A lot of light with little insight

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

This only slightly mirrored spy mirror film provides moderate protection from prying eyes during the day. This film is recommended for rooms in which it should still be as bright as possible and at the same time a not one hundred percent visual protection can be accepted.

Objects behind the window film can be vaguely recognised, although the reflection makes it much more difficult to see in. You can still look out clearly, the view is only slightly darker than with an unfoiled window.

No privacy protection at night

At night, when the light is switched on inside, the reflection appears in a reduced form towards the inside. The view from the outside to the inside is then possible again! Unfortunately, there are physical limits to what we can do here, so there is no spy mirror film that can guarantee privacy at night as well.

When does the spy mirror film work?
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 also applies if, for example, light enters through a window on the opposite side. In order to provide visual protection, it must therefore be darker on the inside than on the outside. In all other cases, it is possible to look in and even difficult to look out, as the reflection always appears on the brighter side.

In addition, this mirror film offers a high level of 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.

Difference to classic spy mirror film

Compared to ourstronger spy mirror film with maximum privacy protection/mirroring, incident daylight is better transmitted by this film, and the view is also darkened to a lesser extent. It feels like there is only a 10-15% loss of light. In comparison: the stronger alternative darkens by a perceived 25-30 %. On the other hand, it offers even more effective heat protection from the sun's rays due to its unrivalled high level of mirroring.

Advantages of this mirror film

  • good daytime privacy
  • high light transmission
  • High rejection of total solar energy (reduced radiation on the glass):
    • 65% for interior installation
    • 69% for outdoor installation
  • very high UV protection:
    • 99% for indoor installation
    • 95% for outdoor installation

The scratch-resistant surface of the peephole mirror 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.

Technical data and information at a glance...

Manufacturer's Warranty

The manufacturer gives a 10-year guarantee on the sun protection film for indoor installation. The edges of the foil for outdoor installation must be sealed all around. The guarantee is then 8 years for vertical installation and 2 years for sloping glazing (roof windows) from a roof pitch of 25°. This guarantee covers peeling, yellowing and demetallization of the film when installed in Central Europe.

Durability

The durability of the films for indoor installation is up to 15 years, depending on various factors. For outdoor installation, a durability of 10 years is considered realistic if the film is installed in Central Europe.

In the case of external installation on sloping glazing such as skylights from a roof pitch of 25° This durability is reduced accordingly due to the stronger solar radiation and the higher exposure to environmental influences. This information only applies to the foils sealed overleaf in the area of external installation.

Exception for indoor installation:
If the pane is installed facing north and therefore does not get any direct sunlight, the spy mirror film can be attached inside regardless of the type of glass installed! In this case there is no risk of thermal stress

In the case of horizontal glazing, soundproof glazing or sloping glazing (roof windows), external installation should be selected. The pane should also be provided with an edge seal. We offer you the matching neutral silicone or as Edge sealing set with joint spatula. To avoid glass breakage, the entire pane must always be covered 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 eine Sichtschutzfolie auf ein Fenster anbringen. Es handelt sich um ein Doppelverglastes Holzfenster BJ72, die Scheiben wurden um 2004 neu gemacht. Mit dem Feuerzeugtest kam ich zum Schluss, dass es eine IsolierVerglasung sein sollte (Doppelte Flamme mit gleichbleibender Farbe). Bieten Sie hier eine Folie für an? Und was muss ich beachten damit es nicht zum "Glasbruch" kommt?
Michael M. am 08. January 2023
Answer:
Sie können die Spionspiegelfolie von außen anbringen (Variante Außenmontage bestellen). Um Glasbruch zu vermeiden sollte die Folie vollflächig angebracht werden.

Question:
Wenn es draußen dunkel ist und innen der Fernsehr läuft, kann ich raus sehen?
Suzann a. am 13. September 2023
Answer:
Es wird sich zumindest stellenweise eine leichte Spiegelung auf der Innenseite zeigen, die verhindert das man partiell raus schauen kann.

Question:
1. Wie lange hält eine Spiegelfolie, wenn sie außen angebracht ist und
2. ist es auch möglich nur 2/3 der Scheibe zu bekleben, damit im oberen Bereich noch mehr Licht reinkommt?
Alexandra G. am 22. November 2023
Answer:
Zu 1: Für die Außenmontage gilt eine Haltbarkeit von 10 Jahren als realistisch, wenn die Folie in Mitteleuropa montiert wird. Auf Schrägverglasungen wie Dachfenstern ab einer Dachschräge von 25° reduziert sich diese Haltbarkeit auf Grund der stärkeren Sonneneinstrahlung und der höheren Belastung durch Umwelteinflüsse entsprechend auf 3-5 Jahre.

Zu 2: Dies ist nicht anzuraten, zum einen weil dann der Sichtschutz stark gemindert wird und zum anderen weil es thermische Spannungen im Glas hervor ruft, wenn die Sonne darauf scheint. Wir raten daher nur zu einer vollflächigen Folierung bei verspiegelten Fensterfolien!

Question:
Wann wird zu einer Montage auf der Außenseite und wann zu einer Montage auf der Innenseite geraten? Wir haben Fenster, die ca. 2016 neu verbaut wurden.
Alina P. am 07. December 2023
Answer:
Bei Fenstern die nach 1995 eingebaut wurden und in der Sonne liegen empfehlen wir nur die Außenmontage. Andernfalls kann auch eine Innenmontage vorgenommen werden.

Question:
Kann die Folie nach der Montage bei Nichtgefallen einfach und rückstandslos wieder entfernt werden?
Wenn ja, würde ich gerne wissen, ob das bei Innenmontage auch noch nach mehreren Jahren möglich ist.

Kann die Folie wieder verwendet werden?
Heidi H. am 08. January 2024
Answer:
Die Folie kann ohne Rückstände oder Beschädigungen am Glas wieder entfernt werden.
Wenn sie viele Jahre auf der Scheibe saß können vereinzelt Klebereste zurück bleiben, welche einfach mit Seifenwasser eingeweicht und abgewischt werden können.
Für besonders hartnäckige Stellen haben wir optional einen Klebereste Entferner.

Question:
Wie verhält sich die Folie, wenn die Katze draußen am Fenster sitzt und rein will, und mit ihren Pfoten, vielleicht auch Krallen, an der Festscheibe kratzt. Hält das die Folie aus? oder doch lieber von innen bekleben? Fenster sind Bj. ungefähr 1990-1995.
Ramona W. am 26. April 2024
Answer:
Katzenkrallen können die Folie beschädigen, daher können Sie in Ihrem konkreten Fall die Folie auch problemlos auf der Innenseite anbringen wenn die Katze dort nicht kratzt.
