DuraPlus HTC is a double-wall, all-fuel chimney system for Canada for use with wood stoves, fireplaces, and appliances using wood, oil, gas or coal. The insulation maintains a barrier that will not shift or settle and the wall keeps the exterior cool, while ensuring high temperatures for optimum draft performance on the inside.
