lt;p>VMZINC Standing Seam is a ventilated cladding system that can be used for both renovation and new build. As the name standing seam implies, the system consists of seams that can be crimped in a single or double lock (for greater flatness single lock seams sometimes referred to as angle seams are recommended).</p> <p>The system has a traditional look with the seams being 25mm high. The trays can be installed horizontally, vertically and at an angle.</p> <p>This facade system offers the possibility to clad all types of walls: flat, curved or complex forms. Another great advantage of this zinc facade system is that it can be used on both walls and roofs, thus allowing roof and wall to blend as one (standing seam roofs require double lock seams).</p> <h2>Structure</h2> <p>The system is very lightweight as the panels weigh no more than 7 kg/m2 and can be fixed back to both soft wood open gap boarding and plywood. Both substrates require the use of 18mm thick wood and a vented airspace should be left behind the timber of at least 38mm. The plywood must be weather and boil proof. WBP plywood is more precisely described as EN314-2 (bond class 2) and EN636-2 (timber performance).</p> <p>When soft wood open gap boarding is used it is possible to omit every other board, however a fully boarded substrate should be used in accessible areas. The substrate must be flush to within 2mm and all screws and nails must be countersunk.</p> <p>VMZINC PLUS must be used on plywood substrates, however for vertical surfaces VMZINC and VMZINC Membrane can be used on vented plywood. For projects where combustible materials such as plywood cannot be used galvanised steel decks can be used as a substrate.</p> <p>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.
