The profile of a plastic window is covered with a special film that protects it from dirt, scratches and other mechanical damage during delivery and installation. It is very easy to remove it from the product, but it must be done in time. It is advisable to start this immediately after the window is installed. Otherwise, it will be necessary to resort to more radical methods of cleaning the film from the profile.

Why is it difficult to remove protective film from a window?

The instructions for plastic windows usually indicate that the film must be removed within 2 weeks after installation. Removing the film will not cause much difficulty in the coming months. However, if it remains on the profile for more than 4 months, a lot of effort will have to be made to remove the film.

For what reasons could this problem occur? The film contains several layers that are attached to the profile using special glue. Strong bonding with plastic occurs under the influence of solar radiation, as well as heat. In other words, the process of decomposition of the inner very thin layer of the film occurs. Therefore, the inner layer is much more difficult to remove than the surface layer.

Reasons that contribute to increased adhesion of film and PVC frame:

action of heat. In summer, the film dries to the frame much faster than in winter;
The quality of the special glue applied to the film affects the difficulty of its removal. The cheaper the windows, the lower the quality of the glue;
exposure to UV rays. The adhesive layer of film on windows located on the south side of the building may dry out faster. Therefore, it can be more difficult to remove film on such windows than on windows located on the north side.

How to remove film and adhesive tape from metal-plastic windows

It is recommended to remove the protective film from the window within 2 weeks after installation. Then it will be difficult to do this.

You may need to seek help from a cleaning company or wipe off the old tape yourself using tools and substances such as:

scraper;
construction hair dryer;
scissors;
Cosmofen;
different chemicals.

If the adhesive tape does not come off completely, you should use alcohol or tape.

Methods for removing adhesive tape from plastic windows

There are many methods for removing adhesive tape from double glazed windows. However, the fastest and most in effective ways, thanks to which all the film is removed and the surface of the window is not damaged, are the following:

scraper or brush. Removing tape with this tool will never damage the window surface when used with a soap solution;
an eraser that will need to scrub the film quite intensively. But at the same time, the profile surface is well preserved;
construction hair dryer - the best remedy, but when using it, one condition must be observed. The hair dryer can only be directed at the frame. If a stream of hot air hits a glass unit, it may crack or burst due to exposure to temperature. A construction hair dryer heats the tape, after which the glue begins to dissolve, which means you can easily remove it;

Advice. If you don’t have a hair dryer, you can always use a regular one, but it should work in turbo mode. But do not forget that this option is suitable if the protective film is not very strongly glued to the PVC profile.

White spirit can also be useful in removing the adhesive film from the product, but it is usually applied not on top of the PVC window, but between the film and the surface of the product. It is necessary to pry up its edge and moisten the area with white spirit. Wait a few minutes and remove the film;
Cosmofen is excellent at removing film. This product has proven itself as a cleaner for plastic windows;
thin knife. You should use such a tool carefully, since pressing it hard can scratch the window profile. In this case, the actions should be as follows: use a knife to pick up a small edge of the film, then tear it off very slowly. Residues of glue are removed using a solvent;
Wide tape will help remove any remaining adhesive tape. It's very easy to use. You need to stick the tape on the surface and carefully remove it along with the rest of the film;
Industrial alcohol or denatured alcohol must be poured into a small spray bottle and the substance should be sprayed evenly onto the protective film. The denatured alcohol should be left on the surface for a few minutes. Then pry the edge of the film with a knife and remove the film. In this way, the entire profile is sprayed and the remaining film is removed. The glue is removed acrylic solvent;
Schumann. The effectiveness of this detergent, which is produced in Israel by the Buggy company, has been proven by numerous consumer reviews. And since this strong remedy, then it must be used with extreme caution;
RP-6 - excellent remedy to remove the film, which must be applied thickly to the surface of the frame for 10 minutes. The film swells and comes off easily after using this drug;
a weak solvent does a good job of removing traces of PVC films. However, remember that before you apply the product over the entire surface, you need to test its effect on an inconspicuous area of the window.

Attention! It is worth saying that the options listed above are always applicable for all parts window designs, since the adhesive used for them is the same.

Before using the steamer, you need to find the edge of the film on the window and start working from there. The steamer is directed to the indicated place, and it must be kept at a distance of 5 cm from the window. Usually within a minute, and sometimes even earlier, the film begins to peel away from the glass. As soon as the corner comes loose, grab it and carefully pull it towards you.

When working with these products, you only need to wear gloves; do not forget about eye and breathing protection. Products that are used to clean glass-ceramic surfaces help a lot. Take a close look at the detergents you have at home: if they are designed to remove dirt from glass-ceramic surfaces, then you can easily clean glass with them.

Since the sun protection film used for windows contains aluminum, it is necessary to select products that will help get rid of this particular substance. If, with the help household chemicals the film is not removed, then you can always turn to a proven mechanical method and do all the work using a blade or other sharp object.
