Watts Radiant's R-flex is a pre-insulated, flexible, energy-saving PEX piping system with a durable, waterproof outer cover. It provides cost-effective distribution for heating, cooling, and snow melting applications in schools, universities, resorts, housing developments, and other residential facilities.
R-flex consists of a long-lasting PEX carrier pipe or pipes surrounded by thick insulation layers, all contained in a unique double-wall outer casing for maximum protection. The use of the polyethylene foam insulation and the double-wall outer shell makes R-flex very flexible. Its flexibility, combined with its light weight, make R-flex far easier to install than rigid piping systems.
