What makes Onix™ perfect for radiant heat and snow melting applications. Cross-linked Durel EPDM is extruded into a tube then wrapped with an AlumaShield barrier and a second layer of Durel EPDM. This composite tube is reinforced with 1000 denier aramid cord, the same incredibly tough and heat resistant material used to make fire- and bulletproof shields. A third and final outer jacket of EPDM is applied. The result is a durable, flexible tubing formed of five heat and age resistant materials, proven in tens of thousands of installations over the years.
One of the best features of our Onix tubing is its aluminum barrier layer, AlumaShield™. Unlike plastic barriers, AlumaShield is unaffected by sunlight, UV radiation from fluorescent lamps, moisture, or elevated temperatures. Due to its placement inside the tube, the AlumaShield barrier can't be scraped off or damaged by typical job site abuse.
Onix is the product that can be installed with lifelong confidence in blazing heat and sunlight, or in Arctic frost and shadows. Used for commercial snow melting, space heating, residential staple-up and supply/return lines, you'll find Onix installed in thousands of quality projects every year.
