Technology & Testing

Cerfractory® Technology

Developed in Europe over 20 years ago, HeatShield's® proprietary Cerfractory® technology is a hybrid ceramic/refractory material.

It combines the strength of a high fired ceramic with the heat resistance of high temperature refractory cement.

HeatShield® Cerfractory® Flue Sealant is supplied as a dry powder that is mixed with tap water immediately before use. Once applied, the product air cures to a hard ceramic like material that is moisture and corrosion resistant.

The unique Cerfractory® technology maintains its physical shape and chemical properties even when subjected to high temperatures.


Chimney Liner Testing

Chimney Liner Performance Testing

Underwriters Laboratory (UL) has developed the UL 1777 Standard for Chimney Liners to investigate the performance of chimney liner systems. By UL’s definition, a chimney liner is a system to be used in conjunction with a chimney that is constructed from metallic or nonmetallic materials that are factory made or mixed, and that is assembled in the field to form a complete, functional means for conveying products of combustion to the outside.

The UL 1777 testing was performed on the HeatShield® Cerfractory® Flue Sealant and CeCure Sleeve Liner Repair System at Intertek’s Warnock Hersey Hearth Products Lab in Middleton, Wisconsin. The following is a brief overview of this testing.

[+] (Step 1) Construction of Test Chimney

[+] (Step 2) HeatShield® Cerfractory® CeCure Sleeve Installation

[+] (Step 3) Flue Gas Temperature Tests - 1000°F, 1400°F, 2100°F

[+] (Step 4) Swep Test

[+] (Step 5) Strength Test

[+] (Step 6) Resistance to Action of Acid Test

[+] (Step 7) Freeze/Thaw Test


UL Standard 1777 Test Findings

The HeatShield® Cerfractory® Flue Sealant/CeCure Sleeve Liner System was found to be compliant with all aspects of the UL 1777 performance tests for Chimney Liner Systems.

The product is listed to UL Standard 1777 with zero clearance to combustibles by ETL-Intertek under the Warnock Hersey label as a chimney liner system for masonry chimneys that service most gas-fired, oil-fired, and solid-fuel-fired residential-type appliances.

In addition to HeatShield’s® listing to UL 1777, the product is Certified by ETL-Intertek to conform to the applicable standard through a rigorous program of ongoing testing and factory inspections.

The HeatShield® Cerfractory® Flue Sealant/CeCure Sleeve Liner System is available through a network of factory trained, independent installers.


Chimney Repair Testing

Chimney Repair Performance Testing

Various ASTM and other performance tests were conducted at Intertek Testing and Orton Materials Testing and Research Center to investigate HeatShield's effectiveness for restoring damaged and deteriorated fireclay lined flues in masonry chimneys.

An outline of investigation was developed and followed using various ASTM tests and the UL 1777 Standard for Chimney Liners as a guideline. Because there are no published listings or listing requirements for clay flue tile or repair systems, it is important that any prescribed remedies be tested within the systems they are intended to repair.

[+] (Step 1) Construction of Test Chimney

[+] (Step 2) HeatShield® Cerfractory® Application

[+] (Step 3) Flue Gas Temperature Tests - 1000°F, 1400°F, 2100°F

[+] (Step 4) Swep Test

[+] (Step 5) Smoke Leakage Test

[+] (Step 6) Refractoriness of Mortar Test

[+] (Step 7) Thermal Resistance Test


Chimney Repair Performance Test Findings

The HeatShield® Cerfractory® Flue Sealant was found to be compliant with all aspects of this outline of investigation for chimney repair and proven effective for restoring the original integrity of a chimneys ability to contain and convey the products of combustion to the outside.

In addition to the HeatShield®/CeCure Sleeve product listing to UL 1777, HeatShield® Cerfractory® Flue Sealant is effective for repair of masonry chimneys that service most gas-fired, oil-fired, and solid-fuel-fired residential-type appliances.

The HeatShield® Cerfractory® Flue Sealant and CeCure Sleeve Liner System is available through a network of factory trained, independent installers.
