The WindowShield sun protection film made a good impression in our test. In addition to the high-quality visual impression, the product impresses with its functional design. The material is well processed and has no unclean edges or creases. Only the rolled delivery makes handling more difficult , but at the same time proves to be useful for safe transportation. The equipment supplied and the self-adhesive backing make it easy to attach. Fitting alone requires a little patience, which is why we recommend a second helping hand. The sun protection film promises heat insulation in summer, heat retention in winter, privacy protection during the day and protection from UV radiation. If the customer is not satisfied with the product, they can contact the German family business at any time to solve the problem.

Packaging
The WindowShield sun protection film arrived for our test in the typical Amazon shipping box. This was undamaged on arrival and could be easily opened by removing the adhesive strip. The product box contained the rolled-up film in a round, sturdy cardboard shipping tube. This packaging method provides the product with optimum protection against external influences. As a result, product protection was fully guaranteed and the sun protection film was delivered in perfect condition .
The packaging is partially recyclable. However, the cap cannot be recycled. Notwithstanding this, the presentation of the product makes a very good impression.
After unpacking
Package contents and instructions
ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the package complete and does the manufacturer make it as easy as possible for me to use the product straight away?

Close-up
First of all, it should be mentioned that the sun protection film makes a very good visual impression. We did not notice any processing errors, unclean edges or creases. The product also impresses with its functional design. The tools included are also of high quality. Only the rolled delivery makes handling more difficult, as the material initially wants to retain its original state during installation. The problem is solved on first contact with the window.
There is no information on the sustainability of the product. The manufacturer merely points out that the sun protection film can be easily removed if necessary. Due to the high-quality materials and excellent workmanship, we assume that the product will have a long service life. In addition, customers can contact the German family business at any time if they have any queries.
This is what our practical test showed
Does the manufacturer keep its advertising promises?
ℹ️ Our practical test is the most relevant and therefore the most important. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.
| Criterion | Remark | Score achieved* |
|---|---|---|
| Assembly | Possible alone, recommended for two | 80 points |
| Liability | Very good adhesion, self-adhesive | 90 points |
| Functionality | Multifunctional: heat control, reduced light irradiation, UV protection, privacy protection during the day | 100 points |
| Variants | Various sizes | 90 points |
| Total | 90 points |
*The maximum score is 100 points
The WindowShield sun protection film generally surprised us in a positive way. The equipment supplied, especially the high-quality squeegee with felt layer, was very useful and theclear installation instructions helped us to apply the film to the window. In contrast to the manufacturer’s other window films, there were no markings to cut the film precisely to size, which is why we used a ruler to help us. The self-adhesive backing in combination with plenty of lye water adhered very well to the window at the first attempt. Any air bubbles could then be smoothed out with the squeegee. Nevertheless, it should be mentioned that mounting alone requires some patience and is much easier with two people. Especially as this avoids the possibility of the back sticking.
Overall, the sun protection film offers good privacy protection during the day thanks to the reflective coating, without noticeably darkening the room. In our test, we also noticed that our bay window heated up considerably less. How the UV and heat protection behaves in summer would have to be determined in a long-term test.
The tested model in the size 44.5 x 200 cm is also available in 60, 90, 119, 149 x 200 cm and 44.5, 60, 90 x 400 cm.
Price/performance ratio
and ratings from consumers
ℹ️ Finally, we look at how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also examine consumer ratings and check whether the critical and positive reviews are actually justified.
| Criterion | Remark | Score achieved* |
|---|---|---|
| Price / performance ratio | Good | 85 points |
| Rating cut | 4.2 out of 5.0 on Amazon | 60 points |
| Total | 73 points |
*The maximum score is 100 points
On the Amazon platform, consumers have given the product an average rating of 4.2 stars. Some complain that the sun protection film evaporates very much and that the cooling effect is just one degree. In contrast, other reviewers praise the heat protection and the high quality. Almost all reviews recommend installation with a lot of patience and a helping hand. In our practical test, we can confirm that a second person is recommended during installation. We also noticed a heat-protective effect. In order to be able to make a more precise statement here, a practical test over a longer period of time would be necessary.
Prices of up to €25 are charged on the internet for equivalent products. Very inexpensive products, on the other hand, are available for as little as €10. The WindowShield sun protection film is therefore in the middle price segment with a current price of €19.95. Consequently, the price ratio is good for the quality and scope of services you receive.
