Simplicité de pose Plywood decking is readily available and widely used
Technicité Provides excellent pull-out resistance

 

  • Plywood boards must be at least 18mm thick and of exterior grade.
  • All the substrates must be flat, dry, and sufficiently resistant to stress (e.g. pull-out force of 50 daN per standing seam fixing clip). This resistance needs to be guaranteed through ageing and humidity.
  • Maximum difference in height of 1mm between support elements of the VMZ ZINC PLUS. The deflection measured under a rigid 600mm long straight edge cannot exceed 2mm in all directions.
  • The nails/screws are countersunk in order to avoid any contact with the VMZ ZINC PLUS.

In order to keep the integrity of the roof, it is recommended to install VMZINC breather membrane on the cold side of the insulation and a vapour control layer adapted to the internal humidity load of the building, on the warm side of the insulation. A bituminous vapour barrier is recommended.
