Is polythene needed with underfloor heating?
Hello, I'm wondering if someone can help. I’m a total novice so any help greatly appreciated.
I have electric underfloor heating and I'm replacing the carpet in the bedroom, which has a concrete floor, with laminate.
Do i need to put a polythene layer down before the underlay?
One Answer
No, is the short answer.
More important is to ensure that you use carpet and underlay with a combined TOG rating of no more than 2.5, otherwise you will over-insulate the system and lose efficiency.
