Installation Procedure

Installation is really simple and easy if your are the least bit handy with tools and it takes about 45 minutes to an hour for each average window. There may be special situations that might take longer. I wouldn’t expect to do all the windows in a typical house in one day. Pick a couple of the easier windows to begin working on and save the harder windows as you gain experience.

A small flat area of at least 1-inch wide is necessary all around the window to install the 3/4 inch wide extrusion against the window frame. This installation method looks the best...but, other installation methods are possible...such as, installing the retainer system on the wall at the area indicated by the black arrows.

Building windows are manufactured in many varieties of shapes and designs. It is impossible to cover all window types in this installation guide. Therefore this guide will cover the most common type of window, which is a rectangular window with jambs and a sill. This system works best if installed on the interior window jambs next to the window frame, using small nails and caulk to hold the extrusions to the window jambs and sill.

An alternate method might be hot glue or screws on jambs such as adobe or brick or installing the retainers on the wall around the window if the jambs are not accessible. The nails must anchor in something solid such as wood and not just plaster or drywall. Considerable pressure is put on the retainer extrusion by the film shrinkage and air pressure differential.

The best method is using small nails and caulk and this is the method that will be demonstrated in the installation guide. This picture shows the extrusion and film installed next to the window frame. (Small blue arrow). The extrusion used in this example is white and is barely visible.
