Window Saver Kits

Window Savers consist of sheets of Plexiglas (or other acrylic brand) held magnetically on the room side of your primary window to seal out drafts, stop condensation, build an insulating air space, and cut street noise. Comfort gains and energy savings are large. On a completed Window Saver, rubber strip magnets (your refrigerator door uses these) are mounted at the edges of the Plexiglas and cling to vinyl-covered steel strips surrounding the window. The steel can be mounted to the molding (the "picture frame" around the opening) or to cleats tacked inside your jambs (see diagram at right). 

​

Kits contain 100' coils of material (photo below) for building windows of any size. One kit will make seven average-sized (3'x4') windows. Kits do not include the acrylic sheet.  You buy that (usually in 1/8" thickness) cut to size from your local home center or plastics distributor. (See Plexiglas for guidance on measuring and buying acrylic sheet.)

​

Window Savers take less than 40 minutes to assemble, and can be changed in or out seasonally in mere seconds. All components are adapted for sun tolerance. All adhesives are pressure-sensitive and acrylic-based for strength and long life.

​

Assembly is simple once your mounting location is selected and your cut-to-size acrylic sheet is in hand. No mitered corners are used.

 

Choosing a Mounting Method

Window Savers mount to the casings or to cleats tacked inside the jamb.  See illustrations at right.

​

Wall or molding mounts are easier and usually not visible, because they hide behind your curtains.  However, not all casings have a flat or a broad crown in their profiles, and some casings have raised corner blocks.  In these situations a jamb mount is preferred.

​

Jamb mounts need 3/4" square pine sticks for “cleats.”  Tack them to the jamb around the window, 1" to 5" from the glass.  If a window sill intrudes, the bottom cleat (and its steel-and magnet) can be omitted, and a foam weatherstrip which cups the bottom edge of the Plexiglas, substituted.
