M&G DuraVent DuraPlus

DuraPlus is designed to stay cool on the outside, to provide a hot draft on the inside, to boost stove efficiency, and to provide a fire-safe design that protects both the chimney and the building.

This triple-wall chimney features two insulating layers (ceramic blanket, plus air space0.  The ceramic blanket insulation is held securely in position, eliminating hot spots common with loose-fill type insulations.  In the event of a creosote fire, the compressible blanket insulation permits the chimney liner to expand outwardly in a radial direction.
