This burglary protection film offers the best possible protection against being thrown or broken...

This burglary protection film offers the best possible protection against being thrown or broken through thanks to its enormously resistant, triple-laminated structure. Possible burglars are no longer able to break in through the window pane with little effort.

This security film is typically affixed to the side facing away from the impact (usually inside installation). The A1 film should ideally be placed under the glass retaining bars to further increase the burglary protection. Alternatively, the film can be stuck right up to the window seal and the edge bond made by means of an edge sealant.

Advantages of this film:

  • material thickness 300 µm (12mil) attack-resistant thickness
  • fulfils DIN EN 12600, resistance class 1B1
  • Tested safety according to EN 356 P2A
  • Fire resistance class M1
  • Resistance structure 3-fold laminated A1 film
  • High UV protection (95%)
  • Avoids expensive replacement with safety glass

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

We recommend that you use the mounting squeegee with felt edge, art. no. 010150, with this film or the professional mounting squeegee, Float, for larger surfaces, art. No. 010190 for larger areas, as these make the application much easier.

Please ensure that this burglary protection film is applied no later than one week after receipt of the goods. Otherwise the film may be damaged from storage by remaining in the box. This is characterised by excessive twist, which means that the film can no longer be applied completely flat. It is also possible that air is drawn between the film and the backing material, resulting in visible stripes after installation.

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 guarantee

The manufacturer grants a guarantee of 10 years on this safety film when installed vertically and on sloped glazing (skylights) from a roof slope of 25°. This guarantee refers to flaking, yellowing and demetallisation of the film.


Depending on various factors, the durability of the films is up to 14 years in Central Europe. In the case of sloped 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.

This safety film meets the following standards / properties:
EN 12600 1B1, EN 356 P2A, fire resistance class M1, REACH - RoHS compliant.

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.

Assembly instructions for burglary protection films (self-adhesive)

You will need the following items

for larger areas, as these make the application much easier.

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
  3. . No dirt residues should remain on the glass!
  4. 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.
  5. Now hold the Burglary protection film in place while the 2nd person starting from the corner, and at the same time spray the adhesive side of the Burglary protection 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.
  6. Place the Burglary protection film on the glass, the film should slide back and forth well, otherwise spray the glass again.
  7. Now spray the other side of the Burglary protection film as well, this will make it easier for you to work with the mounting squeegee.
  8. 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.
  9. Carefully wipe the edges and the foil with a soft cloth. If necessary, press the edges again with the mounting squeegee.
  10. Now let the Burglary protection film dry for three days without touching it.
  11. 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 Burglary protection 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 Burglary protection film, which is something to avoid.

Can I apply the Burglary protection 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.

Immer wieder

Von der Bestellung bis zur Lieferung alles top. Maße passten genau. Die Qualität der Folie ist sehr gut und mit dem mitbestellten Montageset problemlos zu verarbeiten. Immer wieder gerne!

Einfache Handhabung, kleine Abzüge in der B-Note

Schnelle Auftragsbearbeitung, Folie kam ordentlich verpackt an. Verarbeitungshinweise sind detailliert und verständlich.
Es wäre prima, wenn es eine Markierung gäbe, auf welcher Seite die Schutzfolie montiert wurde. Das Mikrofasertuch aus dem Profi-Montageset ist zwar sehr groß, hat aber gefußelt. Wir waren froh, dass wir bei einer 2,0 m x 0,6 m Scheibe bei der Folienmontage zu dritt waren. Zwei haben die Folie an den Scheibenecken in Position gehalten, einer hat die Trägerflüssigkeit und Luftblasen mit dem mitgelieferten Rakel unter der Folie herausgestrichen.
Ob die Folie hält, was sie verspricht, finden wir im besten Fall nie heraus.

Tolles Produkt

Folie zügig geliefert. Ich als Rentnerin habe sie problemlos alleine anbringen können. Mit Ergebnis super zufrieden. Wohne im Erdgeschoss- da gibt die Folie schon zusätzliche Sicherheit, da in unserem Haus vor einiger Zeit eingebrochen wurde. Nur zu empfehlen.

Feedback nach 6 Monaten

Hallo, ich habe die Folie vor 6 Monaten angebracht. Auch nach dieser Zeit gibt es keinen Grund zur Beanstandung. Ursprünglich hatte ich sie als Hagelschutz vorgesehen, habe aber diesbezüglich noch keine Erfahrungen sammeln können und hoffe, dass sie im Falle eines Falles das Glas entsprechend schützt.

Top Lieferung und millimetergenau

Die Folie wurde gerollt und großzügig eingepackt geliefert. Die Dicke der Folie wirkt schon sehr hochwertig und aufgrund der Festigkeit der Folie lief die Montage bisher einwandfrei.

Vor der Bestellung habe ich noch den fachmännischen Rat von Herrn Siegel zum Thema Haltbarkeit, UV-Schutz, Verarbeitung usw. eingeholt, was mir bei der Kaufentscheidung sehr geholfen hat. Die beiden bestellten Fensterfolien (Ausführung 300 µm, klar) wurden innerhalb von 4 Tagen, perfekt auf Maß zugeschnitten, geliefert. Die Verarbeitung ist relativ einfach, man sollte auf absolute Sauberkeit der Fensterfläche achten. Die überschüssige Trägerflüssigkeit habe ich zum Schluss sorgfältig längs der Folie von oben nach unten mit dem beigefügten Rakel herausgedrückt (wichtig, dass keine Rückstände der Flüssigkeit unter der Folie verbleiben).
Ich habe die Folien als Hagelschutz für Dachfenster (Velux, ca. 25 Jahre alt) vorgesehen, als preisgünstige Alternative für neue, gehärtete Scheiben. Allerdings liegen Fa. Velken hierzu keine Erfahrungen bezgl. der Haltbarkeit gegenüber Hagel vor. Vlt. sollte man die Wirkung mal laborseitig gegenüber ungeschützten Fenstern testen lassen. Wäre bestimmt ein gutes Marketingargument. ;)

Übung macht den Meister

Wie immer schnelle und massgenaue Lieferung, nach den ersten drei Kellerfenstern sind die nächsten drei Fenster im Erdgeschoß fertig, ohne Blasen und Ränder.Auf eines sollte man noch achten,der Schneidgrat der teilweise noch an der Folie haftet sollte vor der Montage gründlichst entfernt werden.

Verarbeitung gut, Folie hält am Rand leider (noch?) nicht gut

Lieferung sehr schnell. Sehr gute Anleitung. Folien exakt zugeschnitten. Werkzeug top.

Fensterfolien freitags erhalten, Verarbeitung Sa und So.
Jeweils nach einem Tag fingen alle Folien an sich am Rand (ca. 2 mm nach innen) und besonders an den Ecken wieder abzulösen (hier über 1cm --> siehe auch Bilder): es steht zwar nichts hoch, aber man erkennt es deutlich.
Wir haben bisher nichts berührt und warten und hoffen, ob es doch noch hält, bzw. dass es sich nicht noch weiter ablöst.
An einen Montagefehler glaube ich nicht, da das Anbringen nach Anleitung wirklich gut funktioniert hat und die Folien anfangs auch komplett bis zum Rand klebten.
Ist vielleicht das Wetter zu warm?
(An dem abgebildeten Fenster auf den Fotos scheint allerdings keine Sonne hin.)

Manche Folien waren von der Klebeseite gesehen nach außen gerollt - diese waren etwas schwieriger anzubringen (andersrum wäre es besser), man sieht aber jetzt keinen Unterschied mehr, auch die anderen lösen sich am Rand. Wir haben insgesamt 7 Folien im Keller angebracht.
Wir wollen heute die zweite Fuhre Folien bestellen, nachdem wir jetzt im Keller üben konnten - vielleicht gibt es noch einen Tipp für uns!?

Wenige kleine Einschlüsse von letzten Schmutzresten oder Fusseln gibt es auch, aber das liegt daran, dass es kaum möglich ist, die Fenster lupenrein sauber zu kriegen trotz Klingen. Den Staub in der Luft kann man wohl kaum beseitigen. Das stört uns daher auch nicht weiter. Wir hoffen trotzdem auch da, dass sich die Folien noch ranziehen und die Stellen kleiner (oder zumindest nicht größer) werden oder verschwinden.

(Die Fotos sind teilweise stark vergrößert.)

Vielen Dank für die ausführliche Bewertung! Den abstehenden Rand konnten wir in einem Test reproduzieren. Dieser entsteht wenn der Folienkleber am Rand noch nicht ausreichend stark ausgehärtet ist. In dem Fall hilft nur die Folie immer wieder anzudrücken und somit dem Kleber zu unterstützen. Das Unterfangen kann sich einige Minuten hinziehen. 

Eine 100% staubfreie Montage lässt meistens sich nicht umsetzen. Wichtig ist, dass das Fenster und der Rahmen nass abgeputzt werden. Dazu können Sie die Trägerfolie welche die Klebeseite abdeckt wie in der Montageanleitung beschrieben im Stehen abziehen. Denn anders als bei einem Entfernen der Trägerfolie auf dem Fußboden wird hierbei auch weniger Staub aufgewirbelt. Sprühen Sie die Klebeseite der Folie nachdem die Trägerfolie abgezogen wurde direkt mit der Flüssigkeit ein. Auch so vermeiden Sie, dass Staub auf der Klebeseite ansetzen kann.
