SuperPro Chimney features 304-alloy stainless steel for both its inner and outer liner. SuperPro also features mineral wool insulation. This insulation is made for amazing performance and dramatically reduces chemically active ingredients. It provides a thermal delay that resists and contains surges of heat, keeping the outer liner cooler.
SuperPro couplers are embossed to reduce moisture penetration. This greatly increases the longevity of the chimney. SuperPro features twist-lock connections but locking bands are recommended at each joint for extra security. SuperPro has been tested. The manufacturer approves its use for wood, oil, coal and gas.
