Home Security Window Film
Windows and glass can be seen as a potential weak link when it comes to security, but an application of specialist window film can provide an effective barrier, delivering increased security. Safety and security window films are polyester, or PET films that are applied to glass and glazing in order to hold them together if the glass is shattered. Unlike laminated glass, these shatter safe films can be applied to the glass or glazing after manufacture or installation, i.e., as a retrofit.
Available in a range of thicknesses from standard safety film to bomb-blast protection, security film will allow the glass to withstand an amount of impact, serving to slow down and deter intruders, whilst also providing protection against accidental damage.
In the event of breakage, the security film will hold the broken glass together and in the frame, making it hard for potential intruders to obtain unauthorized access to your premises. Since the glass breaks safely, the security film also prevents broken glass falling inwards and injuring those inside. Moreover, security film obscures vision through glazing; valuable equipment or possessions can be hidden from view, ensuring they don’t become a target for opportunistic criminals.
Security Film Installation
There are 3 basic Safety & Security film installation techniques used by today’s dealers. The decision on which one to choose depends on the type of framing system as well as the level of protection needed. The 3 installation techniques are
- Daylight Installation: Daylight installation is the most common installation method for Safety & Security films. After applying the final pattern to the glass, an additional cut is made around the entire sheet of film leaving a narrow gap between the edge of the film and the framing system. The Daylight Installation method will not only hold glass intact during smaller impact occurrences, but the gap makes it easier to squeegee out water from underneath the film.
- Edge-to-Edge Installation: The edge-to-edge installation technique is used when working with new glass that has yet to be installed into a framing system. Safety or Security film can be applied to 100% of the glass surface because the installer no longer needs to worry about having a daylight gap to help squeegee out the water.
- Anchored Installations: Anchored installation is used when optimizing glass hazard mitigation. They are more labor intensive versus the previous installations. There are 2 types of anchored installations – Wet Glaze & Mechanical:
- For wet glaze installations, the film is installed using the Daylight installation method. After the film is applied and all the water is squeegeed out, the narrow gap between the edge of the film and the framing system is sealed using a special silicone structural sealant. Applying this sealant on all four sides helps lock the film in place.
- The Mechanical installation technique is used to attach the film to a special bar and batten mechanical attachment system. Installers need to cut the film so it not only covers all of the glass, but the framing system as well. The film is applied to the glass and then attached to the framing system – either from the top of the frame, on the two sides, at the top and bottom, or on all four sides.
