Can you apply window film over stickers
Commercial windows and doors, especially on storefronts, usually have security tapes, stickers, decals and other information on the glass. In most cases these signs and decals must be removed from the glass before the window film application. They are removed because the window film over the decal gives a raised appearance to the film.
Your window film specialist can recommend what to do based on the material, thickness and situation. Usually super flat decals are not removed and window film could still be applied over them. However, the appearance will have a slightly raised look and the decal will not be able to be removed until the window film is removed. You can consider reapplying the stickers on the other side of the glass (image reversal). Highly raised decals or stickers should be scraped off.
Safety and Security Film
Attachment security systems and alarm contacts are usually found on commercial glass windows and doors. The attachment systems are usually raised above the surface over the edges of the glass pane. Solar control window film can still be applied on these windows/doors. If alarm contact is also found on the windows, it should be removed before the window film application. Your window film professionals shouldn’t remove alarm contact, it needs to be removed by your security company and replaced after window film installation.
Safety Windows Films are a more affordable and easy way to bringing your building up to code by adding safety film over existing windows to get a Tempered Glass rating. As proven by impact-tests, they increase safety and protection for building occupants and visitors.
Sticker Certification
When you add a security system installation to create a Tempered Glass rating you may need the proper certification to show the window meets code. In this case, do not to put the window film over stickers, but instead, put the sticker over the film as you won’t see the slightly raised film in the area of the sticker.
Can you layer window film
In some cases you desire two layers of window film. This happens when you already have a solar control film but want to add safety and security film. It is possible to add the second layer of window film. We also see this when you are using a couple different decorative films to achieve a desired look, again this is possible.
