VMZ Overlapping panel is a wall-mounted cladding system made up of horizontal overlapping panels fixed to the substructure using brackets. The system is designed to be compatible with external insulation.
The panels fit easily into each other, making them quick and easy to install.

Easy to install : VMZ Overlapping panel is lightweight and easy to install: the panels fit easily into each other.
The panels can be cut easily on-site, without creating any dust.
|A low maintenance material : Zinc does not require any particular maintenance. It remains aesthetically harmonious throughout its lifespan.|
|Economic in the purchase and in the pose, VMZ Clin can be installed with a thermal insulation from the outside to increase performance.|
|A durable natural material : VMZ Overlapping panel is manufactured using rolled copper titanium zinc that complies with European standard EN 988. It is also rot-proof and non-flammable.|
|Sustainable solution that fits into its environment. Zinc is 100% recyclable. The nuances of VMZINC allow an optimized interaction with other materials.|
Flat, vertical supports in plastered brickwork or concrete, or on wooden or metal substructures, on new or renovated buildings.
Maximum building height is 40 m (maximum altitude 900 m).
The wall-mounted framework (not supplied) can be wooden or metal (galvanized steel, aluminium). The frameworks are fixed to the main structure with galvanized steel or aluminium adjustable brackets, using screws and wall plugs suited to the support.Reaction to fire
The zinc cladding is classified Euroclasse A1 and A2s1d0, making it suitable for general use on condition that the specific design and installation rules pertaining to various buildings are respected.Ultimate load
Based on the following 2 criteria: safety factor for ruin > 2.5 and horizontal boom under load (deformation at centre less deformation at ledge < 1/100th of the distance between ledges).
For all other criteria, contact us (especially permanent deformation).Preparing buildings
The installation company must possess facade know-how. It must ensure that the system is used in compliance with the conditions and area of use described in this document.Ventilated cladding
VMZ Overlapping panel is installed on a wall-mounted framework as part of a ventilated facade that provides a healthy, durable solution for the building.
Ventilation of the facade must be ensured by an air gap of 2 cm minimum, situated between the insulation and the back of the overlapping panel, or between the brickwork and the back of the overlapping panel.
A perforated panel on the base trim is used to create entry to the air gap.Layout plan
Prior to installation, the contractor must draw up a precise layout plan to determine the positioning of the secondary framework elements and the precise quantity of panels required.
The design and installation of the framework will take into account constraints arising from expansion and local installation rules.Storage recommendations
The overlapping panels must be stored on their original pallet on a dry floor, in a ventilated sheltered area.
Installation of the framework is prepared by marking out (laser or tracing line) and must correspond to the layout plan provided by the architect. Once the vertical tracing is done, the brackets are fixed. The centre distance between rafters must not exceed 600 mm on the main building.
Mineral wool insulation is installed directly onto the substructure.
Rafters are then fixed on brackets.
Start installing VMZ Overlapping panel by installing a perforated base trim to create the entry of the air gap. It is important to ensure the base trim is horizontally aligned because it determines the correct position of the first row of panels
|The panels are installed from bottom to top and fit into each other easily with a clicking movement. The panels are fixed onto each rafter using screws or nails.|
The panels must be handled with care on the trenching knife to avoid deformation.
For transverse junctions, a trim splice plate is placed behind one end of the panel.
The film must be removed quickly in a single movement after completion of installation.
A range of universal zinc accessories is available and makes working on flashings easy.
