VMZINC, the choices
Only "PLUS" type VMZINC with a specially protected underside:
Natural VMZINC PLUS,QUARTZ-ZINC® PLUS,ANTHRA-ZINC® PLUS,
PIGMENTO® VMZINC PLUS: 0.7 mm thick.
Characteristics of this technique

With this warm roof system VMZINC PLUS standing seam can be
installed on composite panels without ventilating the underside
of the VMZINC PLUS.For all applications:

1.The substrate of the composite panels (on the warm side of the roof panel)
must be covered with a vapour control layer material with vapour resistance
always greater than the sum of the resistance of the elements
fixed above the vapour control layer.
It must be adapted to the internal humidity load of the building.
2.The joints between the sandwich panels must be totally air tight
and have good vapour retarder properties.
3.Breather membrane (type DALTEX Roofshield or equivalent) should be installed
between the VMZINC PLUS and the composite panels.

Structure

A choice of:
Upper layer of the composite panel: solide wood panels or other panels,
all certified for roofing applications (min. thickness: 12 mm).
Particular attention to be put on certification of the upper facing of
these panels for roofing usage.Upper layer able to resist pull out forces of
50daN/standing seam fixing clip (dynamic testing method).
Aluminium internal and external facing
(min. thickness: 0.7 mm for external facing).
Particular attention to be put on certification of these
panels for roofing usage.Upper layer able to resist pull out forces of
50daN/standing seam fixing clip (dynamic testing method).Timber deck.

No delamination of the panel and pull out resistance decrease under wet conditions.
N.B. The information relating to the installation of the composite panels
and membranes is simply an indication.
The choice and installation of these products will be according to the
recommendations of the panels and membrane manufacturers
