Putting screens on and off each season was growing old. Only having screens on in the warm seasons didn't provide protection from the elements. (Rain, pollen, dust, high winds you know if you have a screened in porch)

Hence the birth of the expanseTM window. The best of porch living. Screens without having to look through them. Screens that retract when the weather calls for it. Clear views of your favorite backgrounds, your front or backyard.
