The revolutionary Guardian Chimney Liner is the safest and most effective system for relining masonry chimneys. Using the cast-in-place technique, the Guardian chimney liner is not just a chimney liner, but a complete restoration process of the chimney structure. The Guardian Chimney Liner is tested and listed to UL 1777 by accredited laboratory, Guardian Fire Testing Laboratory, Inc. Additionally, the Guardian Chimney Liner is the only chimney liner in the United States to be certified by the International Code Council Evaluation Services (Report # ESR-2672) as compliant with the 2006 International Building Code, 2006 International Residential Code, and the 2006 International Mechanical Code.
