Mounting & Plexiglas

Choosing A Mounting Method

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

Casing 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 weather strip which cups the bottom edge of the Plexiglas, substituted. See diagram on Window Saver Kits page.

Mounting Options

Measuring for Plexiglas

Measuring methods are the same for both types of mounts.

Make your Plexiglas 1-1/8" greater than the distance between opposite inner edges of the 5/8" steel mounting strips. If weather strip is to replace the lower cleat, measure down to the sill and add 1/2".

Buying Plexiglas

Plexiglas is one brand of acrylic sheet, but almost any brand will do. Acrylic no longer yellows. First, make a list of the sizes and quantities you need. Measure to the nearest 1/8". The thickness you want is also 1/8". Exceptions: acoustical windows. See that page. For patio doors, use 3/16" if you can get it. It stays flatter than 1/8" and is easier to handle.

Home Centers and plastics distributors both have good prices, but distributors have the best selection and cutting equipment. You will find them listed in the Yellow Pages under “Plastics — Sheet, Rod and Tube” or similar listing. Both paper and film-protected types of acrylic are fine, but the latter is less expensive. Prices for it will range around $1.50 per square foot, cut to size. Don’t pay more without shopping your area thoroughly. The usual practice is to give the supplier your credit card number and cutting list by telephone, fax or mail, and then sign when you pick up the cut-to-size pieces.

Lexan polycarbonate also works and is tougher than acrylic, but it scratches more easily, and costs twice as much. It is not usually needed unless you live beside a golf course or fear vandalism.
