HeatShield’s hybrid “Cerfractory” technology combines the strength of a high-fired ceramic with the heat resistance of high temperature refractory cements. HeatShield Cerfractory Flue Sealant when used with CeCure Sleeve is certified to UL 1777- Standard for Chimney Liners by Intertek. HeatShield has been tested to ASTM C199 Standard Pier Test for Refractory Mortars and is rated “Super-Duty”. It exceeds both IRC and NFPA code requirements, which specify medium-duty.

It can be used to reline masonry chimneys with the addition of the CeCure Sleeve, provided the HeatShield Cerfractory Flue Sealant mix plus the CeCure Sleeve achieve a total minimum of ½ inch lining material thickness. In suitable masonry chimneys, HeatShield Cerfractory Flue Sealant may also be used to repair missing or defective mortar joints, or it can be “slip cast” over the entire surface at an average thickness of 3/16 inch (1/8” min.). HeatShield Cerfractory Flue Sealant with CeCure Sleeve is considered an “all fuel” chimney liner. For use only with residential chimneys that service Category I gas-fired (natural gas or propane), Type L vented oil-fired and solid-fuel-fired appliances.
