The Schiedel Ventilated Round Firestop 2pc for twin wall flue is a two-piece ventilated firestop component available for 130mm (5″) and 150mm (6″) internal diameter chimney systems. Its round, two-part format allows it to form part of the firestop arrangement around the corresponding Schiedel twin wall flue.
This component is listed for use with Schiedel twin wall chimney systems, including the associated ICS and ICID ranges. The two available sizes allow the firestop to be matched to either a 130mm or 150mm internal diameter system.
The wider Schiedel ICS system is a twin wall insulated chimney system used with open and closed stoves, open fires, and residential or small commercial multi-fuel appliances. It is rated for continuous operating temperatures up to 450°C and short firing temperatures up to 550°C.
The associated ICS chimney system uses a push-fit jointing arrangement secured by locking bands. Its construction incorporates laser-welded 316L stainless steel inner liners, a 304 stainless steel outer case and a 25mm Superwool insulation blanket. These specifications relate to the wider chimney system rather than the firestop component itself.
The firestop is supplied as a two-piece component, which is an important distinction when selecting accessories for the flue route. The appropriate version should be chosen according to the internal diameter of the corresponding twin wall system.
