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.


When the area within the chimney is limited, the Guardian 3/4” minimum liner thickness allows you to line the chimney. The Guardian 3/4” standard ensures all installations will meet zero-clearance specifications. Guardian forms are meant to be used with assembled spacer (As shown in the photo below on the left). Refer to our website for more information.
