What is the Interlocking Panel technique?
The Interlocking Panel system is a wall cladding system installed with a ventilated air space. It involves laying interlocking panels on a metal framework fixed to the supporting structure (masonry or metal structure). The panels are simply connected by the use of an interlocking groove giving the elegant appearance of a recessed joint. They are fixed onto the framework using the clips provided which are concealed in the inside edge of the groove.
|Centre-to-centre distances||From 200 mm to 300 mm|
|Weight* Kg/m²||11.18 kg/m² - 9.85 kg/m²|
|Length||0.5 to 6 m (horizontal) - to 4 m (vertical)|
|Joint width||From 5 mm to 20 mm|

- All flat facades. On vertical walls (slope 90°) and soffits.
- Can be used for both exterior and interior applications.
The substructure (not supplied) can be either galvanized steel or aluminium rail.
Rail spacing: maximum of 600 mm apart.
Load bearing structure
It can consist of:
- Masonry or reinforced concrete wall
- Main steel framing (Please consult VMZINC).
The panels can be laid vertically or horizontally. The choice of direction implies different aesthetics and technical solutions for the main flashings.
This dimension must be determined before establishing the layout and must be indicated when the panels are ordered.
Panels are fixed directly on wood or metal transverse purlins spaced a maximum of 600 mm apart.
A continuous 20 mm (minimum) ventilated air gap is left clear behind the boarding on the entire facade.
Installing Horizontal Panels:
The panels are laid from top to bottom in horizontal rows, with the groove less side up.
- Fitting the upper part of the facade:
|First fix a strip for folding down onto the framework, then check that the apron will overlap the interlocking panels by 30mm.|
|Fix the first row of panels at the top of the facade using 4 screws located in the central zone fixed area, cover the screws with the folded strip, then fix the lower part (edge with grove).|
|When the first row of panels is fixed onto the support, lock the second row down into the groove of the upper panels. Each clip is slid to the bottom of the groove of the upper panel then fixed onto the secondary framework.|
- Vertical transverse joint:
An element of the framework must be aligned with each vertical joint between the panels. The framework must ensure a minimum support of 100 mm. A flat inverted slider with two 15 mm folds is first fixed onto the framework to ensure that the transverse joints are watertight.
The interlocking panels are laid over it.
- Fitting the bottom part of the facade:
First lay a folded flashing strip on a galvanized steel corner piece, then the last row of panels.
Installing Vertical Panels:
Vertical panels are laid from bottom to top. The interlocking direction must be defined by the layout. Laying usually starts at the corner of the building.
|The groove less side of the panel is fixed first, opposite to the laying direction. Fix the upper section of the panel to the framework, using 4 screws located at the top of the panel.|
|Clips are fitted to the longitudinal joint between two adjoining panels as for horizontal panels.|
- Transverse joint:
Two types of transverse joints are possible:
- Horizontal joint: after laying the lower panels, an apron is fixed on the installed framework to overlap them by 30 mm. The upper panels are then laid.
- Interlocking joint: in order to obtain an invisible transverse joint, carefully cut back the grooves of the overlapping panel with shears, to ensure a 50 mm overlap of the panels.
VMZINC is the renowned international brand name of rolled zinc products. At VMZINC, we manufacture as well as market rolled zinc and pre-formed products that have five prime areas of application:
- Rainwater systems & Accessories
- Ornamentations And Decoration
Interlocking Panel is an integral part of the rain screen zinc wall cladding. It is installed with a ventilated space and can be installed as a horizontal or vertical element. Every panel is coupled with the use of an interlocking groove that offers a graceful appearance of a recessed joint.
VMZINC interlocking panel system is suitable for exterior and interior applications.
Advantages of Interlocking Panels
VMZINC makes use of the apt material option: Zinc titanium alloy that can be recycled or produced from recycled material. With adaptable and versatile qualities, it is an ideal solution for traditional as well as contemporary buildings.
Elegant Appeal: The panels are connected by the use of an interlocking groove giving the elegant appearance of a recessed joint. The transverse aluminum supporting structure which is covered by zinc capping also ensures a flat finish and smart linear façade. VMZINC Interlocking panels are fixed to aluminum framework using concealed mechanical fixing
Adaptability & Sustainability: Interlocking Panel System can be installed horizontally or vertically while making use of various panel sizes and depth of the panel. The designer has many facade design options. For Tapered or Diagonal installation, kindly consult us at www.vmzinc.in.
Proven Façade System: Since its inception and until now, VMZINC has years of extensive experience in manufacturing of Interlocking Panel System for large projects & complex façade applications. This can be of great use for your building design application. Additionally, we provide all the drawing detailing & technical support from our Indian and international teams.
Customization: VMZINC offers customized interlocking panels as per the architect’s façade design with the help of its Indian and International technical design office.
Interlocking Panel Connection
The interlocking panels are connected with an interlocking groove, giving the stylish look of a recessed joint. And they are fixed onto the framework using mechanical fixings, which are concealed in the joint. Though, the system can only be used on even, vertical walls. If the building exceeds a height of 30 m, please contact us.
