I am installing a radiant floor using some aluminum track plates in my home. It is a rather challenging install, given the 16" OC joists are not straight forward bays. There are LVL's (single and double) run mid-span between joists for floor strengthening, other areas where additional blocking has been added, etc.
I have all my track plates installed, and have been pulling 1/2" Uponor HePex, however it is taking a beating, as I am working with tight angles and narrow spaces that are difficult to work within, and pushing the limits for bending radius, etc. I have about 400' between two runs.
Given all the snaking I've had to do with the tubing, the far end has now lost all the lettering, and I can only assume that I've damaged the O2 barrier. In hindsight, I think a little more care would help, but not dramatically reduce the rubbing during installation.
My understanding is that there is a thin PE layer over the EVOH oxygen barrier. How do you know when you have worn down to or through the EVOH?
My only thoughts at this point are to cut and re-start, doing short 20-30' sections joined by couplings, though I'm not excited about that.
Interested to hear thoughts. This is some of the more challenging space:
