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, in a blast 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, and be sure to ask for the testing data. Recommended installations, and test information should always be provided by the manufacturer, and this information is readily available.
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! With that said, the attachment system will not work with all window frames, it’s important that the frames of your glass can accommodate at a minimum 3/8 to 1/2 inch bead of silicone attachment to the film and frame of the glazing system in order to achieve optimal results.
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 assist you with more time to respond.
Also, the attachment system simply won’t work on some window frames. Recommended silicone attachment is between a 3/8-1/2 inch thick bead, ideally being 1/2 inch. Some frames just can’t support this, allowing the Security Film System to give you some additional benefit, but not optimal performance. It’s important to consult with professional window film company to ensure your window frames are suitable for a Security Film System.
The most FAQ window film dealers get is: Is it bullet proof?
The answer is no. Our 3M Security Window Films are not bullet proof.
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 $12-$20 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 and site visit should be required for Security Window Film installations as they aren’t all the same. The application and type of security window film will be determined by your windows and frames. The Attachment System simply 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, and more importantly, not effective. 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.
