5 Inch (125mm) Black Twin Wall Flue

5 Inch Black Powder-Coated Twin Wall Flue Systems

Our 5 inch black powder-coated twin wall flue systems are perfect for installing a stove in homes without an existing chimney. The double-walled design efficiently channels exhaust gases while keeping the exterior cooler, making them suitable for both single-storey and multi-storey installations.

Why Do You Need a 5 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 a long-lasting finish

Components and Accessories

Alongside the 5 inch black flue pipes, we supply 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 added protection and draft control

Before You Choose

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