Twin wall is a flue system composed of two cylindrical steel pipes inside each other with a layer of insulation between the two; the internal layer has a diameter 2" smaller than the outer layer (each layer is 0.4mm thick). Twin wall is the only type of flue system that can be used for the external installation of wood burning, multi-fuel, gas and oil appliances. So, If your property does not have an accessible (masonry) chimney stack, or if it only has part of one, then this is the system for you!

Painstakingly constructed from high-quality 304 and 316-grade steel, with compressed rock wool for insulation, the KC twin wall system is suitable for most solid fuel, gas and oil appliance installations and is for both internal and external use.

An installer-friendly product, with an open-ended construction to eradicate hotspots in the pipe; the KC range can withstand temperatures of up to 600°C and has a 60mm clearance to combustibles. Components are secured together using locking bands (included) and are available in chrome stainless steel or can be powder-coated to a matt-black finish.

We provide full installations in our KC range, stocking a comprehensive selection of products, including pipes, bends, wall sleeves, flashings, cowls, adjustable wall supports and much more - all available in (internal) diameters ranging from 4-8 inches.
