Thermal Tech Insulation
The DuraPlus Chimney outer wall is either stainless steel or galvanized steel and inner walls are made of 430 stainless steel and encase the ceramic refractory blanket and air space. The DuraPlus system locks tightly with a precision twist-lock connection. The ceramic blanket insulation is held secure into position, eliminating hot spots common with loose-fill type insulations.

DuraPlus end-ring liner suspension at each joint flexes to allow liner to expand lengthwise when hot.
