A 150mm twin wall adaptor is a fitting that connects a single-wall flue pipe (like the vitreous enamel flue pipe) to a twin-wall flue system. Twin-wall flues are insulated and typically used when there's no existing chimney stack or when the flue needs to be run close to combustible materials.
It bridges the gap between a standard single-wall flue pipe and a twin-wall flue system, allowing for a smooth transition and safe operation.
Outer skin is made from 304 grade stainless steel. Inner skin is made from 316 grade stainless steel. Insulation is compressed Rockwool.
