VMZ single lock standing seam

VMZ Single lock standing seam

What is Single lock standing seam system?
 

Single lock standing seam system is used for facade application. It has a taut and regular appearance. The procedure consists of welting the sheets to one another, along their entire length by single folding the panel's side upstands together.


Characteristics of this technique
 
  • VMZ Zinc plus Single lock standing seam (SLSS) is installed on a minimum 15 mm plywood.
  • An anti abrasive building paper (i.e Tyvek) must be laid between VMZ Zinc plus and plywood.
  • A 20 mm continuous ventilation gap must be left clear beneath the plywood.
  • Air inlets and outlets shall be provided at both top and bottom.


Surface aspects: QUARTZ-ZINC in VMZ Zinc plus / ANTHRA-ZINC in VMZ Zinc plus / PIGMENTO in VMZ Zinc plus

 

What is VMZ Zinc plus?


VMZ Zinc plus is VMZINC coated on the underside with a protective layer (Umicore patent).

  • Allows the use of an incompatible roof deck.
  • VMZ Zinc plus products can be bent, folded or profiled without any surface change (similar to VMZINC products) and thus allow the exact methods of laying.

Minimum pitch 60° - 90°
Maximum panel length 4 m
 
Economical Economical: The use of profiling and seaming machines for the closure of longitudinal seam joints significantly reduces installation time. This reduction makes for a more cost-effective solution, particularly when considering very large surface areas.
Discrete Discrete: The low height of the seams (25 mm) contributes to the agility and uniformity of the roof, whilst highlighting its architectural purpose. When dealing with more complex designs this system portrays a more technologically advanced appearance.
  • From 60 ° to 90 °.
  • Both renovations and new buildings.
  • Useable length : up to 4 m.
  • 2 types if installation: Vertically or Horizontally.

Stages to install VMZ Single Lock Standing Seam:

1 Lay the panel on the ventilated plywood sub structure.
2 Clips are fixed. Due to the theoretical thermal expansion two types of clips are used: fixed and sliding clips.
Vertical: A fixed area is created with 5 clips at the top of the panel and then sliding clips are distributed.
Horizontal: A fixed area is created with 5 clips in the middle of the panel and then sliding clips are distributed.
3 Single lock seam:
Crimp standing seams with manufacturer-approved tools so cleat, sheet metal roofing, and field-applied seam sealer are completely engaged.
