Insulated Piping From Watts Radiant

R-flex by Watts Radiant is a pre-insulated, flexible, energy-saving PEX piping system with a durable, waterproof outer cover. R-flex is used as cost-effective distribution for heating and cooling applications in schools, universities, resorts, housing developments, and much more. It 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 flexibility and light weight of R-flex make it far easier to install than rigid piping systems.

Flexible, Fast, and Easy
R-flex derives a unique benefit from the use of the polyethylene foam insulation and the double-wall outer shell; increased flexibility. This feature provides an advantage when running R-flex between buildings, around trench corners, or through wall penetrations. The ability to maintain tighter bends makes handling easier and installations quicker.

Simply dig a trench, lay down a sand foundation, and lay the R-flex in a gentle serpentine pattern. R-flex is self-compensating, eliminating the need for expensive expansion loops.

Single and Dual R-flex carrier pipe options provide greater system design flexibility and reduced installation time.

Long coil lengths minimize the need for mid-run connections translating into reduced installation costs and a reduced potential of leaks.
