Hopper Windows

Tri-State windows represent a dramatic development in materials and design. You can benefi t the most by owning the Hopper Window and all of its exceptional features. Fully welded Main-Frame, fully welded sashes, advanced weatherstripping and double locking system, all of which keep out moisture and drafts.

The Hopper Window All-Welded construction creates a one piece sash and frame that is permanently sealed against the elements. The Optimum triple glazed and dual sealed, composite warm edge super spacer between the argon filled panes of glass eliminates any chance of moisture between the glass. Our superspacer is made from a space age silicone composite, originally used on the space shuttle. Both beauty and efficiency make this window the right choice.
