This self-adhesive sun protection film in Blue Dark combines effective heat protection with a striking, blue-metallic appearance. With only 12 % light transmission, it significantly darkens the room while rejecting 72 % of solar energy. The blue mirror effect gives the facade a modern, eye-catching look and provides reliable privacy during daylight hours.
Features at a Glance

- 12 % light transmission – strong darkening, ideal for intense sun exposure
- 86 % less glare – relaxed screen work without disturbing light reflections
- Blue metallic mirror effect – striking appearance with daytime privacy
- Durable surface – long-lasting and easy to clean
- Self-adhesive – simple installation without specialist knowledge
- 10-year warranty – against discolouration or peeling
Mirror Effect and Privacy
The blue coating creates a striking, metallic blue mirror effect on the exterior side of the window. From outside, the blue reflection of the surroundings is visible, while the view from inside remains unobstructed – albeit slightly tinted with a blue colour cast.
Important: The mirror effect always works on the side with the stronger light. During the day, the film mirrors outward and provides privacy. In darkness with interior lighting switched on, the effect reverses.
Suitable Glazing Types
This film is intended exclusively for interior installation on flat single glazing.
- Single glazing – yes
Not suitable for insulating glazing, low-E glass, tinted glazing or laminated glass.
For double glazing or other glass types, we recommend the Sun Protection Film Blue Dark for Exterior Mounting, which is suitable for additional glazing types.
Installation
The film is applied from the inside onto the cleaned glass surface using water and the included mounting kit. Partial installation is not possible with this film – it must cover the entire glass surface.
Warranty
10 years against discolouration or peeling when applied to vertical surfaces.
Variants
For exterior installation, the Sun Protection Film Blue Dark – Exterior is the right choice – also suitable for roof windows and angled glazing.

Warnings and safety information
- Do not apply interior films to insulating glass or thermal insulation glass. There is a risk of thermal glass breakage. Check the type of glass before installation and ask us if you are unsure.
- Keep film, backing paper and packaging away from babies and small children. If they cover the airways, there is a risk of suffocation.
- Cutting the film involves utility knives and sharp blades. There is a risk of injury, keep tools out of the reach of children.
- Installing film on exterior surfaces or at height involves a risk of falling. Work from a secure footing or hire a specialist company. For roof windows we generally recommend installation by a specialist company.
