The APX1250 from Everhot is a 500ft roll of 1/2” PEX-AL-PEX pipe. It's ideal for radiant floor heating, radiant heating system, and snow melting applications. PEX tubing is incredibly lightweight and flexible, unlike Copper, CPVC, Iron and etc. PEX-AL-PEX is made of a layer of aluminum sandwiched in between two layers of PEX, which allows the tube to retain its shape and endure high pressure.
