Retractable Blackout Tunnel for Testing Area


Stuart Canvas Group is proud to announce the successful completion of an innovative project for Uniper Technologies. The project involved designing, manufacturing, and installing a custom retractable tunnel tailored to meet Uniper’s specific requirements for a versatile blackout testing area.

Project Specifications

Client: Uniper Technologies
Purpose: Creation of a blackout area for engineering project testing
Dimensions: 7 meters wide, 5 meters long, 4.2 meters high
Materials: Galvanised steel and 650gsm fire retardant PVC

Design and Material Selection

Uniper Technologies needed to create a specialised and controlled environment to conduct various engineering tests. The primary requirement was a complete blackout area to facilitate precise lighting adjustments for machinery testing. The tunnel had to accommodate large machinery, necessitating the generous dimensions of 7 meters in width, 5 meters in length, and 4.2 meters in height.

To meet these requirements, Stuart Canvas Group designed the tunnel using durable galvanised steel for the framework, ensuring structural integrity and longevity. The covering material chosen was 650gsm fire retardant PVC, which is robust enough to withstand regular use while providing the essential blackout conditions.

Functionality and Accessibility

A key feature of the tunnel is its retractable design. This functionality allows the tunnel to be extended when in use and retracted when not needed, ensuring it does not obstruct the workspace. It also allows various seized machinery to be positioned within the space securely. The entire structure is mounted on wheels, making it easy to move and reposition as necessary, providing maximum flexibility for Uniper Technologies.

The retractable feature also facilitates easy access for large machinery. By retracting the tunnel, operators can move equipment in and out without hassle, streamlining the workflow and enhancing productivity.

Installation and Execution

The installation process was meticulously planned and executed by Stuart Canvas Group’s experienced team. Ensuring the tunnel was perfectly aligned and securely mounted was crucial to achieving the blackout conditions required by Uniper Technologies. The end result is a highly functional, adaptable, and durable testing area that meets all the client’s specifications.


This project exemplifies Stuart Canvas Group’s commitment to delivering customised solutions that meet the specific needs of our clients. By combining innovative design, high-quality materials, and expert installation, we have provided Uniper Technologies with a valuable asset for their engineering tests.
