This blackout film, also called block-out film, is white on the inside as well as on the outside.

In addition to the visible light, the solar radiation is also reduced by this blackout film. The rejection of the total solar energy (reduced radiation on the glass) is 86%. In addition, there is the enormously high UV protection of about 99%. This reduces the heating of the rooms, the room climate becomes more pleasant, the energy costs for the air conditioning are reduced, the fading of furniture and carpets is reduced and the room is darkened to a very high degree. Only about 10% of the light penetrates this blackout film.

This film is always used when a permanent darkening of the room is desired or when, for example, triangular windows in bedrooms cannot be darkened with roller shutters.

The scratch-resistant surface of the blackout film makes it easy to clean with standard glass cleaners. It is dirt-repellent and easy to clean.

Included in delivery

You should definitely order the transfer concentrate, art. no. 020010 additionally. It makes the installation easier and leads to a better result. Alternatively, you can also use a pH-neutral cleaner. This must be pH-neutral to prevent streaks from forming together with the film adhesive!

Any offcuts are not included in the scope of delivery.

This blackout film should not be used with horizontal glazing or sloped glazing (skylights). In this case we recommend the blackout film for external installation, art. no. 412010.

These recommendations may still result in glass breakage due to various factors at the installation site. According to our AGB, §10 paragraph 3 we do not accept any liability for this.

Answers to the most frequently asked questions...

General questions

Can I get a free foil sample?

Of course, please click on this link to access the corresponding order form. You are welcome to add to the list of items if you wish. There are no costs for you!

Will you also cut the film for me?

We cut each film to the exact millimetre according to the dimensions you enter. The cutting is free of charge. You can find detailed instructions on how to measure your panes here.

Alternatively, you can also cut your film by hand with a cutter knife. However, this requires a little manual skill, so you are usually better off using our free service.

Can you also cut a round blank or other geometry?

In general, almost all 2D shapes can be produced. Many geometries (e.g. triangles, trapezoids, circles) can be ordered directly via the online shop. To do so, please click on the orange rectangle to the right of the article image. You can then choose between many different shapes.

For shapes that are not specified, please send us a small sketch (photo) in which you specify the side lengths, radii or angles. Please contact us for this purpose.

Does the film also adhere to surfaces other than glass?

The window film adheres to all surfaces that are approximately as smooth as glass. When applying the film to plastic, please bear in mind that the adhesive may bond with the plastic, making it impossible to remove the film cleanly later.

How can I clean my window pane with the film in place?

You can keep your window pane clean as usual. The film should not be rubbed with sharp-edged objects (e.g. a brush).
You can find more information in our guide General care instructions for window films.

Can the film be removed without leaving any residue?

All window films can be removed without leaving any residue and without damaging the glass surface!
Below you will find detailed instructions on how to remove old window films.

Can you also print on films?

Unfortunately, we do not currently offer foil printing and do not have any partner companies with whom we can realise foil printing.

Installation tips

  • Two people should carry out the installation!
  • Do not install any film at temperatures on the installation side below +6° C.
  1. Fill the spray bottle with 0.5 litres of water and add the transfer concentrate (30 ml) (enough for approx. 6 to 7 m² of glass surface).
  2. Thoroughly clean the glass with commercial or our glass cleaner!
    Remove all sticky particles (e.g. paint or fly dirt) preferably with the glass scraper blade. No dirt residues should remain on the glass!
  3. The sandblasting foil consists of the mostly white backing paper and the actual sandblasting foil.
    Now place the sandblasting foil with the view side down on the glass pane or similar. You are now looking at the back of the film.
    Then carefully and slowly peel off the backing paper at as shallow an angle as possible until it is about halfway along the entire length of the film. Cut the backing paper and stick it back onto the sandblasting film with a gap of about 2 cm to the remaining backing paper.
  4. Now hold the Blackout film in place while the 2nd person starting from the corner, and at the same time spray the adhesive side of the Blackout film that is now exposed with the liquid.
    Afterwards, the glass pane (surface to be pasted) must be sprayed with the liquid. Do not be sparing with the liquid, the film and pane should be well wet.
  5. Place the Blackout film on the glass, the film should slide back and forth well, otherwise spray the glass again.
  6. Now spray the other side of the Blackout film as well, this will make it easier for you to work with the mounting squeegee.
  7. Now press the liquid out evenly with the mounting squeegee from the centre to the right and to the left. Make sure that there is no residual water left under the film! Repeat this procedure several times to remove even invisible water residues. When doing this, wrap the supplied squeegee with a paper towel to avoid any scratches.
  8. Carefully wipe the edges and the foil with a soft cloth. If necessary, press the edges again with the mounting squeegee.
  9. Now let the Blackout film dry for three days without touching it.
  10. Wait two weeks before cleaning the film for the first time and never use hard objects (brush or blade) to clean it. Commercially available glass cleaners can be used.

FAQ`s about the installation

Can I carry out the film installation alone?

Films that are no larger than 1m² can be installed alone without any problems.
For larger pieces, it is recommended that two people carry out the installation. This makes it easier to handle the film and place it on the pane.

How can I avoid dust inclusions under the adhesive back side?

First, clean your windows really thoroughly with glass cleaner. Then go over the entire window pane again with our supplied glass scraper blade to remove any hard-core impurities on the pane (such as fly droppings). These fine stains are often invisible to the naked eye and you will be amazed at what the blade still removes.

In addition, do not lay the Blackout film after peeling off (covers the adhesive side for transport) on the floor to get it wet. Rather, pull a table nearby to spray the film on. On the floor you will always stir up very fine dust particles, which will then settle on the adhesive side facing upwards. These dust particles can later show up on the pane under the Blackout film, which is something to avoid.

Can I apply the Blackout film without transfer concentrate?

Alternatively, you should at least use a pH-neutral cleaner. We do not recommend installation without any additive at all, which increases the gliding properties of the water!

We strongly advise against the use of water diluted with detergent. This can lead to streaking due to a reaction with the film adhesive.

Does the film have to be applied perfectly to the glass at the first attempt?

No, this is not necessary as long as you have sprayed the adhesive side of the window film and your glass sufficiently wet. Due to the moisture, the adhesive has no adhesive effect, which makes it easy to move the film and position it precisely. It is even possible to remove the film from the glass again and reapply it.

After mounting, small bubbles formed the next day

The bubbles consist of residual liquid that was not pressed out from under the film when it was applied. Over time, these run down between the already drying film adhesive as far as they can under the film and collect in some places. The bubbles disappear by themselves when the remaining liquid diffuses through the film to the outside. Depending on the outside temperature and sunlight, this can take up to three or more weeks before the film fits like a second skin.

In any case, you should wait this time and do nothing. In most cases, the blisters disappear all by themselves!

How easy is it to remove the film?

The window film itself can be easily removed. To do this, detach one corner and fold it over directly. The film can then be removed from the glass at as flat an angle as possible.

It is possible that residues of the film adhesive remain in some places. These can be soaked with our adhesive remover or acetone and then removed again with a glass scraper or ceramic field scraper. You will find detailed instructions on how to remove window films on our homepage in the FAQ`s.

Question:
Wird der Raum durch die Folie komplett abgedunkelt oder wird ein Restlich durchgelassen?
Ist die Folie selbstklebend und wozu das Montageset? Ist die Folie auf den beiden Außenseiten weiß? (das wäre wichtig).
Ralf K. am 01. November 2022
Answer:
Der Raum wird gut abgedunkelt, es kommt nahezu kein Licht mehr durch die Folie durch. Das Montageset kann optional mit bestellt werden, falls man die Komponenten nicht im Haushalt zur Hand hat. Diese Verdunkelungsfolie ist selbstklebend und auf beiden Seiten weiß.

Question:
Kann man diese Folie auch auf Glasbausteinen anbringen? Wir haben zwei größere Fenster aus Glasbausteinen, diese haben keine glatte Oberfläche. Wir wollen die Sonneneinstrahlung verringern.
Andreas K. am 20. August 2023
Answer:
Die Folie wird darauf kleben bleiben, auch wenn die Kontaktpunkte gering ausfallen. Leider kann die Folie sich nicht gut dem unebenen Untergrund anpassen. Das Ergebnis wird optisch daher nicht perfekt aussehen.

Question:
Kann die Folie bei Bedarf auch ganz einfach wieder entfernt werden?
Andrea M. am 19. November 2023
Answer:
Die Folie kann einmalig wieder ohne Beschädigungen von der Scheibe abgezogen werden. Sollten vereinzelt Klebereste zurück bleiben, können diese zunächst mit Seifenwasser eingeweicht und abgewischt werden. Sollte danach wieder erwartend noch etwas übrig bleiben gibt es für härtere Rückstände unseren Kleberest Entferner.
