Flexible flue liners are solid but lightweight tubes constructed from single sheets of steel, which are bent at 180° and folded at the seam for a quattro-lock seal. They are for use within existing chimney stacks to ensure that the smoke and gases produced from your appliance are safely released into the atmosphere, instead of into your property.
We offer flexible flue liner product ranges that have been specifically designed for use with either solid fuel or gas appliances, and are for internal use within a masonry chimney stack ONLY. These products are NOT for external installations - for external installations please see our twin wall range.
Our Quattro-Plus liners and installation components are constructed with you in mind; using high-quality materials we have created a comprehensive range of great value products that focus on ease-of-installation, longevity, affordability and suitability.
Installation It is highly recommended that solid fuel appliances are installed by HETAS registered installers and MUST adhere to the Building Regulations. All gas appliances MUST be installed by Gas Safe registered persons (it's is a legal requirement).
