6 Inch Black Powder-Coated Twin Wall Flue Systems

Our 6 inch black powder-coated twin wall flue systems are designed for installing a stove in properties without an existing chimney. The double-walled construction efficiently channels exhaust gases while keeping the exterior cooler, making them suitable for straight or angled flue runs and multi-storey installations.

Why Do You Need a 6 Inch Black Twin Wall Flue?

  • Safe operation – double insulation reduces surface temperatures for safer handling
  • Regulation compliant – meets UK building regulations for stoves installed without a chimney
  • Flexible installation – works with straight or angled flue runs, including multi-storey setups
  • Durable design – black powder-coated stainless steel for long-lasting performance

Components and Accessories

Alongside the 6 inch black flue pipes, we stock all the components required for a complete installation:

  • Adaptors, bends, and T-pieces
  • Locking bands, brackets, and finishing plates
  • Top caps and rain cowls for protection and draft control

Before You Choose

6 inch twin wall flues are mainly needed for properties without a chimney or where the stove sits outside a current flue. Always check your stove type, property layout, and local building regulations. Professional installation by a HETAS-qualified engineer is strongly recommended for safety and compliance.
