Installation Methods

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

Most common for Safety & Security films.

Daylight Installation is the most commonly used installation method for Safety & Security films. After applying the final pattern to the glass, the key step is make an additional cut around the entire sheet of film in order to leave a 1/32 to 1/16 inch space gap between the edge of the film and the framing system. A good tip is to use the gasket to help guide the Olfa knife blade as the cut is being made. 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. This prevents water from seeping under the gasket, which can flush out dirt and ruin an installation.

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 – Wet Glaze & Mechanical
Anchored Installation methods are used when trying to optimize glass hazard mitigation. They are more labor intensive versus Daylight or Edge-to-Edge installation, but cost considerably less compared to laminated glass. There are 2 types of Anchored Installations – Wet Glaze & Mechanical:

1. For Wet Glaze installations, the film is installed using the Daylight installation method. After the film is applied and all of the water is squeegeed out, the 1/32 to 1/16 inch space gap between the edge of the film and the framing system is then sealed using a special silicone structural sealant (JWF recommends Dow Corning 995). A caulking gun is needed to place a 1” bead around the edge of the film and frame (make sure the sealant covers 3/16” on both the film and frame ). It requires many hours of practice to perfect this technique cleanly. Applying this sealant on all four sides helps lock the film in place to the glass and framing system.

Apply silicone liberally. Keep it looking clean.

2. The Mechanical installation technique is used to allow the film to be attached 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.
