I be trying to avoid any additional insulators? From what I can gather, the foam underlay gives the floor a good feel underfoot and can eliminate air pockets were the floor to be floated without the underlay. If someone could suggest a suitable underlay I would appreciate it. I know that elasticon make a product called 'lock' which is for ufh floors but it seems to be aimed at click together floors rather that standard tongue-in-groove. Also, one floor shop gave me a sample of the underlay they use. It is 2 - 3 mm white foam but I have no idea whether it is a conductor or insulator. Lastly, should I also consider putting a moisture barrier over the concrete first (another heating hurdle?)
Thanks.
