Thermaflue - TH5-6 - 1 Metre Length

ThermaFlue is manufactured by Thermaflue Systems Limited in Doncaster, a leading mnaufacturer of insulating materials and products to industry.

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 with 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 hook and loop fasteners facilitate a taut fit around the flexible flue liner.

The inner wall is a high quality needled glass fibre that provides excellent mechanical resistance and stability. The outer wall is a moisture repellent silicone coated material.

Thermaflue is guaranteed for 10 years.

Thermaflue is manufactured in one metre sections and available in two widths. TH5-6 is suitable for 125mm and 150mm diameter liners and TH7-8 for 175mm and 200mm diameter.


Application
It is recommended that where chimneys are positioned on external walls, or where the chimney void is particularly large, that the flexible flue liner is insulated. This is to prevent the flue gasses from condensing which is highly corrosive and will result in the liner prematurely failing. Insulating a flexible flue liner helps maintain flue gas temperature and improve chimney and appliance performance.

Approval
ThermaFlue has been tested to EN1856-2 and can be used under normal operating conditions up to 600 degrees C. It is capable of withstanding higher temperatures but must be replaced, like the liner itself, after a chimney fire.
