therma flueThermaflue Gains HETAS Approval

Thermaflue is one of the latest products to gain HETAS approval. A high quality insulating sleeve that is owned and distributed by the Flue & Ducting team is available now with same and next day delivery available.

In early April 2017 David Gooding of Thermaflue retired and after working with David for the last 2 years the owners of Flue & Ducting Ltd saw Thermaflue as the perfect fit with their existing business and decided to acquire the business bringing the manufacture, phone lines, and website in house. Thermaflue’s head office is now based in Stockport alongside Flue & Ducting Ltd.

The two companies are completely separate Limited companies but Thermaflue now benefits from Flue & Ducting’s distribution network and sales force.

“We’ve recently had Thermaflue HETAS approved and the product is fast becoming a strong brand and popular item with the fitters. The advantages and benefits of Thermaflue are endless and to have this product in our offering is really pleasing” says Ryan Hancock, Thermaflue Director.

ThermaFlue is a high quality insulating sleeve for flexible flue liners. Each sleeve is hand manufactured and inspected to exacting standards. The sleeve is stitched steel-aramid sewing thread, ideal for high stress applications requiring extreme strength and heat protection. Each length has an overlap collar with a D-G link system that ensures consistent thermal insulation. Adjustable fire retardant Velcro hook and loop fasteners facilitate a taut fit around the flexible flue liner.

Thermaflue has been tested to BS EN1856-2:2009 with a designation number of T600 N1/P1/P2 D or W Vm(L*****) G. In the case of a chimney fire, like the liner, it must be replaced but it is capable of withstanding higher temperatures than a chimney liner and adds a real safety aspect to any installation to give the customer peace of mind.
By insulating the flue liner it also decreases the risk of condensation and enhances flue liner’s performance.


Thermaflue can be purchased through one of our stockists Flue & Ducting Ltd or IMS-insulation, Thermaflue is available for same and next day delivery UK wide.
