Hello!
I have just installed hydronic underfloor heating in plates for floor joists. These plates are large (double 20mm channels) and are unsupported except at the edges on floor joists with 60 cm spacing. Most of the plate just sits directly on the insulation.
Before I lay the floor again (wooden floor), I'm wondering if I should put something like felt paper or something between the plates and the floor to minimize the risk of the plates rattling against the floor? Or does felt paper insulate too much?
I find very little information about this type of underfloor heating... and before you criticize the choice of underfloor heating, it was the only type that doesn't add centimeters on top of the joists, so it was this or no underfloor heating.
Felt paper or not? Or something better?
Here are the plates:
