Discover the ALU-Millennium Profile

The Perfect Blend of Style and Functionality

We’re excited to introduce the ALU-Millennium series, featuring the slimmest aluminum window and door profiles on the market. Designed to enhance both historic renovation projects and contemporary residential and commercial architecture, offering a wide range of applications with profiles as narrow as 1-1/8 inches.

With roots in designing steel windows and doors, our European factory stands as the most reliable manufacturer of metal windows and doors. Our innovative solutions feature industry-leading slim profiles that maximize natural light and energy efficiency, seamlessly blending classic architectural elements with modern functionality.

One standout feature is our first aluminum hinged door with a lockbox, a unique design element previously exclusive to steel doors. While the look of steel is hard to replicate, our Millennium Series Narrow Profile Aluminum Windows & Doors come remarkably close, also delivering a stunning aesthetic and ability to create a “T” profile exclusive until now to steel, and various radius and gothic designs that steel cannot otherwise procure. ALU-Millennium’s thermal performance can surpass that of steel, making our profiles a superior choice in energy efficiency.

Inspired by the narrow steel profiles of early 20th-century windows, our designs honor historical aesthetics while addressing today’s demands for improved insulation and energy performance. Developed in collaboration with leading architects, our minimalist frames ensure maximum daylight utilization and meet the highest standards of energy efficiency—perfect for projects that respect the past while embracing the future, and those also using steel or bronze, as all products are manufactured in our European factory guaranteeing perfectly matched finishes and cohesive design.
