Flexible Chimney Liners

In grade 316L or 904L, STARFLEX is a double skin, smooth bore stainless steel flexible multi-fuel flue liner. This range is perfect for the renovation of existing masonry chimneys with offsets, for multi-fuel and wood burning stoves.

With old brick-built chimneys over the years the condition of the brick work will become warn and damaged through use and weathering. When the original lining of the old flue becomes unsound, the particles of the combustion and toxic fumes can leak from the flue into the neighbouring flues and other parts of the home.

A chimney sweep or smoke test can be carried out to investigate the condition of a flue, we always ensure that a chimney has been inspected and certified before any appliance is installed by us, and if you would like us to carry out the full service of checking your chimney and fitting your fireplace we are more than happy to do so. The only thing you have to worry about is what fireplace to choose!

FuranFlex® Chimney Liner

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.

The advantages of the FuranFlex® Chimney Liner are:

- No demolishing required and living spaces remain clean during the chimney lining works
- Lining the chimney only takes a few hours and it can be applied at all types of chimneys up to 100 m height and 120 cm diameter
- The inner surface is smooth and the insulating capacity helps fires operate economically
- It does not corrode and a 25 year guarantee is provided for corrosion damages
