U-shaped glass, also known as channel glass, is a profiled architectural glass that has been used abroad for nearly 40 years. Its U-shaped cross-section gives it greater mechanical strength than ordinary flat glass. It offers good light transmission, sound and thermal insulation, reduced metal framing requirements and straightforward installation. Applications include interior and exterior walls, partitions, roofs and windows. Design considerations include: 1, Surface finishes include standard fine-textured, clear and colored glass; finishes other than the standard fine texture must be specified. U-shaped glass is non-combustible and can provide fire resistance; special requirements must be specified in accordance with the relevant standards. 3, Refer to the assembly methods for installation. Common arrangements use paired double rows with the flanges facing inward to form a cavity, or a single row with the flanges facing inward or outward. 4. For exterior walls, installation length depends on local wind loads, height above ground and other factors.
