Exterior / Inside Removable Storm Windows

These exterior windows excel in situations where panels need to be moveable or operable from the interior for ventilation, egress, or cleaning. Used typically for wood windows, they provide sash protection, as well as added security.

The Historic One Lite (HOL) series is designed to be “invisible”, - when painted the same color as the existing sash. Existing sash should be operable, to permit removal and/or cleaning from the interior. There is no hardware on the exterior. Typically, one or two panels are removable from the interior, and are secured by perimeter clips.

The Allied One Lite (AOL) series is used where the top sash of a double-hung is not operable, but the bottom panel needs to be inside-removable. The upper panel is outside-removable, and “invisible clips” (flush) are available for the perimeter.
