Security Window Film...What you need to know.

While Security Window Film may seem like a new invention, it's actually been around for a long time, over 40 years! Safety and Security Window Film may not be new, but it has come a long way, and new features like the Attachment System have been recommended to increase its performance.

If you've landed on this BLOG, you're probably a bit interested in the product, and you've probably watched footage of security window film being put to the test on YouTube, and other sites. While these videos do give us a good idea of how Security Window Film performs, they can also be a bit confusing.

Let's start with answering the question, just what it is Security Window Film?

  • Security Window Film is a thick piece of window film ranging from 4 mil - 18 mil's (a mil is a thousandth of an inch) in thickness. Some of these films are developed using a cross woven process of the polyester material (I'm sure that was confusing). Long story short, an 8 mil cross woven film may provide as much protection as a 14 mil security film that isn't cross woven.  Check with the window film manufacturer or a reputable window film dealer to better understand what type of Security Window Film will work best for you.

Regardless of the mil, security film is designed to hold the glass in place should it break. Holding the glass fragments together can reduce injury, as well as deter potential intruders by making the glass more resistant.

Another important component of any Security Window Film system is the addition or lack thereof, of the Attachment System. Any video you've watched online most likely has an Attachment System applied along with the Security Window Film.

So just what is this attachment system?

  • The Attachment System is typically a silicone bead, much like you see on the frame of commercial glass, applied after the installation of the Security Window Film, the Attachment System bonds the Security Window Film to the frame of the glass, giving you the highest level of security. In some instances Security Window Film, and an Attachment System are strong enough to withstand a bomb blast!

So what if you're not concerned with a bomb, why do YOU need to consider the Attachment System? Think of it this way, many times the most trouble free windows for an intruder are typically ones like your sliding glass door, or the front entrance to a store. That is because tempered glass (safety glass) is used on these areas. Tempered glass is designed to shatter into thousands of pieces once broken to prevent large shards of glass from injuring someone. Making these windows pretty easy to break out.

Let's say you put Security Window Film on tempered glass without an Attachment System. The Security Window Film will hold the glass together, leaving the intruder to push the glass out in one piece. You may have just help the intruder not get cut while he’s breaking in. If the attachment were to be added, that film is anchored to the frame, making it very difficult to penetrate.

If you add the Attachment System, does that mean your glass in impenetrable?

  • Well, no. Like most security products, security film is a deterrent. It is not 100% foolproof. However it can turn a couple of seconds to respond, to over a minute, allowing you time to protect yourself, and additional time for authorities to respond to a security alarm, or 911 call.

The most FAQ window film dealers get is: Is it bullet proof?

  • The answer is no. Security window film is not bullet proof, and be leery of anyone that says it is. There are some films that claim to be bullet proof. Maybe they are, just do your research on these products, and make sure they're 3rd party tested. And while most Security Window Films are not bullet proof, they are designed to hold the glass together. This will give you some extra time to respond or find safety should someone shoot at your glass.

Another important question is cost. About how much does a Security Window Film install cost?

  • Price can vary depending on where you live, the brand of security film you are purchasing, and the company you are hiring for your film and installation. A professional Security Window Film installation will probably run you between $10-$15 per square foot installed. The Attachment System will be in addition, and is charged per linear foot. Many times the Attachment System can be as much as the film, this is due to the labor and skill required for the application. Be sure to work with a reputable experienced window film company when purchasing security film, you'll get what you pay for!

A professional estimate is typically required as Security Window Film installations are not all the same. The application and type of security window film will be determined by your windows and frames. The Attachment System won't work in every scenario, and may have a high potential of turning out ugly, think Wood Framed French pane windows, not a good look with the Attachment System. Always work with a credible window film dealer that works alongside a credible window film manufacturer like 3M, to ensure you are having your film applied to the manufacturers recommendations by a Professional Window Film Installer.
