Waste of money even the reps & manufactures state it’s not worth using insulation Boards on wooden floors only need them on concrete floors.
You won’t get a return on investment for years. The savings on a concrete floor, pay for the boards after 2 years. So what’s the stat for wood which is a good insulator in itself it’s gonna be more like 10 years
Which is why you don’t need to use them waste of time and cash
You could even just use a product like warmup dcm pro for speed and less height which would also require no screed and is self adhesive
