Not all chimneys are the same shape or design and as a result standard lining products cannot be used. FuranFlex has been developed to mould to the shape and run of the flue and can also be installed in any diameter and any length without joints in the lining making it completely gas tight.

FuranFlex technology is made from a glass fibre reinforced thermosetting resin composite. This means when installed FuranFlex liners are as strong as steel and also resists corrosion better than steel chimney liners.
