The Radiant Rollout™ mat is a custom-designed, prefabricated, pre-pressurized network of the company’s cross-linked polyethylene (PEX-a) tubing deigned for faster, more consistent installations for large commercial radiant heating and cooling applications. The mat consists of Wirsbo hePEX™ (oxygen barrier) or AquaPEX® (non-barrier) PEX-a tubing connected with ProPEX® engineered plastic (EP) fittings, which are safe for burial in the slab and offer fast onsite customization when necessary. — Uponor
