Modern high-rise buildings rely heavily on curtain wall systems not only for architectural appearance but also for long-term structural and environmental performance. In today’s façade engineering industry, Performance Mock-Up (PMU) Testing has become one of the most important quality assurance processes before mass production and installation begin. For landmark commercial towers, airports, and unitized façade systems, a small design or installation issue can later lead to m

Why a 1.0 W/m²K Glass Specification Still Leads to an Energy-Inefficient Building Modern façade design is increasingly driven by sustainability targets, energy codes, and high-performance glazing specifications. Today, developers, consultants, and architects often demand glass with extremely low U-values such as 1.0 W/m²K or even lower, assuming that this automatically guarantees an energy-efficient building. But in reality, many completed buildings still perform far below ex

Modern high-rise architecture is rapidly evolving toward faster construction, cleaner aesthetics, and higher-performance façades. Among all façade systems, the Unitized Glass Curtain Wall System has become one of the most preferred solutions for commercial towers, airports, hospitals, and iconic skyscrapers worldwide. But while people admire the finished glass façade from outside, very few understand the detailed engineering, coordination, logistics, and installation methodol
