Purchasing Materials

All of the material used in this system can be purchased at your local home store. The shrink material kits are usually found in the window screen repair section and window/door sealing and insulation area. When I purchase the shrink film, I try to buy a box with one large piece of film material, such as a kit used for sliding patio doors. This is usually the best buy for the money, although you will have to cut the film to fit the approximate size of your window.

Notice that the top box in the picture at left includes one piece of shrink film, while the bottom box has 5 pieces. If you like you can purchase the individual sizes as shown in the bottom box, either will work, but the larger size gives more flexibility in installation on odd sized windows

The shrink material kit available in your area may be packed differently or made by a different manufacture. This material is usually less than ten dollars and will seal several windows

The aluminum screen repair extrusion can be found in the window screen repair section. This material is supplied in usually three colors: Brown, White and Natural Aluminum. I try to buy the color that matches the window frame or the window jamb color. You will also need some small flat headed nails or brads and a tube of clear caulk, along with the window repair retainer spline. The spline comes in several sizes measured in thousandths of an inch. The spline needs to be a fairly tight fit in the extrusion spline groove. Usually a spline size of about  0.130 is about right. You may have to purchase several sizes to get the size that will be easy to install, yet hold the film tight enough to withstand the air pressure against the film
