PGT’s WinGuard Vinyl Preferred View Sliding Glass Door now offers door panels with up to 60 square feet of glass in sizes as large as 6’ wide x 10’ tall or 5’ wide x 12’ tall, spanning up to 48 feet in 8-panel configurations.

The Preferred View Sliding Glass Door now offers door panels with up to 60 square feet of glass in sizes as large as 6’ wide x 10’ tall or 5’ wide x 12’ tall. These expanded dimensions are available in a variety of operating configurations depending on panel height. All sizes up to 12’ tall are offered in bypass and pocket configurations, while 90-degree or 135-degree corner configurations are available for doors with panels up to 10’ in height.

“Over the past decade, we’ve seen consistent demand for more glass and less frame,” said Brian Covey, Vice President of Sales, MITER Brands-South. “This latest enhancement gives homeowners the expansive sizes and minimal sightlines they’re looking for. True to its name, the Preferred View Sliding Glass Door delivers wide-open views and natural light like never before.”

Since its launch in 2023, the Preferred View Sliding Glass Door has become a favorite among homeowners and builders for its narrow 2.5” interlocks—half the width of standard designs—and its ability to scale up to 8 panels wide. Now capable of creating openings up to 48 feet wide, the door offers a striking way to maximize views, integrate indoor and outdoor spaces seamlessly, and develop a sense of openness in any room.

Part of PGT’s WinGuard Aluminum impact-resistant door series, the Preferred View Sliding Glass Door features a robust aluminum frame engineered for durability, long-lasting strength, and performance. The door is also equipped with heavy-duty tandem rollers for smooth, fingertip opening. At the same time, a dual-point locking mechanism enhances security by preventing the panels from being lifted off the tracks.

With the addition of larger panel sizes for the Preferred View Sliding Glass Door, PGT continues to push the boundaries of innovation and design, offering homeowners bold new ways to customize their living spaces with the sleek and modern aesthetics they desire.
