The Embellisher is made from 316 grade stainless steel with an internal diameter of 150mm and an external diameter of 200mm. It is always used in conjunction with a single to twin adaptor and has a purely aesthetic purpose; it is designed to slot onto the adaptor and sit halfway down so it hides the insulation of the pipe that the adaptor is connecting to. Made from 316 grade stainless steel. 30mm high grade insulation promotes efficient performance and protects against the build up of condensates within the flue system. All twin wall flue components are CE approved. There is only a 50mm clearance from combustible materials needed when using our twin wall flue. Every twin wall flue component is supplied as standard in stainless steel however we do offer a powder coating service to RAL colours for an additional cost, which allows the components to be supplied to you in a range of different colours to better suit your property. Please contact us for more information regarding this service.
