Advanced design for superior performance and safety The innovative SM large-diameter chimney from Security Chimneys™ features 2” of high-temperature blanket material insulation – twice as thick as the competition – for the highest level of performance and safety. This enhanced insulation keeps the flue gases hotter for a better draft in masonry fireplaces. Despite the hotter internal temperature, the exterior casing runs at cooler, safer temperatures. As a result, the SM chimney only requires a 1” clearance to combustible materials. So, chase dimensions are kept to a practical size. To ensure reliable performance, the SM chimney also features solid steel couplers, rather than leaving the insulation exposed between length connections like other chimneys. This helps protect insulation from water infiltration and maintains insulating properties.
