Window security film is made up of one or more layers of polyester film that have been laminated together using special adhesives. These layers can adhere to one another in a number of different ways. The thickness of these might range anywhere from 4 mils to 15 mils or even more. In general, a thicker film is more durable and has a lower risk of being broken, torn, or punctured than a film of a thinner thickness. When it comes to tinting or solar protection, thinner films are typically utilized because of the increased attention placed on optical quality. However, there are some producers who use nanotechnology to create thinner films that are even tougher than thicker films, despite the fact that the thinner films cost more. For instance, there are nano-layered films that are eight mils thick that test just as well as normal security films that are fifteen mils thick. These multilayer thin security films are advantageous because they have a higher rip strength than conventional security films. As a result, they are better able to withstand bomb blasts, forced entry, and harsh weather occurrences. When it comes to the topic of security window films, this is an extremely important point of discussion. When using thicker security films, it is common to experience a decrease in the film’s optical quality. The vast majority of the time, this does not matter, but it is something to think about before making a choice.
- Most individuals choose film because it’s inexpensive and doesn’t require window or door replacement.
- Security window film may not work for old or fragile glass.
- The film is fantastic for renters because you don’t spend a lot of money on something you’ll leave behind.
- Average costs range from $7 to $15 per square foot. Installing a security film on a 3′ x 5′ window costs $105 to $225 or more.
- Near-invisible or opaque films offer security and privacy. Some marketers interpret the word “security” to mean privacy. Security equals privacy, therefore, not all “privacy” or “security” films harden glass.
- The UV-blocking film keeps your home cooler and reduces sun damage to furniture, carpeting, etc.
