UV Protection Film Shields Against Fading

This transparent UV protection film is used wherever fading of furniture, clothing, carpets, or display items should be effectively slowed down. The film reduces fading by a factor of 3-4. Its very high UV protection of approximately 99.5% ensures the color fidelity of your items. Glass remains clear and transparent even with the film applied.

Effective 99.5% UV Protection

Effect range of our UV protection films
Effect range of our UV protection films

A UV protection film primarily blocks the strongly penetrating UVA and UVB rays with wavelengths below 380 nm, protecting the objects behind from fading.

The graph on the left shows the measurement results of our UV protection film for wavelengths between 250 and 1000 nm. The curve indicates that UV rays up to 378.1 nm are blocked 100%. Beyond that, UV transmittance increases. This results in a 99.5% UV protection. High-quality UV protection products achieve over 99% shielding, whereas conventional films usually barely reach this.

Theoretically, rays with wavelengths > 378 nm can still affect objects behind the film. A 100% protection cannot be guaranteed. An effective UV protection film can slow fading by a factor of 3-5.

Sun Protection Function

Additionally, this window film provides some heat protection, as sunlight is slightly reduced. Total solar energy rejection (reduced radiation at the glass) is 14%. However, the decisive factor is the unmatched UV protection of about 99.5%, which is even slightly higher than standard sun protection films.

Protection Against Bird Strikes

Effects via UV Absorption

UV-absorbing window surfaces create a “color tint” in reflected or transmitted areas, helping birds avoid those parts. Partial UV-absorbing areas create contrast with reflective or transparent sections, making the window partly tinted or reflective, allowing birds to perceive the glass during approach.

Effects via UV Reflection

If a bird perceives the UV-reflective window as mostly transparent (not reflective), the reflected UV image overlays the transparent area, discouraging the bird. If perceived as reflective, UV reflection can appear less effective. Partial UV-reflective areas create a “color contrast” or “reflection contrast” against otherwise reflective sections. Parallax during approach allows the bird to perceive the glass.

Our Installation Recommendation for Maximum Bird Protection

For optimal protection, we recommend applying the film in multiple strips on the window, e.g., horizontal 5cm wide strips. After the first strip, leave a 5cm gap, then apply the next strip. Repeat this pattern until the window is fully covered.

UV protection and actinic keratosis

Actinic keratosis is primarily caused by long-term exposure of the skin to UV radiation and is considered a potential precursor to squamous cell carcinoma. According to the product measurements, our transparent UV protection film filters approximately 99.5% of UV radiation and can therefore significantly reduce UV exposure behind glazed surfaces. The film is not a medical device and does not replace other sun protection measures or professional medical advice.

Included in delivery

You should definitely order the Transfer concentrate, item no. 020010, separately. It makes assembly easier and leads to a better result. Alternatively, you can also use a pH-neutral cleaner.

Any waste is not included in the scope of delivery.

Technical Information

Manufacturer's guarantee

The manufacturer grants a 10-year guarantee on this UV protective film for vertical installation and for sloped glazing (skylights) with a roof pitch of 25° or more. This guarantee covers peeling, yellowing and demetallisation of the film.

Durability

Depending on various factors, the durability of the films is up to 14 years in Central Europe. In the case of sloped glazing such as roof windows with a roof pitch of 25° or more, this durability is reduced accordingly due to the stronger solar radiation and higher exposure to environmental influences.

The durability of this film for external installation is 2 to 3 years in Central Europe, depending on various factors.

Installation recommendation

Based on technical data and extensive experience, we can recommend installation on the following vertically installed glass types:

These recommendations can still lead to glass breakage due to various factors at the installation site. According to our Terms and Conditions, Section 10, Paragraph 3, we assume no liability for this.

What our customers say

Customers find the Velken UV-protection film effective, clear and well packaged, with fast delivery and helpful instructions. Installation is generally straightforward but benefits from two people, practice and plenty of liquid; large panels can be tricky and some report bubbles, statics or dust.

Problemlose Verarbeitung

Montage hat problemlos geklappt, Folie ist nahezu unsichtbar. Das Anleitungsvideo ist super! Für die Montage größerer Flächen ist der Profi-Rakel zu empfehlen. Kann die Folie ohne Einschränkung empfehlen!

Wenn die Folie als Schutz vor Vogelschlag dienen soll, beklebe ich letztendlich (streifenweise) nur die halbe Fensterfläche, richtig?

Die Formulierung in der Beschreibung „bis die Scheibe komplett foliert ist“ verunsichert mich etwas.

Sie schreiben, dass die Folie das Ausbleichen um ca. das 3-4-fache verlangsamt. Kann man zwei Schichten Folie übereinander legen?

Würde das zu einem Faktor von 6-8 führen?

Ich habe die Folie (ca. 130x86cm) heute wie vorgesehen montiert. Bei mir haben sich jedoch einige unschöne Schlieren gebildet. Verschwinden diese noch oder habe ich etwas falsch gemacht (z.b. zu viel Transferflüssigkeit verwendet)?
