Interlock Plank System - (IPS)

The Interlock Plank System is a precision-manufactured rainscreen solution that delivers a clean aesthetic, alongside straightforward installation for modern building envelopes. Our secret fix design eliminates visible fasteners, providing a sophisticated finish where the material qualities of the façade remain the primary focus.

Specifications

IPS

A seamless, high-performance façade system

Our Interlock Plank System is designed to create a consistent, uninterrupted external appearance. The male and female joint design ensures a secure mechanical connection between planks, which maintains a precise, uniform finish across the entire elevation.

We engineered this system for installation horizontally or vertically on an aluminium subframe, allowing for extensive design freedom in bespoke architectural applications. The top-down installation method simplifies build sequences and speeds up on-site construction.

Secret Fix Design

Mechanical fixings are hidden within the interlocking joint to remove visible fasteners, resulting in a clean, refined façade surface.

Top-Down Installation

This build sequence starts at the top of the elevation and interlocks each plank into the one below, which ensures a fast, accurate install.

Design Versatility

The system supports a wide range of face heights, lengths, and orientations, allowing solutions to be precisely matched to performance and budget requirements.

Tested Reliability

The IPS is CWCT tested and available in A1 and A2 fire-rated materials, providing verified safety and performance for high-rise buildings.

Horizontal Orientation

A refined architectural solution for linear plank façades that require clean horizontal lines and tight joint control.

Vertical Orientation

The same interlocking precision can be applied vertically to create height and visual interest on feature elevations.
