Between the destructive forces of nature and the destructive forces of man, there is a current focus on security and protection for office buildings, government buildings, schools and private residences.  Windows, quite obviously, are particularly vulnerable to these forces.  Allied Window can provide a variety of glazing and product options to increase the level of protection for the window itself, as well as the people and materials inside the building.


The mere presence of an exterior storm window provides added life to existing sash, the paint finish and historic glass.  All of our exterior models can provide this important protection.

GLASS PROTECTION (Especially stained or leaded glass)

Protection from wind storms or vandalism is typically provided by our Allied One Lite (AOL), the Monumental Allied One Lite (MAOL), or even a fixed D-42 or D-48 panel.  A variety of venting options are available for stained or leaded glass, to prevent a damaging heat build-up between the storm and prime windows. Typical glazing options up to (1/4”) are:

  • Tempered glass
  • Laminated glass
  • Polycarbonate (Lexan) –Never use for stained or leaded glass

There is an increasing focus on the need to protect building occupants from the danger of flying glass and other debris caused by windstorms, earthquakes, terrorist acts, vandalism and accidents. Our Monumental Allied One Lite (MAOL) has been designed to provide superior performance in the face if these unfortunate events. A simple D-48 fixed panel can also address this need. Typical glazing options up to (1/4”) are:

  • Tempered glass
  • Laminated glass
  • Polycarbonate (Lexan)
