How is projection glass installed?

From the first appointment to the first projection: the seven-step process

Anyone considering a digital solution for their facade often thinks of construction sites: scaffolding, dust, closed retail spaces. With projection glass, the opposite is true – the installation is among the most unobtrusive in the field of digital media because the existing glazing remains intact.

This article describes the typical progression of a project – step by step. These steps are carried out by a trained Lumerax partner from your region: a window film installer, glazier or sign maker who has completed training on the system.

Step 1: Site analysis

It starts with an on-site appointment. The glass surfaces (size, structure, coatings), the spatial situation behind the pane, potential projector positions, power supply, and network connectivity are checked – as is the ambient light in the evening, which determines the design of the projection technology.

Equally important are content-related questions: What should the surface show? For whom? At what times? The answers determine the surface layout and system size.

Step 2: Measurement

After confirming basic feasibility, precise measurements are taken. Each pane is measured to the millimeter – including frames, mullions, and any drill holes or fittings.

On this basis, the film is cut precisely to size. The partner either cuts it in-house or has it delivered made to measure. Accurate measurement is the prerequisite for the film sitting on the surface later without edges and free of bubbles.

Step 3: Film installation

The projection film is installed on the inside of the glazing – comparable to the processing of high-quality window films, but with an additional electrical connection.

The pane is thoroughly cleaned, the film is precisely positioned and applied across the entire surface. Subsequently, the connecting edges are discreetly wired and connected to the control unit, which manages the switch between the transparent and projectable state.

For a typical shop window, this step is completed in one working day; the shop can generally remain open.

Step 4: Projector installation and alignment

In parallel or subsequently, the projector is installed – usually on the ceiling of the interior, occasionally on trusses or in special housings. The position follows the plan from the site analysis: image size, projection angle, and beam path must match without crossing walkways.

Then, the device is mechanically aligned until the raw image completely covers the target area.

Step 5: Calibration

Now comes the fine-tuning. Using software, the image is precisely mapped to the glass surface: distortion correction for oblique projection angles (warping), pixel-perfect masking of the edges, and color and brightness adjustment. For multi-projector systems, the individual images are seamlessly merged (blending).

The result of the calibration determines whether the projection appears like a native screen – this is where professional installation is distinguished from improvisation.

Step 6: CMS setup

With the technology in place, the system is ready – but the control is missing. The Content Management System is set up, allowing operators to upload content, create playlists, and define schedules.

A fully automatic system is typical: transparency mode and projection operation alternate based on time or dusk, and content runs according to a weekly schedule. After setup, regular operation runs without any on-site intervention.

Step 7: Training and handover

Finally, the team is instructed: uploading content, adjusting schedules, checking status – in modern systems, this is a matter of minutes and can be mastered without prior technical knowledge.

With the handover, the operator receives documentation, access data, and a dedicated contact person: their local partner. From this moment on, the facade is a medium in regular operation.

How long does it all take?

The most frequent surprise for clients is the timeframe: for a shop window project, there are typically a few weeks between the order and the first projection – determined primarily by the customization of the film. The on-site work itself takes one to three days, depending on the size.

Compared to structural alterations, this is a minimal intervention – without scaffolding, without approval procedures for structural changes, and without downtime.

Conclusion

A projection glass installation is a plannable, short, and operationally friendly process: seven steps from analysis to training, a few days on-site, no change to the architecture.

Your project is carried out by a trained Lumerax partner in your region. They advise you, plan the surface, install the film, put the installation into operation and remain your point of contact. Lumerax supplies the matched components – film, technology and controls – and trains its partners to a uniform standard.
