Flatlock Cladding
Residential | Commercial
Flatlock
Flat Lock Panels are a basic yet elegant cladding technique that creates a horizontal or vertical flat seam akin to shiplap. On all four sides, the method uses a basic interlocking fold.
This approach is applicable for any structures up to 30 meters in height. The concealed clips are used to install the pre-formed panels.
Standard panel widths for Aluminium or Colorbond are 330mm, and for Zinc, they are 430mm. These are designed to minimize wastage owing to coil widths (wider panels are available but may result in distortion or oil-canning). The maximum panel length is 3 meters.
| Panel Sizing | Panel Length | sub-structure | Fire Rated |
|---|---|---|---|
|
140mm - 500mm |
Up to 4000 mm long panels (material dependant) |
15 mm construction grade substructure for wall cladding |
A
fireproof substrate will be required. |

Flatlock Features
- The panels are mounted on a minimum of 15 mm plywood.
- Between the panel and the plywood, anti-abrasive construction paper must be used.
- Behind the plywood, a constant ventilation air gap should be left unobstructed.
- However, with the inclusion of Proctor vapour membrane on the outside, the plywood -if wet- can dissipate moisture through the outer face and negate the gap at the back. This will allow plywood to be directly attached to a stud-frame.
- Hidden fastenings for that perfect appearance and recessed joints are features of flatlock cladding.
Available Materials
- Alluminium
- Brass
- Copper
- Steel
- Weathering steel (Corten)
- Galvanised steel
- Stainless steel
- Titanium Zinc
Limitations
- Flatlock and Recessed Flatlock require a minimum roof pitch of 25o when fitted as roof cladding.
- If you’re considering employing Flatlock in a non-standard application, check with Architectural Cladding Melbourne to make sure all of the elements are viable.
- Panel widths and lengths can be varied depending on the material.
Installation
Flat Lock Panel is a wall system that is made up of factory-formed panels that are custom-sized into rectangle, square, or diamond forms and have a created interlocking welt around all sides. They’re put together by engaging the bottom edge of each panel in the top edge of the panel below and mechanically fastening the panels to the supports with concealed clips hidden behind the upper edges of the panels.
Factory produced clips, fasteners, flashings, and finishing elements are all part of the system. The wind loading determines the distance between the concealed clips, which are typically separated at 300mm centers for residential buildings.
Recessed Flatlock Cladding
Residential | Commercial
For larger express joins, Recessed Flatlock can be used. Because the panel is folded with a recess and an additional layer of plywood below the recess, it provides a versatile solution with maximum resistance. Speak to our team at Architectural Cladding Melbourne to see if recessed flatlock is the right option for your project.
