Supaflu® designs, manufactures, and distributes, an exceptional chimney lining material that has passed even the most demanding UL standards in the industry.

Supaflu® is tested and listed by Warnock-Hersey to the stringent UL Standards UL-1777 and UL-103-HT, as well as the UL’s Canadian Standards ULC-S629M and ULC-S640M. These tests exposed the Supaflu® product to the most severe conditions typically associated with chimney performance. Supaflu® passed strength tests, acid absorbency and freeze/thaw tests, and exceeded 2100F in the exacting high temperature test.

Supaflu® is recognized by the International Conference of Building Officials - ICBO Report No. 3937, and by the building Officials and Code Administrators International, Inc. - BOCA Report No. 86-67.

Supaflu® is highly recommended by local building officials and insurance companies throughout North America.
