Tokyu Plaza Harajuku “Harakado” features Irregular Heat-Reflective SGP Laminated Glass as its core curtain wall material, which is key to achieving the building’s “shattered mirror” visual effect and meeting the functional demands of a commercial building in Tokyo’s core district.
Irregular Heat-Reflective Design: Each glass panel is custom-cut and heat-bent to form irregular multi-faceted shapes. Combined with the heat-reflective coating, it creates a “shattered mirror” refraction effect under Tokyo’s sunlight, reflecting the sky and surrounding streetscapes as light angles shift, making it a highly recognizable visual landmark in the Harajuku district.
SGP Laminated Safety Protection: The SGP interlayer has over 5 times the tear resistance of standard PVB film, holding glass fragments securely in place if damaged to prevent falling debris risks, suitable for the high-footfall environment of Tokyo’s core commercial area. It also blocks UV radiation and reduces solar heat gain, lowering indoor cooling energy consumption and mitigating the impact of summer heat on commercial spaces.
Commercial Space Adaptability: The glass’s high reflectivity protects the privacy of interior shops while allowing pedestrians to glimpse the interior, enhancing commercial visibility. The irregular multi-faceted design also reduces the building’s visual weight, ensuring the transparent curtain wall blends seamlessly with the trendy atmosphere of Harajuku.
