From the outside of the Home, start first with a width measurement. We are looking for the opening size, not the window size. Measure from one side to the other, from edge of opening to the opposite edge of opening. Make a note of this size.

Do the same for the height of your opening. Measure from the top edge of the opening to the bottom edge of the opening – this is your height (or length).

Now you can refer to these measurements as width x height.

Example – 54” x 74”

We typically recommend a 3” overlap beyond each side of the opening, which would result in adding 6” to the opening width. Having a 1” or 2” overlap on each side may result due to panel widths and or wall limitations – this is OK.

The same applies for the panel height – we typically recommend a 3” overlap above and below the opening, which would result in adding 6” to the opening height. It is important that this amount of space is maintained (edge distance) to insure that the anchors at the top and bottom are properly secured into the structural substrate (wood, CBS, or concrete)

Example – opening size of 54” x 74” = coverage size of 60” x 80”

Keep track of your measurements on our Measuring Worksheet

See Available Tracks. See Available Hardware.

You can refer to our Width Chart and Height Chart to determine what you need to get the proper coverage. Also, you can refer to our Coverage Chart to verify that you have enough panels (12” of width coverage per panel) to overlap both sides of your opening.

If you have a bottom sill / ledge that projects outward, instead of building out the entire system to create clearance for this projection, you can run the panels sideways or Horizontal (see depiction above).

Basically take the same approach as above, knowing that after you add the 3” beyond each side (for a total of 6”), your panel length will be your width measurement plus 6 “.

Remember that your bottom panel will rest on top of the projected sill and you will continue with your coverage upwards until you reach an overlap at the top.

Example – 54” x 74” Your panel length becomes 60” for this horizontal application.

Now the question becomes – How many panels will it take going up vertically to cover your length?

You may encounter a window where the glass goes to the ceiling or eve.

Here, you can go horizontal again, with your first panel resting against the top eve with your coverage continuing downward until an overlap is achieved at the bottom.

Also, you may encounter a Sliding or French door that has no wall space underneath as the opening goes all the way to the floor. In this case, you can use a removable floor track or you can run the panels horizontal. It is very important that you look for any obstructions on all 4 sides of the opening and figure out the appropriate solution to each circumstance.
