lt;p>VMZINC Flat Lock panels, sometimes known as shingles, are installed on a continuous vented substrate on both renovation projects and new build alike. The system consists of panels with 180 degree hems approximately 25mm wide that interlock and are held on the substrate using cleats. The system allows a great deal of flexibility as flat lock panels can be made to many shapes and sizes. The panels can be square, diamond shaped and rectangular.</p> <h2>Structure</h2> <p>The system is very lightweight as the panels weigh no more than 8 kg/m2 and can be fixed back to both soft wood open gap boarding and plywood. Both substrates require the use of continuous 18mm thick wood and a vented airspace should be left behind the timber of at least 38mm. VMZINC PLUS must be used on plywood substrates. For vertical surfaces VMZINC can be used on vented plywood with VMZINC Membrane. </p> <p>For projects where combustible materials such as plywood cannot be used galvanised a 0.7mm galvanised steel deck can be used as a substrate.  By combining this with mineral board insulation, all materials in the wall build up are A1 or A2 according to EN 13501. The steel deck must be at least 0.7mm thick and have dimensions allowing clips to be attached at the required spacings. Corrugated steel deck can only be used on vertical surfaces. For all surfaces such as sills, parapets, etc the substrate must be continuous. The 38mm vented cavity can be fire stopped using continuous vertical cavity barriers and intumescent horizontal cavity barriers.</p> <h2>Drawings</h2> <p>Please find below files containing a selection of drawings.
