Application

  • Both renovations and new buildings.
  • All shapes: Flat, curved, concave, convex, conical, domes.

Description

A ventilated cladding system that can be used for both renovation and new build. As the name implies, the system consists of seams that can be crimped in a single or double lock (for greater flatness single lock seams, sometimes referred to as angle seams, are recommended). The system has a traditional look with the seams being 25 mm high. The trays can be installed horizontally, vertically and at an angle.

The facade system offers the possibility to clad all types of walls: flat, curved or complex forms. Another advantage of this zinc facade system is that it can be used on both walls and roofs, thus allowing roof and wall to blend as one (standing seam roofs require double lock seams, and are specified separately).

The cladding panels can be various sizes - it is recommended that they be no more than 4000 mm in length and 430 mm in width; consult manufacturer for details. All aspects of VMZINC can be used, with 0.8 mm being the recommended thickness for facades.

Features and benefits:

  • Covered by Code of Practice 143-5: 1964.
  • Concealed fasteners.
  • Roof to wall continuity (roofing specified separately).
  • Versatile.
  • Horizontal, vertical and diagonal (angled) installation possible.
  • 25 mm high seam.

Typical system build-up:

  • VMZ standing seam panels in VMZINC® PLUS.
  • Fixing clip.
  • 18 mm plywood or steel deck.
  • Battens creating a vented 38 mm airspace.
  • Insulation protected by VMZINC® Membrane.

VMZINC® PLUS:

A product which allows zinc to be installed on ventilated plywood as well as specific warm (non-ventilated) substrates. The product consists of VMZINC (in all finishes) having a 60 µm coating applied to the underside thus allowing a more varied amount of substrates to be used and eliminating the risk of the formation of white rust on the underside of the zinc standing seam panels. VMZINC PLUS resists to an abrasion of 140 L when tested in accordance with ASTM D 968.

Life Cycle Analysis (LCA):

VMZINC undertakes Life Cycle Analysis (LCA) tests on its products and publishes Environmental Product Declarations (EPDs), such as BRE Environmental Profiles, available from the manufacturer's website www.vmzinc.co.uk and www.greenbooklive.com. These provide users with comprehensive, reliable and transparent information on relevant environmental characteristics. The information is also used by VMZINC as the basis for its eco-design approach.

Fixing standing seam joints

Standing seam fixed clips

Guidance for specification option:

For panels less than 2 m in length. When using single lock all clips can be fixed.

Standing seam sliding clips

Guidance for specification option:

For longer panels sliding clips must be used towards the bottom on vertical panels and to the left and right of the centre for horizontal panels.

Manufacturer guidance

 VMZINC clips are made from 1.4301 (304) grade stainless steel and each clip must resist a pull-out force of 50 daN.

Fasteners to substrate

It is recommended that screws be used to secure the clips with three being used per sliding clip. The use of nails offers significantly less resistance, but in the event of using nails, contractors are advised to use ring shank nails.

Colour

Natural VMZINC®, natural finish.

Guidance for specification option:

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.

Standard PIGMENTO® BLUE.

Guidance for specification option:

  • Pre-weathered finish.
  • Colouration of the zinc is achieved with a special pigment layer that enhances the qualities of the zinc without presenting a block colour.
  • Tested to EN 13523.
  • Provides an increased resilience. However in a severe non-rinsed marine environment (1 km from the sea), staining is still possible and therefore the material should not be used in this application.

Standard PIGMENTO® GREEN.

Guidance for specification option:

  • Pre-weathered finish.
  • Colouration of the zinc is achieved with a special pigment layer that enhances the qualities of the zinc without presenting a block colour.
  • Tested to EN 13523.
  • Provides an increased resilience. However in a severe non-rinsed marine environment (1 km from the sea), staining is still possible and therefore the material should not be used in this application.

Standard PIGMENTO® BROWN.

Guidance for specification option:

  • Pre-weathered finish.
  • Colouration of the zinc is achieved with a special pigment layer that enhances the qualities of the zinc without presenting a block colour.
  • Tested to EN 13523.

QUARTZ-ZINC®.

Guidance for specification option:

  • Pre-weathered finish.
  • 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®.

Guidance for specification option:

  • Pre-weathered finish.
  • With its visible grain it matches the colour of slate and blends well in combination with photovoltaic panels.
  • 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.
