Window Types

Milgard A250 Radius

A250 Thermally Improved Aluminum radius windows feature soft curves that make them very visually appealing. Try a full round, quarter round, half round or arch top. Combine a radius window with casements, pictures, awnings or single-hungs for endless design possibilities.

Milgard A250 Picture

Because of their clean, narrow sightlines, A250 Thermally Improved Aluminum picture windows make a beautiful wall of windows when used in combinations. These metal windows do not open, or have any rails to obstruct their view, making them ideal for large walls and high ceilings.

Milgard A250 Single Hung

With A250 Thermally Improved Aluminum single-hung windows, the lower panel slides vertically upward when opened and it overlays into the stationary top panel. You can close and lock the window securely, in one motion, with the spring action lock. If the window is closed, it's locked.

Milgard A250 Casement

A250 Thermally Improved Aluminum casement windows are built to your exact specifications. Aluminum casement windows can be easily combined with other casements or operating styles for a dramatic effect. Casement windows open to the exterior of the home with a side hinge, similar to a door.
