5 Inch Twin Wall Flue Systems
Our 5 inch twin wall flue systems allow you to install a stove safely in properties without an existing chimney. The double-walled design ensures exhaust gases are expelled efficiently while keeping the outer surface cooler, making them suitable for both single and multi-storey installations.

- Compliance – designed to meet UK building regulations for stoves without a chimney
- Flexible installation – works for straight or angled flue runs, including multi-storey setups

Before You Choose
5 inch twin wall flues are primarily required for homes without a chimney or where your stove will be outside an existing flue. Check your stove type, property layout, and local building regulations. Professional installation by a HETAS-qualified engineer is strongly recommended.
