Flexible Liner

Flexible Flue Liner is constructed from Stainless Steel. The lining is made of two thin layers, an inner and an outer layer sandwiched together.

There is a choice of two grades of liner 316 grade and 904 grade. Flexible lining offers a fast and efficient method of re-lining an existing chimney.

The minimum diameter of a flexible flue liner that can be installed on a wood-burning or multi-fuel stove is 150mm. The only exception is where a Defra Exempt stove is installed. With a Defra Exempt stove you can use a flue diameter with a minimum diameter of 125mm.

The flexible flue liner is attached to the single skin flue pipe that comes off the top of the stove with an adaptor (adaptor to flex). A cowl must be added to the top of the chimney.

The flex liner must be secured in place at the top and bottom. The liner can be secured at the top of the chimney stack with a closing plate and top fixing clamp, or attached directly onto the cowl with securing clamps.
