Reliable HeatShield® Chimney Lining Services in Portland, 97212, and 97213

We recently completed our first project using the HeatShield® Cerfractory® Flue Sealant system—and we’re impressed.

This innovative “cerfractory” blend combines the strength of ceramic with the heat resistance of high-temperature refractory cement, giving it the best of both worlds. The system is UL 1777 certified for chimney re-lining and has been independently tested to exceed building code requirements (including those set by the IRC and NFPA). In fact, it earned a “Super-Duty” rating in ASTM testing—far beyond the “medium-duty” minimum.

Take a look at some photos from the project—we’re excited to bring this powerful new option to more of our customers!
