DURA FLUE TRIPLE WALL FLUE SYSTEM for use in modern, room-sealed stoves and replaces using wood and pellet. Designed and tested in cooperation with renowned stoves manufacturers, our D3W appears as a perfect solution for passive houses providing superior thermal quality, safety and comfort.

Energy-saving and ecological

DURA FLUE TRIPLE WALL FLUE SYSTEM design allows to heat the fresh air supplied to the stove through the air gap between the stainless steel outer wall and insulated inner wall which optimises the appliance efficiency by 10% comparing to a traditional twin wall insulated flue system with combustion air supplied from the room.

Safety of use

DURA FLUE TRIPLE WALL FLUE SYSTEM provides a natural safety barrier, in case of a soot fire in the flue, through the air gap encircling insulated inner liner. It works with a room-sealed stove and prevents backdraught process by means of the air supply channel eliminating the risk of intoxication.
