Hi it was 18mm birch ply b/bb grade finished both sides with osmo.
I ask because I’m quoting for a lot of birch ply cabinetry in a house with underfloor heating.
Hi recently I had some floor level birch ply cabinet doors warp badly. The room had underfloor heating turned up quite high.
I made replacements but these warped as well.
Have other people had similar effects from underfloor heating and birch ply?
Thanks
