My mate send me this, can you answer his question lads? Sorry for the intrusion but Looking for some advice please on wooden flooring please? We are thinking of fitting 18mm solid wood flooring with fibre board underlay and possibly a damp membrane onto a screened floor with underfloor heating. What we are wondering is do you think the wood with the underlay will Be too thick and also is it necessary to use the damp proof membrane as its going to be in our hall? Would appreciate any advice if you don't mind thankyou. Hope everything is ok there. Cheers Chris
personally would NEVER EVER fit solid on-top of any ufh... eng. is the only option...! also don't think the fibre board is compatible with ufh...
I wouldn't be putting solid down over a ufh myself but each to their own. As stated above tho, eng is the way fwd!!
Daz, tell him: To use engineered wood and glue it down rather than float it for better heat transfer. Make sure the UFH is fully commissioned/tested before installation. Make sure of the temperature range and that the heat is only increased gradually after installation.
pretty sure most eng. wood flooring is compatible with ufh - have carbon mat system in my living room, nice & toasty on the feet this time of year... as advised above if going onto 'wet' ufh then fully bond with suitable & appropriate adhesive for best results
Hi Chris, Unfortunately you will be making a massive mistake, firstly by fitting a solid wood floor on underlay and secondly fitting a solid wood floor onto underfloor heating. Solid wood has to be nailed or glued to the subfloor using the correct nail gun (power nailer). This should be laid with barbed nails. This is because each plank will try and move individually. If the subfloor is concrete then you should use a DPM then an adhesive that is flexible. You are well advised not to use this method on top of underfloor heating with a solid floor. I would recommend a multiply floor which has a layer of ply with a thick veneer on top. The ply makes the flooring very stable and less prone to movement. This can be glued down if the sub floor is concrete, nailed down, or if the subfloor is made from timber. In your case I would recommend floating the wood flooring on top of an underlay. The underlay should be as thin as possible (2-3mm) to let the heat through. If you have a concrete sub floor then use an underlay that has a plastic DPM (damp proof membrane) built in.
