PEX tubing must be secured prior to the concrete pour during in-slab radiant heat installations. The most popular way to do this is with zip ties. Spaced 24 to 32 inches apart with additional ties at each bend, zip ties are a cost-effective method.
A stapler can speed up the process and save valuable time for contractors. SupplyHouse.com carries PEX staplers and staples from Uponor, Malco, and Peter Mangone that connect PEX to foam board insulation beneath a concrete slab.
