Dura Flue is the only stainless steel flexible chimney liner on the UK market that can be fitted in either direction. This is due to the patented manufacturing process, this not only allows for multi-directional use but also makes it extremely difficult for corrosion to set in unlike other traditional flexible flues.
Dura Flue is made from 2 separate sheets of stainless steel:
The Outer: The outer skin of Dura Flue is a pre-profiled ribbon of stainless steel, with deep, close-together waves that create an extremely hard and protective exterior for the flue, like a shell. When your chimney liner is dragged down a brick flue it will undoubtedly be pulled and hit against the brickwork, because the outer/shell is a separate sheet (and not 1 or 2 pieces folded together) it protects the smooth inner from damage. It also makes it less likely that the flue in general will be damaged or compromised before installation compared to other flues that are soft and can be damaged as easily as being knocked in the back of a van.
The Inner: The Inner skin of Dura Flue is a pre-profiled ribbon of stainless steel, which has been made with a fine special oil spray to create a smooth inner surface. Unlike other flues, our inner surface of steel has not been folded or scratched in production and has not been compromised in any way. It is locked to the outer skin purely with pressure using a patented technique. This means that Dura Flue essentially has a fresh un compromised inner surface for the flue gasses to pass through making it almost impossible for corrosion to set in.
There are no internal flaps, folds or lips on the inside of Dura Flue it is the only chimney liner on the UK market to have this unique feature. Traditional flue liners with multi-directional arrows and flaps/folds inside damage easily, can come apart on installation and could splay or come apart internally once fitted, which you will not normally see unless your installer or chimney sweep does a camera inspection for you.
