Hello,
Planning to do my own hydronic radiant system.
I already have a 3/4″ OSB subfloor nailed/glued. I wanted to install over the OSB subfloor either some XPS or EPS foam panels and cut grooves with a router, install sheets of aluminums and run my PEX tubing.
I like the premade Roth radiant panels and wanted to copy their design, their panels have EPS foam with a compressive strength of 90 PSI.
I am planning to have this installed in this order: OSB/foam/Engineered floating floor.
I want to avoid using sleepers because it is just too expensive right now.
What would be the ideal PSI for that project? I cant really find anything rated over 20 PSI.
Thanks!
