The following eleven environments must use safety glass:

1, tilt assembly windows, all kinds of roofs (including skylights, lighting roof), ceiling when the roof glass high point from the ground is greater than 5M, must use tempered laminated glass, mezzanine film thickness should not be less than 0.76mm.
2, sightseeing elevator and its peripheral protection.

3, used to withstand pedestrian walking ground panel.

4, 17 and above the building outside the window. In the case of hollow glass, use safe hollow glass;Toughened glassSliding window (glass area is less than 1.5 square meters) does not require safety glass

5, the area of more than 1.5 square meters of window glass or glass bottom edge from the decoration surface less than 500mm floor-to-ceiling windows; Frameless glass doors, regardless of area size, should use tempered glass with a thickness of not less than 10mm.
6, full glass curtain wall refers to the glass curtain wall composed of glass ribs and glass panels, you may not have to use tempered glass. Common metal frame glass curtain walls (including point glass curtain walls) must be made of safety glass.
7. Observation windows and observation holes in aquariums and swimming pools;
8, public buildings entrance and exit, foyer and other parts. If the underlying entrance hall of the residential unit is glass partition, the glass must be covered with safety glass.

9, indoor partition, bathroom enclosure and screen. Below the requirements of the window sill (public construction less than 0.8M, residential less than 0.9M), if the lower part of the window is set the equivalent of railing height, surrounded by a fixed window window window as a protective measure, and the glass using laminated glass, thickness is not less than 6 plus 6mm, then no need to do the railing. If the height is below 0.9M to open the window, be sure to do the railing. The glass area of less than 1.5 square meters of residential balcony sliding doors can be without safety glass.
10, stairs, balconies, platform corridors and atrium columns; glass railings that do not bear horizontal loads, it is recommended to use tempered laminated glass, such as glass around can be fixed and only used for circumference, the thickness is recommended for 6 to 6mm to withstand horizontal load railings of glass, when the glass is located at the building height of 5M and above, should use the thickness of not less than 12mm of tempered laminate glass, specifically based on the thickness of the thickness, etc.
11, vulnerable to impact, impact and other parts of human injury, glass rain canopy, glass hundred pages, etc. must use tempered laminated glass. General specificationglass rainpeng thickness is recommended for 12 (top) plus 8 (lower) mm, glass 100-page thickness is recommended for 6 plus 6mm.

Because the selection of glass should pay attention to its large use area and thickness, the relationship between types, the current structure of professional has calculated the multi-storey and high-rise buildings of the various heights of the wind load, can be assured of the use of tempered glass.
