PERT EVOH is a strong pipe which are widely used in floor heating. PERT, which stands for polyethylene with raised temperature, is the base material used to manufacture flexible plastic piping that has become popular for in-floor radiant heat tubing. PERT is corrosion resistant, flexible, durable, and efficient at conducting heat - making it almost an ideal tubing material.
EVOH stands for Ethylene-Vinyl Alcohol Copolymer. It is a plastic film material that offers an exceptionally strong oxygen barrier. The molecular structure and production process of EVOH makes it hundreds of times better than other plastics at preventing oxygen permeation. This unique oxygen-blocking capability is what makes EVOH such an important innovation for PEX and PERT pipes used in radiant heating systems.
In practical terms, this EVOH innovation translates to unprecedented longevity and near "zero failure" expectations from modern PERT piping. Installing with a built-in EVOH barrier provides peace of mind by essentially guaranteeing the tubing itself will not encounter issues like pinhole leaks for 50+ years. This allows the tubing to last as long as the house itself in nearly all cases.
Beyond amazing durability, the oxygen resistance also enhances overall heating system efficiency and reliability. Preventing metal component corrosion enables boilers, manifold, and pumps to achieve their designed lifespans. This lets homeowners avoid expensive warranty replacements. Further, minimizing oxidation inside PERT tubes keeps heat transfer capabilities at factory optimal levels for decades rather than degrading over time like standard PERT.
In closing, PERT tubing upgraded with an EVOH oxygen barrier layer represents one of the most meaningful advancements in modern in-floor heating technology. This thin plastic film innovation enables a basically "leakproof forever" piping material driving today's most reliable and highest performing radiant systems.
