Ultraflex Flue Liner Components

Originally designed as just a liner, the huge success of this product meant we were asked to develop a wider range. So, we listened to our customers and expanded our product range.

The ULTRAFLEX brand now includes:

• Flexible Chimney Flue Liner
• Flue / Chimney Adaptors
• Register Plates
• Supports
• Terminals
• Cowls

Think Quality – Think ULTRAFLEX

Whilst some will cut corners, reduce the thickness of their steel (WE WILL NEVER DO THIS) at FSM Group, we work closely with our customers to give them the products they need, but most importantly deserve! ULTRAFLEX was no different. We do not compromise on quality, and that is why we are confident that it will not let you down.

Our ULTRAFLEX flue liners are the ideal solution for lining an existing chimney stack. With superior protection against carbon monoxide leakage & creosote build-up, they also improve the draw of the chimney and efficiency of your appliance or fireplace. ULTRAFLEX Flue Liners are available in 4 – 10 inch diameters and are suitable for use with multi fuel stoves, wood burning stoves & open fireplaces. Available to purchase by the metre or as complete flue liner kits.
