The Original Design: The original windows were either 5/64″ (.080″) or 1/8″ (.125″) thick. Some aircraft were also equipped with double pane windows, the inner pane being .040″ or .060″ thick.The LP Aero Plastics, Inc. Mod: This STC allows 1/8″ (.125), 3/16″ (.187″), or 1/4″ (.250″) side windows to be installed in all models. The thicker windows are more rigid and therefore resonate less, transmitting less noise into the cabin. They install exactly as do the original windows with the extra thickness being accommodated by moving the retainer angles and screws inward (see figure 1). If double pane windows were originally installed, the STC thicker windows will eliminate the inner panes, and relocation of the retainer angles may not be necessary.Competitive Information: No other company offers STC Extra-Thick Side Windows for these aircraft.Options Available: Thicknesses of 1/8″, 3/16″, and 1/4″ are available, along with Clear, Green, or Solar Gray Tints.
