The Interlocking Panel System can be installed as either a vertical or horizontal system. Each panel is connected by the use of an interlocking groove giving the elegant appearance of a recessed joint. The panels are secured with concealed clips or screws concealed within the inside edge of the groove. Fixing method is dependent on size of panels. The Interlocking Panel System is suitable for exterior and interior applications. 

Key Advantages


The Interlocking Panel System can be installed horizontally or vertically and by using different panel sizes and playing with the seam height the designer has many facade design options. Suitable to all surface aspects including Zinc, Copper, Stainless Steel, Aluminium, colour coated products.

Greater Structural Stability

Interlocking System requires a heavier (1mm-2mm) gauge material and is installed over aluminium top had substructure. This ensures the flatness of the panels and gives the system overall more structural stability.

Thermal Expansion

The Interlocking Panel System allows for thermal expansion in the panel joints and clips.

Elegant Aesthetic

The panels are connected by use of an interlocking groove giving the elegant appearance of a recessed joint.  The transverse aluminium supporting structure also ensures a flat finish and smart linear façade.
