Tyrol Edge and Tyrol Contour advance the platform's design flexibility while preserving its leading energy efficiency edge, with whole-window thermal performance up to R-11 (U-0.09). These updates reflect Alpen's ongoing focus on making high-performance glazing more accessible, practical, and architecturally versatile. Alpen replaced traditional double glazing and steel reinforcements with lightweight multi-pane AlpenGlass IGUs and fiberglass composites, reducing weight, increasing thermal performance and enabling slimmer, larger windows. These innovations support both design freedom and affordable energy performance to meet evolving building codes and Passive House standards. "Alpen's upgraded Tyrol line is North America's most advanced composite window," said CEO Andrew Zech, Alpen CEO.
