Excellent privacy protection for large windows...

Excellent privacy protection for large windows

To avoid glass breakage, it is imperative that you follow our installation recommendations in the product data section.

This best-selling self-adhesive spy mirror film protects you from prying eyes during the day with its silver mirrored (outward facing) side. You can continue to look clearly outside. At night, when the light is switched on, the reflection appears in a reduced form on the inside. The view from the outside to the inside is then possible again. This film darkens the room by a perceived 20-25%, which is already noticeable in rooms that are not naturally flooded with light.

In addition, this mirror film offers maximum heat reduction. You can choose between interior and exterior installation. You can find out which is the right one for your glazing under the Product Data tab.

Privacy function

  • annoying views from outside are effectively prevented during the day
  • You can continue to enjoy the view
  • the rooms darken somewhat due to the metallised surface

When does the spy mirror film work during the day?
The
spy mirror films only work as long as it is brighter outside than inside. When the light is switched on, you can look inside again. The same is true if, for example, there is light coming in through a window on the opposite side. In order to provide privacy, it must therefore be darker inside than outside. In all other cases, it is possible to look in and even difficult to look out, as the reflection is always to the brighter side.

Sun protection function

  • Glare from the sun's rays is effectively reduced
  • Achievement of maximum heat reduction, especially noticeable with south-facing windows
  • Rejection of solar energy is 78% (interior installation) or 82% (exterior installation)
  • enormously high UV protection of approx. 99% (interior installation) or 95% (exterior installation)
  • fading of furniture and carpets is reduced

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.

Technical data and information at a glance...

Manufacturer's warranty

The manufacturer grants a guarantee of 7 years on the spy mirror film for interior installation. For the 5-year film for external installation, this guarantee is 5 years for vertical installation and 2 years for sloped glazing (skylights) from a roof slope of 25°. With the 8-year film for outdoor installation, the edges must be sealed all around. The guarantee is then 8 years for vertical installation and 5 years for sloped glazing (skylights) from a roof pitch of 25°. This guarantee refers to flaking, yellowing and demetallisation of the film.

Durability

The durability of the films for interior installation is up to 15 years, depending on various factors. For outdoor installation, a durability of up to 7 years is considered realistic for the 5-year film and 10 years for the 8-year film.
In the case of external installation on sloping glazing such as skylights with a roof pitch of 25° or more, this durability is reduced accordingly due to the stronger solar radiation and the higher exposure to environmental influences.

In the case of horizontal glazing or sloped glazing (skylights), it is imperative to choose external mounting. The pane should also be provided with edge glazing. For this purpose, we offer the matching neutral siliconeor as edge sealing set with joint filler. To avoid glass breakage, the entire pane must always be coated with this film; partial coatings are not permitted.

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 in place while the 2nd person starting from the corner, and at the same time spray the adhesive side of the 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 on the glass, the film should slide back and forth well, otherwise spray the glass again.
  6. Now spray the other side of the 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 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 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 , which is something to avoid.

Can I apply the 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:
Ich würde gerne ihre Folie von Innen an meiner Eingangstüre anbringen, die aus einer kompletten Glasfront besteht. Mein Vermieter hat vor kurzem eine neue Deckenlampe installiert, die so hell ist, dass man in meinem Flur alles sehen kann. Mein Flur ist tagsüber und abends sehr dunkel, da nur die Eingangstüre eine Lichtquelle ist und durch den Seiteneingang generell nicht viel Tageslicht rein scheint.
Meine Frage: wenn es im Flur absolut dunkel ist und draußen das Licht angeht, bleibt der Spiegeleffekt trotzdem erhalten? Mir ist klar, dass er z.B. nicht wirkt, wenn ich im Flur das Licht anhabe.
am 17. October 2022
Answer:
Wenn es bei Ihnen im Flur absolut dunkel ist und draußen vor der Tür im Hausflur das helle Licht angeht bildet sich auf der Hausflurseite der Folie eine Spiegelung. Wenn Sie selbst innen Licht anmachen hebt das den Spiegeleffekt wieder auf.
Um einen Sichtschutz zu gewähren, muss es somit innen dunkler sein als außen. Wenn auf beiden Seiten kein Licht an ist kann sich physikalisch bedingt auch keine Spiegelung bilden.

Question:
Ich habe im Souterrain ein Büro. Das Fenster ist 128 cm x 78 cm. Ich müsste auch tagsüber das Licht einschalten. Bringt die Spiegelfolie dann noch den gewünschten Effekt?
Pollmann G. am 23. October 2022
Answer:
Die Spionspiegelfolien funktionieren nur, so lange es draußen heller ist als innen.
Bei eingeschaltetem Licht kann man wieder hinein schauen. Das gleiche gilt auch, wenn z. B. durch ein Fenster auf der gegenüberliegenden Seite Licht einfällt.

Question:
Kann auch nur die (untere) Hälfte eines mannshohen Fensters beklebt werden?
Frank A. am 29. October 2022
Answer:
Nur wenn das Fenster keiner direkten Sonneneinstrahlung unterliegt geht es problemlos!
Andernfalls besteht ein Risiko da sich die folierte / unfolierte Scheibenhälfte unterschiedlich stark aufheizen. Dadurch entstehen Wärmespannungen im Glas die zu Glasbruch führen können.

Question:
Kann die Folie auch auf Plexi bzw. Acrylglas geklebt werden?
Marcus G. am 01. November 2022
Answer:
Das geht auch, alle Oberflächen die ähnlich glatt wie Glas sind eignen sich für eine Folierung mit Fensterfolie.

Question:
Wenn nur die Hälfte des Fensters beklebt werden soll, ist es besser die Folie innen anzubringen oder lieber außen?
Frank A. am 01. November 2022
Answer:
Als Montageseite empfehlen wir in dem Fall die Innenmontage weil sich dann kein Regenwasser oder Schmutz an der oberen Folienkante ansammeln kann.
Generell Achtung: Fenster die der vollen Sonneneinstrahlung ausgesetzt sind sollten nur vollflächig foliert werden da sonst die Gefahr vor Glasbruch besteht!

Question:
Reflektiert die Spiegelfolie die Sonne stark, weil gegen über die Fenster sehr nach liegen? Dankeschön für ihre Antwort :)
Veronika F. am 29. November 2022
Answer:
Die Folie reflektiert die Sonnenstrahlen stark zurück. Wenn der Winkel des einfallenden Sonnenlichts passt wird Ihr Gegenüber kurzzeitig geblendet bis die Sonne weiter gezogen ist.

Question:
Wie ist das mit der Temperaturentwicklung zwischen den Glasscheiben bei einer Dreifachverglasung? Kann die Spiegelfolie trotzdem von Innen angebracht werden? Wie sehr heizt die innen angebrachte Spiegelfolie die beiden Zwischenräume auf?
M. Daniel P. am 20. January 2023
Answer:
Die Temperatur des Luftraums zwischen den Glasscheiben würde deutlich ansteigen. Daher sollte bei einer Dreifachverglasung eine Spionspiegelfolie generell nur von außen angebracht werden!
Eine Innenmontage kann nur vollzogen werden wenn die Scheibe nicht in der Sonne liegt (z.B. bei Richtung Norden verbauten Fenstern).

Question:
Kann die Folie nach der Entfernung erneut angebracht werden oder muss diese verworfen werden?
Daniel N. am 25. January 2023
Answer:
Bei selbstklebenden Folien wie dieser Spion-Spiegelfolie härtet der Kleber nach der ersten Anbringung aus und kann nach einer Demontage nicht erneut Klebkraft aufbauen. Die Montage ist daher nur einmalig möglich.
