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. Units are trimmed with Mylar foam tape which eliminates the need for caulking, and provides easy removal for painting.

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 Operable Historic One Lite (HOL-OP) series has the same "invisible" appearance as the (HOL) units, but the bottom sash is operable and removable. It also has a year-round screen.
