Getting Started
The first thing that you should do is measure the windows that you intend to secure with window security film.
Please Note: Window security film is measured and installed on the inside surface of the window, it is not applied to the outside.
What you will need before you get started:
- Measuring tape
- Pencil
- Paper or a notebook
- Calculator
- This measuring guide
Measuring your windows
- Using a sheet of paper, do a rough sketch of the window layout as shown
in the example diagram of step 4.
- Measure each pane of glass (only the glass area, do not include the window
frame) and write the measurement in inches next to the top, side or bottom
of the pane that was measured.
- Label each pane of glass on your diagram with a letter of the alphabet;
this will help you work out how much film you need to purchase. Keep a copy
of the diagram, as it will be helpful when installing the film.
- Window Pane Sketch:
- The next step will require you to overlay each of the sketched window panes
onto a diagram representing a roll of film. This will become your ordering
plan.
- Using another piece of paper draw a long vertical box, this represents
the length of film and label the heading of the box as 60” wide. Using
the measurements taken in step 2 arrange the window panes so as to make the
best use of film width and to minimize film waste.
- Film ordering plan:
- 8. At the bottom of the diagram, add up the sizes of each window in your diagram to come up with the total linear measurement – i.e.
20+20+48 = 88” total length.
- Next convert your total length to number of 12" (1 foot) linear feet units. For this example, we divide the total length by 12" and have the total number of linear feet needed to purchase. i.e. - 88" / 12" = 7.33 linear feet - Since the window security film is sold in full linear foot increments, we will need to purchase 8 linear feet of window security film for our example windows.
- With careful arrangement of the windowpanes (step 4 above) onto the film
ordering plan (step 7 above), you may be able to minimize the amount
of film needed. Any surplus film you have after cutting film can be used to
practice installation on a small window or piece of glass.
- Take your time and work out how much film you really need. When the film
arrives and you are ready to install, carefully follow the installation instructions
and practice with some film off-cuts. Most importantly just take your time.
