Singapore R151 Project

In the subway side window project, an innovative approach was taken by using 2550*930 large format glass for the insulated glazing unit, making it the project with the largest side window size among current rail transportation products. The glass employed is Loweglass, which exhibits excellent thermal insulation properties. The glass complies with the requirements of the NF F31129 standard, satisfying all safety indicators. It possesses superior optical performance, with no optical defects across the entire surface, providing passengers with an ultra-wide panoramic view and enhancing riding comfort.
