VMZ single lock standing seam

VMZ Double lock standing seam

What is VMZ Double lock standing seam?

The VMZ Double lock standing seam system used on roofing applications enables long strips of VMZINC to be assembled by forming single or double folds on the up-stands.


A traditional technique applied to roofs. This technique can be machine or hand produced. It reflects the individual architect’s concerns for lines and shadows, producing designs that have a historical perspective.


The low height of the seams 1” (25 mm) and 1 1/2” (38 mm) contributes to the lightness and regularity of the roofing in its architectural function, particularly when used on more complex shapes, giving them a distinctive “high-tech” appearance.


Due to the use of profiling and seaming machines for closing the longitudinal standing seam joints, the installation time is greatly reduced, making this a cost-effective solution, particularly for very large roof surfaces.


This technique utilizes less metal in comparison with the batten (roll cap) method.

  • This system is particularly suitable for very large roof surfaces and for structures located in regions of harsh climate, which are often subject to snowfall (mountainous or continental climate), strong winds, and heavy rain. VMZINC has a theoretical thermal expansion coefficient of 1/64”/ft for 212°F temperature change (2.2 mm/m for 100°C change). In addition, it offers very good wind resistance in extremely windy areas. It is possible to modify the number of fixing clips required according to the prevailing climatic conditions.
  • Coverage: plus or minus 1/16” (1.6 mm)
  • Flatness at maximum deflection: 5/64” on 36” (2 mm on 914 mm)
  • Curvature: 1/32” (0.8mm)
  • Roof pitch 1:12
1

Examine substrates, areas, and conditions for compliance with requirements for installation tolerances, metal wall panel supports, and other conditions affecting performance of work.

2

Verify that substrate is plumb, sound, dry, smooth, clean, sloped for drainage, and completely anchored, and that provision has been made for wall drains, flashings, and penetrations through metal wall panels.

Examine primary and secondary wall framing to verify wherther or not purlins, angles, channels, and other structural panel support members and anchorages have been installed correctly.
4 Prepare written report, listing conditions detrimental to performance of work of this section. Submit copy of report to architect.
5

Examine roughing-in for components and systems penetrating metal wall panels to verify actual locations of penetrations relative to seam locations of metal wall panels before wall panel installation.

6 Install metal wall panels in orientation, sizes, and locations as indicated on the drawings.
7 Install metal wall panels plumb, level, square, true to line, and within installation tolerances.
8 Install metal wall panels perpendicular to girts and subgirts, unless otherwise indicated.
Anchor metal wall panels and other components of the work securely in place, with provisions for thermal and structural movement. Do not use a torch to field-cut metal wall panels.
Fasten metal wall panels in accordance with manufacturer’s instructions. Panels to be installed on vertical lines 28cm on center. Flash and seal metal wall panels with weather closure edges and at the perimeters of openings.
Install flashing and trim as metal wall panel work proceeds. Fasten flashings and trim around openings and similar elements.
Maintain metal wall panels in clean condition during installation. Remove protective film within 90 days of installation.
