VentiFlex® Lining


Hi tech relining solution

Flexible composite liner for ventilation ducts/exhaust ducts.
Ideal for all ducting restoration.

What is VentilFlex25?

VentilFlex25 is based on a glass fibre reinforced thermosetting resin, which is as strong as steel, when set, but has much better corrosion resistance than other materials. It is extremely thin (circa 3mm), has no joints and is installed by Kompozit’allUK’s trained and certified engineers, providing the guaranteed solution for all lining applications.

Due to its unique chemical formulation VentilFlex25 is suitable for lining and construction of air engineering ducts and VentilFlex25 RKV for heat resistant kitchen extraction applications. It is installed as one continuous lining, totally waterproof and airtight liner, making it ideal for kitchen extractors, providing a smooth easily cleaned duct and access is only required at the ends. Kitchen extractor ducts up to 1000mm diameter and over 50m in length have been installed swiftly to ensure the kitchens stay open.

All duct shapes can be obtained, rectangular, triangular, circular and many more.

  • High strength
