The Best Window Film: Our Choices
Buying and evaluation criteria for window films
In order to help you decide on the right window film, we have worked out some buying criteria below that could be relevant for your purchase decision. In this way, we would like to make it easier for you to choose the right window film for your home.
Criteria with which you can compare different window films are as follows:
When considering the dimensions of the window film to buy, it is important not to opt for products that are too small. Using a window film that is too small for a window that is too large can be dangerous, which is why it can make sense to opt for larger dimensions.
Especially when applying window film for the first time, it is very likely that mistakes will be made. In that case, an oversize material is very advantageous. In addition, the film can be easily adapted to one's own window with a cutter knife.
In the case of sun protection films, it is very important to cover the entire window with the film. Partial covering of the window can lead to glass breakage and tension on the window. This does not apply to other types, such as frosted glass film.
If you decide to use a window film for aesthetic reasons, decorative films are very suitable. These are now available in a wide variety of types, from matt to coloured window films to decorative motifs.
The most common colour for decorative films is white. They are usually either matt, transparent or mirrored. It is also possible to order personalised films and have them made to measure.
There are two types of window films: those with adhesive and adhesive films. For window films with adhesive, there is an additional film that is removed before application. Next, the film is sprayed with water and detergent and then attached to the window. To avoid air bubbles, the film must be smoothed.
Adhesive films can be applied without glue. The film adheres to the glass through the forces between the molecules of the film and the surface. Care must be taken to ensure that the surface to be covered is completely free of dust and dirt.
Light and irradiation conditions
Depending on the type of window film, the light and irradiation conditions are also relevant. With privacy films, for example, the view to the outside is completely unobstructed, while the view to the inside is prevented. Nevertheless, the difference in brightness is hardly any different when looking outside. Depending on the thickness of the privacy protection, the window can almost look transparent with the film.
There are different degrees of light transmission for sun protection films. However, most are completely transparent and do not affect the light transmission. They offer UV protection and protect furniture from fading, for example. Modern sun protection films, however, do not offer privacy protection.
When cleaning window films, it is important to use non-solvent cleaning agents. For example, scouring agents, cleaning petrol or edged tools can leave marks on the film.
Hot water and normal washing-up liquid are perfectly adequate for cleaning window films. An important detail is that a lot of water must be used to remove the loosened dirt. Otherwise the dirt particles act like sandpaper and can damage the window film.
Depending on how dirty the film is, this pass must be repeated, as no scrubbing or scratching is allowed. If cleaning is done too aggressively, small cracks can appear in the film, the water can get into these cracks and loosen the entire film.
Guide: Frequently asked questions about window films answered in detail
Who are window films suitable for?
They can also do a lot decoratively and provide burglary protection. Window films can be used both indoors and outdoors. Because they are easy to install, they are usually very attractive. However, care should be taken to apply the film thoroughly. They are used in many areas, such as medical practices, offices, swimming pools or even therapy rooms.
What types of window films are there?
- Privacy film
- Decorative film
- Sun protection film
- Security film
- Anti-vandalism film
- Cold protection film
Security films provide privacy protection by being opaque, while decorative films are used more for decorative purposes. They can also be customised, which makes them suitable for premises of different businesses.
There are also sun shades that reflect the sun's rays and thus offer UV protection. This can prevent the fading of furniture or clothing. Security films with splinter protection prevent burglars and reduce the risk of injury.
Another type of window film is cold protection film, which prevents the cold from entering the house and reduces heating costs.
What do window films cost?
Nevertheless, we will try to give you an overview below:
|Price range||Available products|
|Low-priced (20 - 40 €)||Privacy film for an approx. 100*100 cm window, also splinter protection film for small windows|
|Medium-priced (40 - 80 €)||Window film for large and old windows, tools are usually included with online orders|
|High-priced (from 80 €)||Purchase of window film by specialist company|
How can window film be removed?
In any case, the moisture should remain on the film for two to three hours. After the adhesive has dissolved, the film can be removed from the glass pane. A glass scraper can also be used to help.
Window films can be used for many purposes. Privacy protection, decoration, sun protection and protection against cold are some of them. Because they are so easy to install, anyone can do it themselves. When buying a window film, it is important that it is ideally purchased in a larger size so that the film can be perfectly adjusted afterwards.
In addition to the dimensions, the design, the installation options, the light and irradiation conditions and the cleaning are also important. Our research has shown that an average window film can be purchased for as little as 20 euros. However, the price depends greatly on the size required and the type of window film.
