VMZINC® Zinc Sheet - For Facade, Roofing or Rainwater Systems

VMZINC® has been used as a material to clad facades for many decades. VMZINC sheet can be used to create facade, roofing and rainwater systems.

Initially traditional roofing systems such as standing seam panels were installed as ‘roofs on walls’. Flat lock panels have also been installed for many decades. Both of these systems require vented continuous substrates and are commonly installed by traditional hard metal roofing contractors.

Over the past two decades rainscreen facades have become very popular and VMZINC® offers a number of these rainscreen systems.

Surface finishes:

VMZINC® is a non-ferrous, self-protecting metal. Natural zinc forms its own protective layer, called a patina, when it is in contact over time with air (oxygen and carbon dioxide) and water. VMZINC® offers ten zinc surface colours in addition to the natural zinc which is sometimes referred to as mill finish zinc.

• Natural VMZINC® has a shiny metallic appearance when new and develops a patina over time. In facade applications, it may take ten years for the matt grey patina to form.
• QUARTZ-ZINC® offers an appearance and texture that does not change over time. When QUARTZ-ZINC® is scratched, it will self heal. The grey tones of QUARTZ-ZINC® blend well with existing construction materials. QUARTZ-ZINC® is produced through a phosphatation of mill finish Natural zinc. The darkness of the pre-weathered zinc is measured electronically using a Y figure where 0 is black and 100 is white. Acceptable tolerance of QUARTZ-ZINC®, Y = 22 to 25.
• ANTHRA-ZINC® with its visible grain matches the colour of slate and blends well in combination with photovoltaic panels. ANTHRA-ZINC® is produced through a phosphatation of mill finish Natural zinc. Acceptable tolerance of ANTHRA-ZINC®, Y = 5 to 7. Due to the dark colour of ANTHRA-ZINC® it should be carefully considered before using on non-rinsed surfaces such as protected facades and soffits. For rinsed surfaces in coastal environments ANTHRA-ZINC® STRAT should be considered.
• AZENGAR® is the surface finish from VMZINC® which is the first engraved zinc giving a product with a matt, heterogeneous and light aspect. AZENGAR® can be used in the same fashion as other VMZINC® products for both roofs and facades.
• Standard PIGMENTO® finishes offer an exclusive range of colours that enhances any building. This natural product enables the texture of the QUARTZ-ZINC® to still be seen whilst offering the designer the choice of colour to complement other elements of a facade or roof. The colouration of the zinc is achieved with a special pigment layer that enhances the qualities of the zinc without presenting a block colour. This product is tested to EN 13523. PIGMENTO®, available in seven standard colours, provides an increased resilience, however in a severe non-rinsed marine environment (1km from the sea), staining is still possible and therefore the material should not be used in this application. VMZINC® is not a painted product and therefore colour variations may occur. No colour matches are guaranteed therefore zinc should be installed from the same coil/ batch because of colour variations in the manufacturing process.
• PIGMENTO® range is also available in bespoke colours for a minimum order quantity of 3 tonnes.

Perforations and customization:

• Almost all VMZINC® rainscreen facade panels can be perforated. This can vary from standard perforations to custom perforations creating various patterns, even images and logos.
• Panels can also be curved and/ or customized e.g. custom stamping.
