Flexiwall flexible chimney liner is a Solid fuel/ Multi fuel Flexible Chimney Liner used to line an existing brick or masonry stack.

904/904 is the highest quality chimney liner available.

Flexiwall chimney liners are all of stainless steel twin-lined grade 1 quality and produced to the highest of standards. The liners are designed to withstand high temperatures and have a good resistance to corrosion.

Flexiwall chimney liners flexibility allows it to be handled and installed with a minimum curvature radii whilst avoiding any damage to the inside of the liner, in other words it is a very flexible flue liner. When installing the chimney liner, please note that the arrows marked on the liner need to face up the chimney, indicating the direction of the flue gases. Incorrect installation can result in a faster build up of soot deposits and a greater chance of a chimney fire. The inner wall is of smooth bore construction giving extremely low resistence to the flue gas flow. The outer wall has a convoluted profile with a crimp and locked seam. The two walls are seamed together throughout the length to ensure its stability and integrity.
