Hello, I have a system that is suspended under the sub-floor with staples. Then the tubing was covered in a 2' strip of plastic so the foam didn't touch. That was just a precaution wasn't sure if the foam chemicals would react, so that's just a barrier. Then the spray foam was installed. These are scissor trusses. Two zones and the floor is heating great. Just wondering about efficiency and if the system will function as it should. Heating with a A.O. Smith Vertex LP. I've had a person look at it and they said you have to have a 2" air gap and the aluminium track. Is that correct? Thanks for your help.
