Cold protection film for windows reduces energy loss in winter...

Cold protection film for windows reduces energy loss in winter

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

With this Low-E film, there is a 35% reduction in winter heat loss on single glazed windows and 25% on double glazed windows. The heat loss on foiled windows is significantly reduced, which in turn reduces the energy required to keep the heat out. This reduces heating costs and lowers the general CO2 emissions. The transparency of this insulating film is only slightly tinted and almost unrestricted compared to an unfoiled window.

Energy saving function

  • This film has a special coating that reflects the infrared rays that are in every heated room and want to pass through your window pane to the outside. This prevents the heat from being drawn outwards. In addition, the perceived coldness near the window disappears when you hold your hand in front of it. The heat reflection into the room is a remarkable 35 % on toughened glass. On double glazing it is 25%.
  • Another effect is that the dew point on your window pane is lowered. If, for example, your window pane starts to get damp at +1°C without the film, the dew point shifts downwards by -2 to -3°C with the cold protection film fitted. The pane would therefore only start to sweat at approx. -2°C. This temporarily saves you having to wipe the windows in the morning.

This window film is used wherever, in addition to winter heat loss and summer heat protection, the appearance of the building should not or must not be noticeably changed (museums or buildings that are listed).

The solar radiation is reduced by this energy-saving film. Thus, the rejection of the total solar energy (reduced radiation on the glass) is 58% with the film for interior installation.
In addition, there is the enormously high UV protection of about 99%. This reduces the heating of the rooms, the indoor climate becomes more pleasant, the energy costs for air conditioning are reduced, the fading of furniture and carpets is reduced and the building does not experience any visual change.

Explanation of the sun protection function

  • This insulating film lets the sun's rays into the room in winter, but does not let them through in summer. Since the sun is lower in winter than in summer, the sun's rays hit the film at a different angle. The coating is designed in such a way that the sun's rays are transmitted at a shallow angle and steeply incoming rays are reflected.

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

Not suitable for roof windows

This insulating film should not be installed on a skylight because of the necessary internal mounting. For windows that are tilted towards the sun, we recommend a silver mirrored sun protection film for external mounting.

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 provides a 5-year guarantee on this cold and energy-saving film. This guarantee covers flaking, yellowing and demetallisation of the film.

Erklärung von Lichttransmission, Reflexion, Absorbtion

The values of the properties were determined by the film manufacturer. They have been calculated on 3 mm glass using the appropriate methodology and are subject to variations in process conditions in industrial production. They are for estimation purposes only.

The following table shows the hemispherical emissivity e of the film as well as Ug-value of the combination of the film with different reference glazings:

Filmhemispherical

Double

without foil 0,84 5,8 2,7 1,3 1,1
Insulating foil 171010 0,33 +/- 0,02 4,3 2,3 1,2 1,1

The emissivity of 171010 is significantly lower than that of uncoated float glass, the influence on the Ug-value is clear for single glazing, and still noticeable for uncoated double glazing. For thermal insulation glazing, the influence of the low-emissivity coating on the Ug value is small.

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.


This film is not suitable for sloped glazing (e.g. skylights), as there is an increased risk of glass breakage.

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 Insulating films (self-adhesive)

You will need the following items

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

Can I apply the Insulating foils 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:
In meinem Badezimmer habe ich ein altes Velux Dachfenster von 1982 und möchte dort eine Isolierfolie auftragen, um Heizkosten zu sparen. Welches Ihrer Produkte können Sie mir empfehlen?
Moritz S. am 15. December 2022
Answer:
Nur wenn das Fenster Richtung Norden verbaut ist oder kaum Sonnenlicht auf das Fenster scheint können Sie auf Ihrem Dachfenster eine Isolierfolie vollflächig von innen anbringen. Wir empfehlen die Isolierfolie, leicht getönt durchsichtig, Art. Nr. 171010. Sie hat den besten Kälteschutz und bietet dazu einen hohen Lichtdurchlass.
