MI Windows and Doors, part of the MITER Brands portfolio, has launched the VX4500 and AX4500 Moving Glass Walls, large-format pocket and stacking systems that span up to 20 feet.
The walls come in 2-, 3-, and 4-panel configurations. The VX4500 uses a metal-reinforced premium vinyl frame in white, almond, clay, and Carbonite black, with color-matched handles. The AX4500 pairs an aluminum frame in white, clay, bronze anodized, or satin anodized with black, brushed nickel, or clay hardware.
Four insulated glass options are available, including UV-resistant Low-E coatings. A narrow frame maximizes views, and the panels float over their track for smooth operation across a variety of flooring types. Energy-efficient construction and integrated water management protect the home in every season.
An ergonomic SmartTouch handle engages a multi-point locking mechanism and bolt with a single swipe. A concealed multi-point lock adds strength to the large sliding panels, and a keyed cylinder is optional. Both lines carry a lifetime limited warranty.
“This launch demonstrates MI Windows and Doors’ commitment to blurring the boundaries between indoors and out, opening new possibilities for spaces,” said Kenyon Browning, Sr. Sales Representative at MI. “Beauty is truly built to last with these products, allowing homeowners to enjoy natural light and seamless living spaces with premium components, thoughtful engineering, and an industry-leading lifetime limited warranty.”
