EnviroCure®-Felt
US Patent No. 12,467,573
Styrene Odor Mitigation. The Only Liner of Its Kind.
EnviroCure®-Felt, is a patented, and game-changing, CIPP liner developed by United Felts, a division of Vortex. It was designed to significantly reduce styrene emissions while maintaining the strength of traditional liners. This liner features a unique styrene impermeable polymer coating that effectively contains styrene emissions to less than 1 part per million at the job site, offering a safer option to styrene free liners that lose strength.
Third-party job-site testing shows that EnviroCure-Felt consistently exceeds regulatory standards for styrene emissions. This makes it an ideal choice for projects requiring stringent environmental compliance without compromising on quality and ease of installation.
