Questions & Answers
Question:
Can I overlay Celotex with underfloor electric heating ?
Answer:
Good morning to you. From my experience after speaking with customers and suppliers alike, I would not recommend direct contact with the Celotex boards, a common approach would be to screed over the Celotex first, then put the underfloor heating over the top. I hope this helps.
