For simplicity the flue wrap jackets are supplied in one universal size which is one metre long and fits all flue pipes from 5” (125mm) to 8” (200mm) diameters. The fixing straps are simply wrapped around until two of the holes line up and a simple metal tie is pushed through the two holes to secure the strap. The chimney jackets should be fixed so that the higher one always overlaps the next lower one a little so that any debris which falls down the chimney will not lodge in the joints.
