Standing seam is a ventilated cladding system that can be used in both renovations and new build. As the name Standing seam explains, the system has upstanding seams that can be closed in a single or double fashion (for greater flatness single lock seams are recommended). It has a traditional look that’s much appreciated by architects (link to tab architect) and building owners (link to tab building owner). The trays can be installed horizontally or vertically. This façade system offers the possibility to clad all types of walls: flat, curved or complex. Another great advantage of this zinc façade system is that it can be used on both walls and roofs, thus allowing roof and wall to blend as one. You also have the possibility to chose different widths and lengths of trays, another way to be creative with this system is to use several surface appearances. Consult our project pictures and view some examples.
|Height of the seam||Centre to centre distance 500 mm coil width|
|H = 25 mm||430 mm|
|Length||to 4 m|
|Long trays available in different widths|
|Can be used in roof and façade applications|
|Is available in many surface finishes|
- Both renovations and new buildings.
- All shapes: flat, curved, concave, convex, conical, domes.
- The VMZINC is installed on metal or wooden support
Stages to install Single Lock Standing Seam:
|A continuous 38 mm ventilated air gap is to be left behind the boarding on the entire facade.|
|Continuous ventilation openings must be made at the top and bottom.|
The insulation panels must be sufficiently rigid and well anchored to their structure to prevent them from moving and blocking the ventilation space (refer to the insulation manufacturer's specifications).
- Clean and dry 100 to 150 mm wide by 18 or 24 mm thick softwood boards, depending on the centre-to-centre distance between bearing structure elements.
- Any wood treatment products (fungicides, insecticides) must be dry and completely neutral to VMZINC.
- 75° to 90° facades: install boards vertically leaving 3 to 5 mm between them.
- 90° facades: install boards vertically at 400 mm centre-to-centre. However, for the areas of the facade near by traffic, continuous boarding should be installed to a height of 2 m.
- Maximum difference in height of 1 mm between roof boards. The deflection measured under a rigid 600 mm long straight edge cannot exceed 2 mm in all directions.
- The nails fixing the boards are countersunk in order to avoid any contact with the VMZINC.
- Plywood can be used but ZINC PLUS must be applied in this situation
- The plastic film ( link to 9.8 remove the film) must be removed within 2 months of installation. The film should be left on if other trades are working in proximity of the zinc. The film must not be partially removed.
