VMZ single lock standing seam

VMZ Standing seam warm roof

(non-vented)on plywood bonded to phenolic foam)

 

This system provides a continuour 18mm WBP exterior grade plywood substrate allowing greater flexibility installing the VMZINC PLUS finish, thus eliminating the need to penetrate the insulation layer with additional fixings thereby minimising thermal bridging. With this warm roof system VMZINC PLUS Standing Seam can be installed on Metdeck composite panels without ventilating the underside of the VMZINC PLUS. The substrate of the Metdeck composite panels (on the warm side of the roof panel) must be covered with a continuous aluminium foilbacked bituminous self-sealing vapour barrier.

 


 

Surface finishes as follows

- QUARTZ-ZINC PLUS or ANTHRA-ZINC PLUS
- AZENGAR PLUS
- PIGMENTO PLUS in blue, brown, green or red


 
 
Simplicité de pose Easy installation using traditional clips
Simplicité de pose Reduces thermal bridging
Technicité Excellent pull out resistance

 

  • The system can be used for roofs with a pitch from 3º to 60º and for buildings with humidity classes of between 1 or 4 (dwellings with high occupancy, sports halls etc). As with all warm (non-ventilated) roofs VMZINC PLUS must be used. This system provides a continuous 18mm WBP exterior grade plywood substrate allowing greater flexibility installing the VMZINC PLUS finish, thus eliminating the need to penetrate the insulation layer with additional fixings thereby minimising thermal bridging.

The substrate of the Metdeck composite panels (on the warm side of the roof panel) must be covered with a continuous aluminium foil-backed bituminous self-sealing vapour barrier to BS EN 13970:2004.

Condensation risk must be assessed for each individual project or individual project component in accordance with BS 5250:2002. Specification may need to be adapted to the internal humidity load of the building. The VMZINC Breather Membrane should be installed between the VMZINC PLUS and the Metdeck composite panels, then dressed into the gutter.

Metdeck composite panels, incorporating 18mm WBP plywood factory-bonded to a resol insulation core, are mechanically fixed to the substrate (vapour barrier on concrete, metal or timber deck). The number of fixings required will vary with specific building details and geographical location and must be assessed on an individual basis.
