A radiant floor heating solution leveraging Polyethylene of Raised Temperature Resistance (PE-RT) technology from The Dow Chemical Company (Dow) is the hy-PE-RTube™. It is produced using DOWLEX™ 2344 resin from Dow. The solution can help greatly improve ease of installation with its flexible design, which allows the pipe to resist recoil and lay flat when installed. According to the manufacturer, hy-PE-RTube offers increased flow properties and excellent high-temperature, corrosion, and stress-crack resistance. The product can be used for other hydronic heating and cooling applications aside from radiant floor heating, such as snow melt applications and turf conditioning. hy-PE-RTube consists of five layers — a central ethylene vinyl alcohol polymer (EVOH) layer between a layer of adhesive and DOWLEX 2344 each on both sides — helping reduce noise when in use. The outer layer of DOWLEX 2344 offers enhanced protection against oxidation due to piping permeation, further safeguarding the radiant heating system.
