How security window film keeps you safe

Applying window security film is a popular home improvement method that provides additional security to your windows and glass doors by reinforcing the glass. The process makes your windows completely shatter-proof and extremely hard to break through. To a lot of first timers, seeing a security film deflect bullets might seem like magic. It’s not magic, it’s science. Here’s how it does what it does.

It all starts with the production process of the window film. A special type of adhesive is used to bond together multiple sheets of polyester to create a thick film. The amount of polyester sheets that are used for the lamination would depend on the required thickness of the film which in turn would depend on the required final use for it. Thicker films like the 3M window security film are used mainly for security purposes and can be as thick as 14 mil or more. Thinner security window films use lesser layers of polyester and can range from anywhere between 4 mil and 13 mil. They are mainly used for cosmetic purposes or when a lesser amount of security is required.

The second step of providing fool proof security is the installation of the security film. Installation should always be carried out by professional of the industry as novice hands would have the risk of air pockets or bubbles being left during the process. There are a number of installation methods that would vary depending on the functional requirements of the process.

The ‘daylight’ method is the most basic method where normally thinner film which is being used for cosmetic purposes is applied directly on to the glass with small gaps left between the film and the window frame. This is less durable than the other installation methods and is normally used in low risk areas where the main end results required are mainly cosmetic. The glass will still remain shatterproof and harder to break than glass without a product like the 3M window film. 

The other type of installation method is called the ‘anchored’ method and is used when the security requirement of the fitting is higher. There are two variations of the method that are called the wet and mechanical installation methods.

In the wet method a smaller gap is left between the film and the window or door frame when applying the film. This gap is then filled with a strong special adhesive that bonds the film to the frame and hardens the glass in the gap.

No gap is left between the film and the frame in the mechanical method. The film is actually overlapped on to the frame and then it is fixed to the frame mechanically using either metal batten strips or other methods.

The reason window security film provides such an elevated level of security is because the painstaking production process and multiple installation methods have been developed to ensure the maximum security for your glass.

    I wasn’t very confident in what a 3M window film can do and then I watched a youtube video. Boy, was I wrong! I couldn’t believe how difficult it is to actually break the window once this film is attached! It’s pretty amazing!
