Hi,
I live in a 4 year old flat with underfloor heating. About 2 years ago I noticed kind popping noise coming from different parts of floor whe ufh is warming up and cooling down. The noise is so loud that it wakes me up at night. I thought that it was air trapped in the system but tried few tricks to remove it and nothing worked. I am pretty sure now it is not the air but rather insulation of the pipes. Floor construction looks like: concrete screed, thin insulation matt, about 1 inch thick pink foam with water pipes inside it, chipboard on top, thin insulation matt, carpet.
Is this proper floor construction for such system? Can this noise be caused by insulation foam and is it normal? Are there any standards covering this regarding noise level and its intensity?
Can anyone have help with the answers?
