Application

Wall cladding on flat and curved surfaces.
Roofing - minimum pitch, consult elZinc.

Description

The Rhomboid Tile is used to form the weathering layer in a fully supported zinc facade or roof. The zinc tile can be cut, folded and edged just as in traditional zinc work, providing weather-tight joints at the zinc cladding's edges.

The tiles are made of elZinc titanium zinc, 0.65 or 0.7 mm thick rolled to EN 988 and ASTM B69-13. Centre to centre joint width is 235 mm. Cladding weight is 7.8 kg/m² with 0.7 mm thick tiles. The tiles are interlocked with each other and fixed directly to the wooden substrate (softwood boarding or plywood or OSB sheathing) using one stainless A2 grade fastener. 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.

Facade application:

The cladding is normally rear-vented behind the supporting sheathing/boarding with a ventilating space of at least 38 mm. Over sheathing, a simple breather membrane is normally installed between the zinc and the substrate to act as a separating layer. Over boarding, no membrane is required.

Roofing application:

The roof is either ventilated with a ventilating space of between 50 and 100 mm (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.

Features and benefits:

Traditional cladding system using interlocking panels.
Principally used in facade cladding, on flat or curved areas.
Weather-tight from 25º of pitch and above if used in roofing (consult with manufacturer for your project).
Attractive design layouts complement different architectural styles.

Specification data - Zinc sheet fully supported wall-covering systems

System performance elZinc Rhomboid 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 Insert requirement. A zinc façade does not place any special requirement on the insulation.	-
Air and vapour control layer Insert requirement.	Not required. Breather membrane. Insert requirement.
Carrier Insert requirements.	Soft wood battens. 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. Use metal rails for metal decks, insulated metal panels.
Substrate Insert details.	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.
Sheet underlay	-
Material	Not required. Vented open gap boarding substrate. Structural underlay. Open fibrous mat, 8 mm (over breather membrane, sd value of 0,04 m). Edges of breather lapped and taped. Unvented substrates without elZinc Protect+ backcoat - structural underlay (breather membrane + mat). Breather membrane. Max sd value of 0.04 m. Edges lapped and taped. Vented plywood sheathing / metal deck. Unvented substrates with elZinc Protect+ backcoated zinc.
Zinc sheet Rolled according to EN988 and ASTM B69-13.	0.7 mm-thick elZinc® titanium zinc. Consider using Protect+ back coating for unvented façades. Contact manufacturer for further guidance 0.8 mm-thick elZinc® titanium zinc. Preferred for façades to keep oil canning to a minimum. Consider using Protect+ back coating for unvented façades. Contact manufacturer for further guidance

Execution Joints 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 direct through the hole at the top corner of the shingle. The top fixing gives 14 fasteners/m². Depending on the pull-out value of the fastener, this should be enough for buildings in sheltered locations. Tile direct fixed plus one stainless steel clip per edge. Clip spacing along the edges of the facade and at the corners may require using additional clips. For buildings located in exposed areas or over 8 m in height, or in regions exposed to tropical storms, specify one clip per edge.
Colour/ Finish If 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®. elZinc Rainbow® Black. elZinc Rainbow® Blue. elZinc Rainbow® Brown. elZinc Rainbow® Gold. elZinc Rainbow® Green. elZinc Rainbow® Red. elZinc Slate®.
