Wood Chimney

Simpson Duravent’s HTC wood chimney is engineered to meet the demands of ULCS629 (Underwriters Laboratory Canada Standard for wood stove chimneys). Our new Thermal Tech II insulation encased between two stainless steel walls, offers the optimum in safety and performance by eliminating hot spots common with loose-fill insulation. In the event of a creosote fire, compressible blanket insulation permits the chimney to expand in a radial direction. This eliminates buckling and loss of structural integrity associated with solid pack chimneys. A wide range of components are available to make your installation safe, convenient, and efficient. Simpson Dura-vent chimney comes with a limited lifetime warranty.
