Onix Tubing represents the pinnacle of underfloor heat engineering. Made from an EDPM based aramid fiber, onix tubing does not expand and contract like normal PEX tubing, allowing it to stay in contact with its heating surface at all times. Easy to install at any temperature, Onix tubing can reduce installation times by up to 50%, and will ensure that your radiant heating system lasts for decades.
