Questions and answers
Indoor installation or outdoor installation?
The following applies in principle: For modern windows installed after 1995, only external installation is recommended! Please ask for possible exceptions during an expert consultation with Velken customer service.
Advantages of internal installation
- The film is protected from the weather, which increases durability.
- It is cheaper than the variant for outdoor installation
Advantages of outdoor installation
- External mounting offers the advantage of higher efficiency (approx. 4%) compared to internal mounting.
- Sun protection films can also be installed on the outside of modern windows.
- Films are resistant to the weather due to an additional protective layer.
What are the benefits of a sun protection film?
Sun protection film reduces the indoor temperature and leads to a better feeling of well-being. Air conditioning costs can be saved. Depending on the type of film, the efficiency of the sun protection as well as the light transmission varies.
How good are sun protection films?
Sun protection films are as good as the strength of their reflection. The more pronounced the reflection, the higher its efficiency and thus also the total energy rejection. So the coolest is with a strongly or darkly mirrored sun protection film.
What does sun protection film cost?
Sun protection film costs between 26.90 €/m² to 38.90 €/m². The price difference depends on the selected film type.
We calculate the price exactly according to the entered film size in width x height. In this way, no superfluous material is purchased and the price is lower!
How do I get the sun protection film off again?
To remove a sun protection film, grasp it at one corner and then slowly pull it off at a wrong angle. In the case of adhesive films, the film can be warmed up beforehand with a hair dryer to dissolve the adhesive. Any adhesive residue after removing the sun protection film can be easily removed with our adhesive residue remover.
How do I care for my sun protection film?
Recommended:
- The sun protection film must not be cleaned during the first three weeks after application.
- Commercially available glass cleaning agents can be used.
- Clean the windows with soft cloths or a chamois leather.
- Make sure that rubber wipers and all other cleaning utensils are clean.
- Please clean film edges carefully.
- Therefore, clean an externally installed film at short intervals so that the hard dirt particles cannot settle too firmly on the film surface.
- In the case of externally laid films, coarse dust and dirt should be removed from the film with a very wet, soft chamois leather and sufficient clean water.
Cleaning:
- Spray the window surface with the water - cleaner mixture.
- Wipe off water with a rubber wiper from top to bottom.
- Soak heavily soiled areas again and clean with soft chamois leather or sponge and plenty of water.
- Spray the window again with a water-cleaner mixture and wipe off with a squeegee from top to bottom.
Not recommended:
- Do not use abrasive cleaning agents
- Never clean the panes dry.
- Do not use glass scrapers, razor blades or Scotch.
- Do not clean with high-pressure cleaners or steam cleaners.
- In general, the application of advertising stickers to the film coating is not recommended.
- Always remember: The surface coating of the film is scratch-resistant, but not indestructible.
How does a sun protection film work?
The sun's rays bring solar energy in the form of heat to the window glass. The room behind it heats up. Thanks to the special coating of a solar control film, the solar energy is reflected back. Your room remains pleasantly cool even in record summer temperatures.
How long do sun protection films last?
Depending on the type of film, the installation side and the installation position, sun protection films last for many years. Durabilities of between 10 and 15 years are possible. Please contact us for an exact durability prediction. We will be happy to assess your situation.
How do I apply sun protection film?
Self-adhesive films have a transparent adhesive applied to the back, just like a sticker. On top of this is a protective film that must first be peeled off. Now the adhesive side and the pane are sprayed with water. Then the sun protection film is placed on the glass and the water is wiped out from under the film.
