With its revolutionary design and easy application, Furanflex has deservingly won several awards.

Furanflex has won several awards and with good reason. It’s guaranteed for 25 years and is especially good when faced with an unusual shaped chimney or very wide flues. Furanflex will mould itself to completely fill a square flue thus maximizing its cross sectional area.

The liners come in every shape and size and are made of a glass fibre reinforced thermosetting resin composite. Once set, Furanflex is stronger than steel and unlike steel it will not corrode. It is highly heat resistant to 400 degrees centigrade, only 3mm thick and there are no joints, thus ensuring a gas tight finish (certified to 200 pascals) making Furanflex not only a fantastic product but a very safe one too.

Installation is very straightforward; the job can nearly always be done without any demolition or disruption to your building – you can watch a typical installation, here.
