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.

Why Do You Need a 5 Inch Twin Wall Flue?

  • Safe operation – double insulation protects against high surface temperatures
  • 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
  • Durable materials – crafted from high-quality stainless steel for long-lasting performance

Components and Accessories

Alongside the 5 inch flue pipes, we stock all the parts you need to complete your 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

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.
