Quattro-DS (double strip) is a flexible twin-skinned stainless steel flue lining with a smooth inner wall, and a riged convoluted outer wall (to aid bending).
As the name suggests the flue liner is manufactured from two strips of raw material, the wider of the two forms the convoluted outer, whilst the inner froms the smooth inner wall. The joint or seam is construtructed using a triplelock dovetail folded seam, to make this joint extremely strong.
The system has been designed to upgrade existing chimneys which have failed, or for used to increase the performance of the flue.
Manufactured in two skins of either 316L grade (System MF5),
or two skins of 904L grade (System MF18H),
or inner skin of 904L and outer skin of 316L (System MF18M)
Comes with a range of accessories, and is available in 100mm, 125mm, 150mm, 180mm, 200mm, 250mm, 300mm, 350mm and 400mm diameters.
