MI Windows and Doors Expands Premium Product Portfolio with New Carbonite Collection
MI Windows and Doors, one of the United States’ leading manufacturers of precision-engineered and energy-efficient windows and doors and a member of the MITER Brands family, has announced the launch of the Carbonite Collection, a new premium line of black-on-black vinyl windows and doors designed to meet the growing demand for contemporary aesthetics, superior durability, and enhanced performance in residential construction and renovation projects.
The introduction of the Carbonite Collection marks a significant addition to MI’s expanding portfolio of premium products. Scheduled to launch in Summer 2026, the collection combines modern design elements with advanced color technology, offering builders, architects, remodelers, and homeowners a comprehensive solution for creating striking exterior and interior spaces.
As black-framed windows and doors continue to gain popularity across residential architecture, manufacturers are increasingly challenged to deliver products that not only achieve the desired visual appeal but also maintain long-term durability and energy efficiency. MI’s Carbonite Collection has been developed specifically to address these needs, offering a range of products engineered to perform in diverse climates and architectural styles.
The initial Carbonite Collection lineup will include several of MI’s most popular window products, including the 1620 single-hung window, picture windows, the 1630 horizontal slider, and fixed window configurations. In addition, the collection introduces three new offerings designed to broaden the company’s premium product portfolio: the 3075 Casement window, the 3065 Awning window within the V3000 Series, and the new VX4500 Moving Glass Wall system.
According to MI Windows and Doors, the collection reflects the company’s ongoing commitment to product innovation and customer-focused design.
“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.”
One of the defining features of the Carbonite Collection is its use of premium capstock color technology. Capstock has become the preferred solution within the industry for dark-colored vinyl windows and doors because of its ability to maintain color stability and durability while improving thermal performance.
Unlike conventional vinyl products, capstock technology incorporates an advanced outer layer that enhances resistance to heat absorption and environmental exposure. This technology allows dark-colored window and door systems to retain their appearance and structural integrity over time while benefiting from the inherent energy efficiency and low-maintenance characteristics associated with vinyl construction.
By utilizing capstock technology throughout the Carbonite Collection, MI aims to provide customers with products capable of delivering the sleek appearance of black frames without compromising durability or performance. The result is a product line that balances modern design trends with practical long-term value.
Among the most notable additions to the collection are the new V3000TX Casement and Awning platforms. These products have been designed with thinner frame profiles, enabling larger glass areas and maximizing natural light. The slimmer sightlines create a clean, contemporary appearance that aligns with current architectural preferences while enhancing outdoor views.
The expanded glass area also contributes to a brighter interior environment, an increasingly important consideration for homeowners seeking to create open, welcoming living spaces. By reducing the visual presence of the frame and emphasizing the glass surface, the new products help support modern architectural styles that prioritize simplicity, transparency, and strong indoor-outdoor connections.
Another major highlight of the Carbonite Collection is the introduction of the VX4500 Moving Glass Wall system. Designed to accommodate large openings and support seamless transitions between interior and exterior spaces, the VX4500 addresses the growing demand for expansive glass solutions in modern residential design.
The system offers exceptional design flexibility through a variety of configurable layouts, including multi-track, pocket, and corner configurations. These options allow architects and builders to create large unobstructed openings that enhance connectivity between living spaces and outdoor environments.
As homeowners increasingly seek flexible living arrangements that blend indoor comfort with outdoor experiences, moving glass wall systems have become a defining feature of many contemporary homes. The VX4500 is intended to meet this demand while providing the performance, durability, and visual consistency associated with the Carbonite Collection.
The inclusion of the VX4500 also strengthens MI’s broader product offering by creating a complete black-on-black capstock portfolio across multiple window and door categories. This enables homeowners and designers to maintain a cohesive aesthetic throughout an entire residence, regardless of the size or type of opening.
Beyond visual appeal, the Carbonite Collection has been engineered with practical installation considerations in mind. The entire product family features a narrow frame depth of approximately 3¼ inches, allowing the collection to fit standard frame depths commonly found in residential construction.
This design characteristic makes the products suitable for a wide range of applications, including both new construction projects and replacement or remodeling installations. Builders can integrate the collection into modern home designs, while contractors and homeowners undertaking renovation projects can benefit from simplified installation and compatibility with existing structures.
The versatility of the collection positions it as an attractive solution across multiple market segments, from custom residential construction to large-scale housing developments and home improvement projects.
The launch of the Carbonite Collection reflects broader trends within the residential building products industry. Homeowners are increasingly seeking products that combine energy efficiency, durability, and contemporary design, while builders are looking for solutions that simplify installation and provide long-term performance.
By expanding its premium product lineup with advanced color technology, modern operating styles, and innovative glass wall systems, MI Windows and Doors is responding directly to these evolving market demands.
As the collection becomes available in Summer 2026, MI expects the Carbonite Collection to strengthen its position within the premium window and door segment while providing customers with greater design flexibility and performance options.
With its combination of advanced capstock technology, expansive glass solutions, contemporary aesthetics, and installation versatility, the Carbonite Collection represents a significant milestone in MI Windows and Doors’ ongoing commitment to innovation and product excellence. The launch further reinforces the company’s strategy of delivering high-performance building products that meet the changing needs of today’s residential construction and remodeling markets.
