ᐅ Which Flooring Is Suitable for Underfloor Heating?

Hello everyone, we plan to install tiles and hardwood flooring in our future house, either by ourselves or by professionals. Tiles will be laid throughout the entire ground floor, except for the study room, and upstairs in the bathroom and hallway. The other rooms will have wood floors, which I intend to install myself. We were considering engineered hardwood flooring and initially thought it had to be fully glued down. However, a tennis friend recently told me that this is no longer necessarily required. He knows quite a bit about construction. Floating installation is also possible if the appropriate impact sound insulation is used. His daughter’s floor was installed this way, and it did not affect the performance of the underfloor heating. Several flooring dealers have confirmed this to me as well. The only downside is that transition strips need to be used. Some argue that the flooring must be glued down. Impact noise insulation is a minor concern for us. No one wears outdoor shoes indoors, at least not in the bedrooms and guest rooms. Also, the possibility of sanding the floor later is not an issue. I’ve also read about someone using 15mm (0.6 inches) thick solid wood floorboards, which were of course glued down. Does anyone have experience with this?
