The Complete Guide to Visibility in 2026
Your facade is often the first thing people see of your business. Even before they step inside, they form an impression: professional, reliable, creative, or perhaps discreet. Facade advertising plays a bigger role in this than many business owners realize. It's not a standalone expression, but an integral part of your brand and your building.
Box letters Box letters are one of the most popular forms of facade advertising. They are durable, flexible in design, and suitable for virtually any type of building. This guide explains how box letters work, the available options, and what to consider for design, permitting, installation, and maintenance.

Box letters are three-dimensional letters these letters are mounted individually on a facade. Each letter is individually produced and can be equipped with internal LED lighting. This creates depth, shadows, and often also illumination, resulting in a strong and professional appearance.
Box letters are often used as a company name, logo or facade text and are suitable for both modern and classic buildings.
The sign industry uses fixed profiles. These profiles determine how a box letter is constructed and how light is visible.
With this profile, the lighting is located on the back of the letter. The light shines against the facade, creating a soft glow around the letter. This creates a calm and elegant effect and is often used in offices, hotels, and architectural buildings.
A classic profile where the letter has a distinct edge. This type is often chosen for traditional buildings or when a robust appearance is desired.
Here, the light shines forward through the front of the letter. This ensures maximum visibility, even from a distance. Profile 5 is often used in shops, restaurants, and buildings along busy roads.
These letters are completely translucent. Both the front and the sides illuminate. The result is sleek, modern, and very striking. This profile is a perfect fit for contemporary brands and new buildings.
If you're unsure whether to choose direct or indirect light, it's worth considering these options side by side in relation to your facade, surroundings, and corporate identity.
The material determines not only the appearance, but also the lifespan and maintenance.
Aluminum
Aluminum is the standard for facade advertising. It's lightweight, rustproof, and easy to coat in virtually any RAL color. Practical, durable, and widely applicable.
RV
Stainless steel is the choice when appearance is paramount. Think brushed steel, gold tones, or silver. This material is often used in high-end brands and prestigious buildings.
Acrylic
Acrylic is primarily used when light plays a significant role. It transmits a lot of light and provides bright, even illumination. Ideal for profile 8 and other full-illumination applications.
The right choice of material depends on location, desired appearance and maintenance level.
Neon is becoming less and less common. That's no coincidence. LED lighting is more energy-efficient, safer, and lasts considerably longer. LEDs are also easier to control in terms of light color and intensity.
Modern LED modules consume little power and can be easily connected to timers or light sensors. This makes facade advertising not only visible but also manageable.
Color temperature is a key consideration. Warm white around 3000K feels welcoming and luxurious. Cool white around 6500K looks professional and sleek. The right choice aligns with your brand identity and the building's surroundings.
In many cases, an environmental permit is required for facade advertising. Municipalities assess applications based on aesthetic requirements. This involves considering size, placement, light intensity, and the appearance in relation to the building and its surroundings.
Stricter regulations often apply to listed buildings or within historical areas. Light pollution also plays an increasingly important role in assessments.
A permitting process can take several weeks. Starting too late risks delays or rejection. Good preparation and clear drawings make all the difference.
A good design depends on neat installation.
A good design depends entirely on neat installation. Box letters can be mounted on rails or spacers. Rails ensure fewer drill holes and a clean line. Spacers create a floating effect and enhance the shadow effect in indirect lighting.
Accessibility of the facade determines how the installation is carried out. Consider the use of aerial platforms, scaffolding, and safety measures. Cabling also requires attention. Invisible cabling ensures a clean final look and prevents clutter.
The price of box letters varies per project. There are no fixed amounts, but there are fixed factors that determine the investment.
The size of the letters plays a significant role, as does the font. Delicate shapes and complex fonts require more work than clean lettering. The type of lighting, the mounting height, and the building's accessibility also play a role.
Facade Advertising it's a one-time investment with a long lifespan. Well-made box letters often last ten years or longer. When you weigh those costs against years of visibility, the value quickly becomes clear.
Box letters require little maintenance, but they are not entirely maintenance-free. Periodic cleaning prevents contamination and preserves their appearance. In some cases, an anti-spin treatment is applied.
LED modules have a long lifespan, but replacement may be necessary over time. Proper maintenance prevents malfunctions and ensures consistent lighting.
Facade Advertising is always customized. It's not just about writing on a wall, but about visibility, recognition, and the look and feel that suits your organization and building.
If you want to know what the best solution is for your situation, that starts with careful observation, thinking along and designing. Light boxes could also be a very suitable option for you.
