A fully supported zinc cladding system composed of overlapping zinc tiles.
elZinc Square tiles are direct fixed cladding elements for roofing and cladding. The tiles overlap to form a continuous weathering layer, providing a bold structured pattern across the facade with joints angled at 45º. They are supplied with an optional polystryrene backing for roofing applications which deadens rain drumming and increases the tile's rigidity. For projects that require a non combustible cladding, the tile should be ordered without this backing.
Features and benefits:
Color | Grey Light grey, medium grey or dark grey. Red Blue Brown Gold |
Finish | Natural Pre-weathered |
MaterialTiles should be specced without the XPS backing for buildings with a reaction to fire requirement for the cladding | Expanded polystyrene (EPS) Titanium Zinc |
Shape | Square |
Length | 555 mm |
Width | 512 mm |

System performanceelZinc Square tiles shall provide a weathertight wall cladding, able to freely expand and contract in response to temperature changes, and fitted to resist all loading including wind loads. The appearance of the cladding shall be one composed of flat panels, without oil canning, of straight joints and neat folds of flashing elements, correctly set out according to the architect’s drawings and design intent. | - |

Substrate | Sheathing/ boarding.Sheathing/ boarding 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. Ventilated plywood substrate, 18 mm.Service class 2 according to EN636, and 'good one side'. Installed in a staggered layout, parallel to eaves, with a 3-5 mm gap between boards, all edges supported and fastener heads driven below surface. Ventilated galvanized steel metal deck, 0.7 mm.0.7 mm minimum. To give a minimum clip pull-out value of 560 N, installed 'façade side outwards' to give maximum support to the zinc trays, parallel to eaves, all ends supported. Open gap softwood boarding according to EN 12775-2, 18 mm.Maximum moisture content 18% and compatible with zinc and treated with zinc-compatible wood preservatives, rough sawn, 18 mm thick minimum, 80 to 125 mm wide, fixed parallel to eaves with fastener heads driven just below surface. Foamglas insulating boards.Installed according to manufacturer's instructions, providing a vapour-tight substrate. |

ExecutionJoints shall set out according to architect’s drawings, or in their absence, according to the design intent of the project. The details of the zinc work should be carried out according recognized good practice and manufacturer’s recommendations. Respect minimum recommended interior radii while bending. Holes should be notched where required to prevent tears forming in the zinc. Marking out: Use a pencil, pen, crayon or chalk. After completion, no marking should be visible. Wherever possible use a mechanical folder to bend material to give straight and uniform folds. Free edges: If visible fold over to form a 15 mm hem. Ensure the temperature of the metal does not fall below 7, or 10°C, depending on the operation, when folding, profiling or forming the metal. Follow elZinc recommendations regarding warming up zinc metal prior to forming. | - |
Fixing | Tile direct fixed. Tiles are direct fixed through a hole at the top corner and of the tile, and through holes on the left and right corners. The bottom chamfered corner slots into pockets on the left and right side of the tiles on the row below. This gives 26 fasteners/m². |
Colour/ FinishIf a backside coating is required, type 'Protect+' directly after the finish, eg. elZinc Graphite® Protect+. If an ‘Advance’ finish is required, type ‘Advance’ directly after the finish, eg. elZinc Slate Advance. | elZinc Crystal®. elZinc Graphite®. elZinc Lava®. elZinc Natural. elZinc Oliva®. |
