Safety and Security Films
Check out the first edition of Installer Perspective,
a new column in which 2012 Architectural Tint-Off™ Competition winner
Hann Kim explains his tips and techniques for various film installations.
To a film installer, safety and security film can be a little
intimidating. You might think, “It’s a little thick, I don’t know if I
can install this,” or “Does the installation of this film require special
training?” As long as you have the desire to learn you can be the best
installer of any film, including these.
Learning the Specs
Understand that safety film is just like any other manufactured film with
pressure-sensitive adhesive, except the film is clear and the thickness
can range from 4- to 18-mil and thicker. Most 4-mil safety film applications
are for impact-resistant glazing and that is normally to satisfy a building
and safety code requirement. Some of the thicker films are designed for
more specific applications such as anti-intrusion, bomb-blast mitigation
and tornado/hurricane safety.
How to Install
Regardless of the specifications of the film, the application is going
to require the same installation quality as conventional films: contaminant-free,
bubble-free installation, 1/8-inch light gaps and little-to-no residual
mounting solution left under the film.
Here are the some helpful tips for safety film installation.
1. Try and minimize the amount of excess film by pre-cutting 1 inch more
than the actual window size.
2. During the installation use either the factory straight edge or a pre-cut
straight edge to line up one side of the film, preferably the top or the
sides of the window.
3. Once the film is in position, anchor the film by making a single squeegee
pass down the center of the film from top to bottom.
4. Once the film is securely anchored, proceed to cut away all three sides
of the film making sure the film is not moving around during the cutting
5. From the center/middle of the glass make a squeegee pass left and right
to create four quadrants.
6. Squeegee out each quadrant working your passes from the middle out
to the corners.
7. Once all four quadrants are completed, repeat steps five and six but
make sure your second passes are slower with firmer pressure. I hope this
helps you better understand safety and security films.
