Shop our range of Thermotec T600 insulated twin wall flue, with the components you need to build a complete stove and chimney system.

Available in standard 125mm (5") and 150mm (6") sizes, the range includes straight and adjustable lengths, bends, tees, adaptors, brackets, supports and terminals, with stainless steel and matt black finishes available.

Thermotec T600 is a fully insulated system for installations where a suitable masonry chimney isn't available, or where the flue needs to continue safely through the building or externally. Its twist-lock components make it straightforward to build the route your installation needs.

The T600 system is tested to EN 1856 and is backed by a 15-year Thermotec guarantee, subject to the manufacturer's registration, installation and maintenance requirements.

Not sure how your system needs to come together? Take a look at the Thermotec technical documents below, or get in touch with our team and we'll help you work through the parts you need.
