This video will show you how to measure your window for our product

Choose the Mounting Style

Our clear insulation panels mount on the INDOOR side of your existing windows.

There are two ways to do this:

• Front Surface mount
  
• Recessed inside the jambs.

The Choice Is Yours

Choose whichever mounting method is best for your windows. You may choose to mount some windows with one method and some with the other. We’ve shown double-hung windows here, but the same principles apply to casements, sliders, tilting, and picture windows. Blinds or curtains may need to be relocated slightly for clearance.

Once you’ve chosen a mounting method, proceed to step two (measuring) page to see how to calculate the sizes you’ll need.

• Mounts to front surface of the trim molding surrounding your window.
• Is LARGER than the window opening, usually by ¾” on each edge (1-1/2″ overall)
• Requires a relatively smooth area of at least ¾” on the trim molding along the sides and top of your window.
• If you have a protruding window sill, the bottom of the Advanced Energy Panel will rest on that.
• Held in place with twist clips.

Thumb Twist Levers
Six twist clips (on average) hold the panel tightly against the front molding. (Note that you have a choice of brown or white panel frames and clips.)

• Mounts recessed inside the window opening on stops which are attached to the sides (jambs) of the window frame.
• Is SMALLER than the window opening, usually by 1/8″ on each edge (1/4″ overall)
• Requires at least a 1-1/8″ depth of recess from the front surface of the jamb to the window stop
• If you have a protruding window sill, the bottom of the Energy Panel will rest on that.
• Held in place with jamb clips.

Jamb Clips
Six jamb clips (on average) are screwed to the side jambs; they hold the panel securely against the window stops. (Note that you have a choice of brown or white panel frames and clips.)

Window Stops
If you choose the recessed style of mounting, you will need window stops. These may already exist; they are usually next to the moving sashes, along the sides and top of your windows.  Boomerang Energy Panels rests against the stops.  If you don’t have any, call us and we will discuss the best way for you to add them.  It is important they are tightly sealed with caulk.

Here’s a close-up view in the lower right hand corner of a window. The stop is a piece of wood, usually about ½” thick.

The stop keeps the moving window sash in place and serves as a solid object against which to put the  Energy Panel if you choose the RECESSED style of mounting.
In the photo, the top of a white Boomerang Energy Panel is being positioned against the window stop. Jamb clips will hold it flat against the stop when in place.
