Must Use The Scope Of Tempered Glass

Safety glass must be used in the following 11 environments:

1. When the height of the roof glass is greater than 5M from the ground, toughened laminated glass must be used, and the thickness of the laminated film should not be less than 0.76mm.

2. Sightseeing elevator and its peripheral protection.

3. Ground panel used to withstand pedestrian walking.

4. Windows are opened outside buildings with floors 17 and above. If insulating glass is used, safe insulating glass should be used; In the case of double glazing, both sides are toughened glass in principle; Safety glass is not required for sliding Windows (glass area less than 1.5 square meters)

5. Window glass with an area of more than 1.5 square meters or floor-to-ceiling window with the bottom edge of glass less than 500mm from the decoration surface; Regardless of the number of layers and height, glass conforming to this line shall be safety glass. No matter the size of the frameless glass door, the thickness of tempered glass should be no less than 10mm.

6. Glass curtain wall refers to the glass curtain wall composed of glass ribs and glass panels, you do not need to use toughened glass. Commonly used metal frame glass curtain walls (including point glass curtain walls) must use safety glass.

7. Aquarium and swimming pool observation window, observation hole; Toughened laminated glass should be used for underwater glass.

8. Entrances and exits of public buildings, foyers, etc. If the ground floor entrance foyer of the dwelling unit is enclosed by a glass partition, the glazing shall be safety glazing.

9. Indoor partition, bathroom enclosure and screen. If the window sill is lower than the stipulated requirements (less than 0.8M for public buildings, less than 0.9M for residential buildings), if the lower part of the window is set equal to the height of the railing, there are fixed Windows with window frames around as protective measures, and the glass is laminated glass, the thickness is not less than 6+6mm, then there is no need to make the railing. If the height of the window is below 0.9M, it must be made of railings. Residential balcony sliding doors with glass area less than 1.5 square meters can be done without safety glass.

10. Stair, balcony, platform corridor and atrium corridor; For glass railings that do not bear horizontal load, it is recommended to use tempered laminated glass. If the glass can be fixed around the glass and is only used for enclosure, the thickness of the glass railings bearing horizontal load is recommended to be 6+6mm. When the glass is located at a building height of 5M or above, the thickness of tempered laminated glass should be no less than 12mm (the specific thickness should be determined according to the calculation of thrust and span, etc.).

11. Tempered laminated glass shall be used for other parts that are vulnerable to impact or impact and may cause human injury. The recommended thickness of ordinary glass canopy is 12 (top) +8 (bottom) mm, and the recommended thickness of glass sheet is 6+6mm.

Because the selection of glass should pay attention to its large allowable area and thickness, the relationship between types, the structure professional has calculated the wind load of each height of multi-storey and high-rise buildings, you can safely use toughened glass.
