elZinc® angle seam is a traditional fully supported architectural cladding system composed of site-seamed zinc trays. The seamed joint is 25mm high and has a 12mm front face.
The zinc angle seam cladding can be used to clad façades (tray dirección can be horizontal, vertical, or at angle) and roofs pitched above 25º (35º in regions with heavy snowfall). The zinc angle seam trays can be tapered, pre-curved to concave or convex panels, so almost any architectural geometry can be weathered using this system.
Angle seam façades exhibit fairly pronounced visual directionality, and various designs are available for creating different effects that can be used to reinforce the architectural design intent.
Slight oil canning (quilting) is sometimes apparent, adding extra character to the zinc façade.
Zinc angle seam traditional fully supported cladding composed of standing seam trays seamed together on site. The trays are made of 0,7 or 0,8mm thick elZinc® titanium zinc rolled according to EN988 and ASTM B69-13
Normal tray widths: 430, 530, and 600mm. Cladding weight (zinc only) is between 6 and 7 kgs/m2.
Trays are fixed back to sheathing / boarding using stainless steel clips secured at pre-determined centres (according to exposure) by stainless steel (A2 grade) fasteners. Sheathing / boarding to be laid flush, true and plumb, and its fasteners driven just below the surface. For buildings that require a non-combustible substrate for the zinc, trapezoidal metal sheet panels are used as a substitute for the wooden sheathing / boarding.
Façade application: The cladding is normally rear-vented behind the supporting sheathing / boarding with a ventilating space of at least 20mm (some countries require more). A simple breather membrane is normally installed between the zinc and the substrate to act as a separating layer.
Roofing application: The roof is either ventilated with a ventilating space of between 50 and 100mm (depending on rafter length) under the substrate, or installed in an unventilated (warm) roof design which includes suitable methods for condensation control. A structural underlay (and draining membrane) is often required under the zinc to ensure air circulation to its underside.
