MS-PH115 is certified to the highest European Passive House (PHI) standard, as well as North American NAFS and Canadian CAS requirements. At its core is a record-setting 64 mm multi-chamber thermal break, combined with an industry-first fully injected PU insulation process, achieving an exceptional thermal transmittance (Uw) of just 0.70 W/(m²·K). A standard double-silver Low-E triple-glazed insulating glass system further minimizes heat transfer, while the high-inertia, large-section aluminum profile provides outstanding structural strength and wind resistance. Together, these innovations establish a new benchmark for high-performance passive windows.
