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 development of the Guardian Chimney Liner® is the culmination of 30 years of field experience by the Firesafe Corporation: a company that has installed thousands of cast-in-place chimney liners, in combination with a team of ceramic engineers. The practical applications from thousands of installations united with scientific research and development led to the production of the Guardian Chimney Liner®.

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.

The proprietary formula of the Guardian Chimney Liner® material provides an insulating, refractory compound that is the only chimney liner approved for zero-clearance specifications with 3/4" liner thickness. This break-through approval is especially critical when the available flue area will only allow a 3/4" liner. Consequently, when the area within the chimney is limited, the Guardian 3/4" minimum liner thickness allows you to line the chimney when our competitors cannot legally do so, since their minimum poured liner thickness is 1" to 1 ½". Furthermore, the Guardian 3/4" standard ensures all installations will meet zero-clearance specifications. The National Fire Protection Agency is strongly considering a mandate requiring that all chimney restoration methods comply with zero-clearance specifications. No problem!


So impressive is the Guardian Chimney Liner® that it is backed by a lifetime guarantee. Please see your chimney restoration professional, or contact us for details.
