Review: So pretty - I have a closet window that faces out to a main road and this is a perfect solution to my inconvenient problem. I love that it still lets in the light but I can still keep my privacy. It was Super easy to install, and has stayed on very well, I have not had any issues with peeling or coming off in any way. I just moved into this house and so I get to show off my rooms and I have gotten so many compliments on this window.
Review: Easy to install. - This film offers an awesome protection. It prevents the light from coming in at the high brightness that it normally does. It helps keep the room cooler. I used some window cleaner to adhere it to the window. I used a small plastic card to press out the bubbles and it stayed on nicely. The adhesion was great. It looks great on the window also. I trimmed it up with a sharp instrument.

## Features

- Break-In Deterrent for Home and Business：Windows are often the weakest entry point for burglars. This 4mil window security film reinforces glass surfaces, making forced entry significantly more difficult. It helps deter break-ins by increasing the time and effort needed to breach a window — keeping your home or business safer and less of a target.
- Shatter-Resistant Protection：Built with durable 4mil thickness, the security window film adds a powerful layer that helps glass resist shattering from impact. If breakage does occur, it holds the glass fragments together, minimizing the risk of injury and property damage. Ideal for both residential and commercial applications where added safety is essential.
- Wide Range of Applications：From residential homes to commercial buildings, this security film for glass windows is ideal for a variety of settings — including supermarkets, storefronts, sliding doors, display cabinets, jewelry shops, schools, airports, banks, and bathroom glass. It’s also an excellent solution for protecting glass furniture from vandalism, scratches, and graffiti, helping to preserve a clean and polished appearance.
- Easy Installation and Removal：Just peel off the protective layer and apply the adhesive side to a clean glass surface — it's that simple! For best results, use plenty of soapy water and follow the included instructions for a smooth, bubble-free finish. When it’s time to remove, the deluxe smart film peels off easily without leaving residue.
- Complete Installation Kit：Everything you need for a smooth, bubble-free application is included: scrapers for even smoothing, a precision cutter for trimming, and compressed towels for surface cleaning — making installation quick and hassle-free.

## Questions & Answers

**Q: How to install transparent window film?**
A: First, clean the glass surface, then generously spray water on both sides of the glass and the film. Then, peel off the backing paper and apply the film to the glass, removing any air bubbles with a squeegee.

**Q: What tools are needed to install transparent window film?**
A: For example, a scraper to remove air bubbles, a craft knife for precise cutting, a ruler for exact measurements, and a clean cloth to wipe the surface (some of these tools must be prepared by you).

**Q: The transparent window film doesn't adhere well to the windows. Do you have any recommendations?**
A: If the privacy window film doesn't adhere well to the window, be sure to carefully remove any dust or residue from the surface. Adding a little soapy water may make installation easier.

**Q: Why does the edge of window film curl? How do I deal with warped window film?**
A: The cause is insufficient adhesion or improper installation. Reapply the film to remove any air bubbles. Or use a hair dryer to heat the curled area to ensure it adheres firmly.

**Q: Why isn't the film sticking properly and is it falling off?**
A: The transparent protective film hasn't been removed. Remove it for proper adhesion. If you removed the protective side, you may have applied the wrong side. Apply the smooth side to the window.

### ⭐⭐⭐⭐⭐ Static Film Perfect
*by F***M on February 13, 2024*

We have been using static film for window and door treatment for years. This brand is perfect in weight and design. After years of using a few of my tips might help those who have never used this type of product: There IS a clear film attached even if you can’t see it. It must be removed. First measure the window, then cut, THEN flick one corner of your cut piece back and forth (in good light) and in a few minutes the clear backing will begin to lift from the corner. Then you can peel it. I clean and dry the surface glass with an alcohol/water spray. I mist spray the window lightly and do a few mists of water on the vinyl itself front and backside. Don’t overdo the water. Start at the top of the window and begin to place it and smooth it. I use a shower type rubber squeegee and a soft towel. Pay attention to the edges. If the vinyl does not meet the glass the vinyl will NOT lay smooth. Bubbles appear when the water has no where to go and stays under the vinyl. Use the razor edge to make certain the vinyl is exact in cut and is in contact with the window. I leave a hair’s length of space between the vinyl and the edge of the window so the water gets sqeezed out easily. I hope this helps. It is a good product. For total privacy use the frosted type and it will look like glass. I even have used the mirror type on a cabinet so it looked like a mirrored door. Endless possibilities.
