fabrics coated with waterproof silicone. It is fastened together by strips and buckles
and a patented D-G linking rings system.
Installing ThermaFlue gives an advantage to any duct that is renovated using a flexible

rooms on all four sides.

BSRIA according to BS EN1856-2:2009 and approved by HETAS
f) it has a rating of T600 N1/P1/P2 D/W Vm (L*****) G which means that it does not
decrease the designation of any liner available on the market

h) it has got a patented connecting system with D-G links
k) improves environment friendliness of a system; the warmer the liner, the better
