The 316 grade stainless steel Wall Band is essential for use where twin wall flue pipe in the system is running unsupported for more than 1.5 metres. You need one adjustable band every 1.5 metres of the system. The wall band connects to the internal/external wall and allows for an adjustment between 354mm-554mm away from the wall. 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.
