Can floor be laid on top of concrete? There will be no regulated heat in the enclosed patio and could get down to 32-40 degrees in the winter.

Hello Laura - thank you for your inquiry. The ProCore Plus can be installed on top of a concrete slab - however, the optimal service temperature is between 40° - 90°. Temperatures below that will risk product failure as well as a voided product warranty. Hope this helps answer your questions. Thank You -
