For a bolder/stronger frame that will accept heavier glass, including insulating glass, go to the Magnum™ Double-hung window section.

For clear unobstructed vision go to the ClearVENT™ sashless doublehung section.

Weatherproof: Features such as double sealed top rails with built in drainage troughs ensure maximum water resistance. There is also a special high specification sill option for very exposed locations.
