Wrap your room in natural light. Introducing a 90-degree corner window designed with clean, straight lines to maximize your view. Whether you want to finish off a sunroom with architectural interest or create expansive panoramic views in a kitchen, our corner windows are built to give your project a bold, modern look.
Our Pinnacle clad 90-degree corner window is constructed with a low profile direct set frame, allowing for architecturally correct alignment and sightlines with other Pinnacle clad low profile direct set and radius products. Increased visible glass provides a clear view of the outside world, while high-performance thermal ratings maintain a comfortable indoor environment.

- Choose from standard or contemporary stops
- Frame incorporates a ¾” wood frame and clad frame height of 1-1/2”
- Vinyl drip cap and vinyl nail fin are standard on all corner windows; rigid drip cap and rigid nail fins are optional
- Frame corners are keyed, screwed and silicone injected
- Corner post connection to the main frame is also screwed and silicone injected
- Position of the glass is in the same plane as the Pinnacle clad casement glass
- A deeper exterior glazing leg allows for the use of the tall putty and contemporary WDL bar
- Corner units are available with a glazed corner post or choose to forgo the post altogether for virtually unobstructed sightlines (Open units with no corner post will require field glazing by others)
