MI Windows and Doors Launches New Carbonite Collection

HARRISBURG, Pa.--(BUSINESS WIRE)--MI Windows and Doors, one of the nation’s largest suppliers of precision-built and energy-efficient windows and doors and part of the MITER Brands portfolio, recently announced the launch of the Carbonite Collection, a new premium black/black vinyl window and door collection designed to elevate both traditional and modern residential projects. As part of the launch of the Carbonite Collection, MI is also expanding its portfolio of premium products. Coming Summer 2026, the collection launches with MI’s popular 1620 single-hung and picture windows, 1630 horizontal slider, fixed windows, and three new products: the 3075 Casement and 3065 Awning in its V3000 Series and the VX4500 Moving Glass Wall system.

“The Carbonite Collection represents an important step forward for the MI brand as we continue to expand our offerings with more innovative products and color technologies,” said Robert Jumper, Product Manager at MI Windows and Doors. “The Carbonite Collection is designed to meet builders’ demand for black window and door solutions that combine modern aesthetics with long-term durability and strong performance across a wide range of operating styles and configurations.”

Products within the Carbonite Collection feature premium capstock color technology, the industry-preferred solution for dark-colored vinyl windows and doors. Capstock provides the durability of through-color vinyl, improved heat resistance over standard uPVC vinyl, while maintaining the excellent thermal and structural performance associated with vinyl products.

The new V3000TX casement and awning platforms introduce a thinner frame profile with more glass area than other products on the market, delivering a modern design aesthetic. Designed for expansive openings and indoor-outdoor living spaces, the VX4500 offers highly configurable layouts, including multi-track, pocket, and corner configurations that support large unobstructed openings.

The new VX4500 Moving Glass Wall system further elevates the MI portfolio by offering larger sizes and a capstock solution for modern home designs with expansive, unobstructed openings. Its inclusion in the collection provides consumers with a complete black/black capstock portfolio, creating a cohesive aesthetic across every opening in the home.

In addition to modern styling and expanded design flexibility, the Carbonite Collection offers a narrow 3 1/4-inch frame depth, allowing the entire collection to fit into standard frame depth across the replacement pocket, making the product family an ideal fit for both new construction and remodeling/replacement applications.
