Ultra-white U-shaped glass has become a mature glass processing product. Its delicate surface scatters incident light, is transparent and has a hazy feeling. It has been widely used. U-shaped glass is light-transmitting but not see-through, has good lighting and energy saving, and has the characteristics of light transmission, visibility, heat insulation, sound insulation, and environmental protection. It is widely used in every corner of the building and can greatly improve the quality of space decoration.
It can be widely used in non-load-bearing interior and exterior walls, partitions and roofs of industrial and civil buildings such as airports, stations, stadiums, office buildings, hotels, residences, greenhouses, etc.
U-shaped glass installation method:
- Single installation: Wings facing outward (inward), often used; wedge-shaped structure, fitting each other; wedge-shaped structure, interlocking;
- Double-layer installation: Wings are arranged in pairs at the joints, often used; wings against wings, often used; zigzag arrangement; wings staggered arrangement; arc arrangement;
