Schiedel 6″ (150mm) Internal Diameter ICID Plus 135 Degree Wall Sleeve – Combustible Walls Up To 330mm Thick
The ICID Plus 150mm 135 degree wall sleeve is made from galvanised steel and is designed for safely passing a flue through a combustible wall up to 330mm thick.
This wall sleeve is part of the ICID Plus twin wall flue system, featuring a laser welded 316L stainless steel inner liner and a stainless steel casing for advanced corrosion resistance. It is insulated with 25mm of high density rockwool to maintain flue gas temperature, maximise efficiency, and reduce condensation.
Components are connected using a twist lock bayonet jointing system and secured with a locking band. A rubber joint seal allows the sleeve to be used safely with condensing and biomass appliances.
The ICID Plus twin wall insulated chimney system is suitable for open and closed stoves operating at temperatures up to 450°C. The load bearing outer casing allows the inner liner to expand independently, accommodating thermal expansion at every joint and ensuring long term durability.
