A fully supported zinc cladding system composed of overlapping zinc tiles.
Application
- Wall cladding on flat surfaces.
- Roofing - minimum pitch - consult elZinc.
Description
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:
- Traditional cladding system using overlapping panels.
- Principally used in facade cladding.
- Nominally weather-tight from 25º of pitch and above if used in roofing. Check with manufacturer for your project.
- Easy and quick to install.

Specification data - Zinc sheet fully supported wall-covering systems
System performance | Manufacturer guidanceelZinc 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. |
Insulation | Manufacturer guidanceInsert requirement. A zinc façade does not place any special requirement on the insulation. |
Air and vapour control layer | Not required.Breather membrane.Guidance for specification option: Insert requirement. Manufacturer guidanceInsert requirement. |
Carrier | Soft wood battens.Guidance for specification option: With suitable wood preservative treatment, height 38 mm minimum or according to ventilating cavity depth. Use soft wood battens for open gap boarding, plywood or OSB sheathing. Metal rails.Guidance for specification option: Use metal rails for metal decks, insulated metal panels. Manufacturer guidanceInsert requirements. |
Substrate | Sheathing/ boarding.Guidance for specification option: 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.Guidance for specification option: 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.Guidance for specification option: 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.Guidance for specification option: 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.Guidance for specification option: Installed according to manufacturer's instructions, providing a vapour-tight substrate. |

Execution | Manufacturer guidanceJoints 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. Guidance for specification option: 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/ Finish | elZinc Crystal®. elZinc Graphite®. elZinc Lava®. elZinc Natural. elZinc Oliva®. Manufacturer guidanceIf 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. |
