When it comes to creating stunning, energy-efficient spaces that seamlessly blend indoor and outdoor living, Alpen High Performance Products continues to push the boundaries of innovation. Their latest announcement has us particularly excited: the new 9-foot tall Grandline Sliding Glass Doors that combines taller sliding doors with better wind-load ratings and superior energy performance.
Reaching New Heights
For architects and homeowners pursuing Passive House certification or simply seeking the pinnacle of sustainable design, these new doors represent a remarkable achievement in building technology. The expanded height options – now reaching an impressive 9 feet – create dramatic visual impact while maintaining Alpen’s renowned thermal performance.
Strength & Views
The engineering behind these doors is particularly noteworthy. Designed to handle panel widths up to 52 inches and withstand wind speeds up to 120 mph, these sliding doors don’t just look spectacular – they’re built to last. Each panel can accommodate up to 40 square feet of glass, offering unprecedented opportunities for panoramic views and natural daylighting strategies in sustainable design.
Flexible Design
Available in 2-panel, 3-panel, and 4-panel configurations, these doors offer flexibility for various architectural applications. The bi-parting option is particularly appealing for projects requiring grand entrances or expansive outdoor living spaces. Complementing these doors are new handle options, including the sophisticated Signature 40.94 and Contemporary 40.70 styles, available in a range of finishes to match any design aesthetic.
Energy Efficiency
What sets these doors apart is their ability to deliver both form and function. While the views are expansive, the doors maintain exceptional energy efficiency – a crucial factor for projects targeting Passive House certification or net-zero energy goals. The larger glass areas maximize natural light penetration, potentially reducing artificial lighting needs while creating spaces that feel more connected to the outdoors.
For architects and builders working on high-performance projects, these doors represent an exciting opportunity to create striking visual statements without compromising on energy efficiency or structural integrity. Whether you’re designing a mountain retreat with panoramic views or a modern urban dwelling, these doors offer the perfect balance of performance, strength, and aesthetics.
