PAP vs pex in ultra-fin system

JROLDTIMER Member Posts: 5
I  am installing a ultra-fin system. I am concerned about expansion noises. Is ultra-fin compatable with PAP ?

    I have used PAP with Ultra-Fin

    I believe they recommend 1/2, and while a lot guys poo-poo the product, I found it works well. The btu's get pulled out of the tubing (similar to plates) a lot better than bare tubing. They show joist space heating systems, but you can use more tubing and fins and still lower the supply temps, etc. Dangle it closer to the floor, insulate under.
