"Revolution in the field of chimney lining"
(Composite International)

What is FuranFlex?
FuranFlex® is the only method, by which chimneys of any shape, dimension and length can be lined with joint-free airtight liner of steel hardness composite material that is resistant to corrosion, flames and heat.
The FuranFlex® tube is lined in the chimney yet in its soft state, whereas being inflated by steam, it takes the shape of the chimney and by the effect of the heat it gets irreversibly hardened to form a heat and corrosion resistant composite liner of steel hardness.

Why composite material?
FuranFlex® is made of thermosetting resin material with fibre glass reinforcement (composite), the physical (steel hardness) and chemical (acid-proof, alkali-proof) features of which make it perfectly suitable for lining chimneys. Its special resin composition guarantees its high heat-resistant capacity.
FuranFlex® has 25 years guarantee.
