Viega’s ProRadiant insulated PEX barrier piping system for its snow-melting system features insulation which results in a reduction in heat loss over competitive products, the company states. The “smart” membrane between the outer casing and insulation keeps operating performance high throughout the pipe’s service life. The bonded system eliminates risk of water penetration and no special considerations for thermal expansion are required. The polyethylene (LDPE) jacket resists any impact or blows incurred during installation or transportation. The piping requires no special tools for assembly and is available in long coils or custom coil lengths.
