Generally used as a railing glass toughened glass, sandwich toughened glass, wire glass and other several, in the choice of glass guardrail glass thickness, according to different space and national standards, the general balcony glass railing glass thickness is not less than 12mm. When choosing the thickness of glass guardrail, there are two standards: The first is the "building decoration engineering quality acceptance Code" GB50210-2001 article 12.5.7, this article stipulates that the guardrail glass should use the thickness of not less than 12mm toughened glass or toughened laminated glass, when the glass is located in the building height of 5 meters and above, should use toughened laminated glass. Another regulation on the glass thickness of the glass balustrade is "Building glass Application Technical Code" JGJ113-2009, which stipulates that the selection of glass thickness is related to the size of the glass area. Generally speaking, the larger the single piece of glass, the thicker the glass should be. At the same time, it is stipulated that the nominal thickness of tempered glass is not less than 5mm or the nominal thickness is not less than 6.38mm laminated glass, and the thickness of glass under horizontal load is not less than 12mm tempered or not less than 16.76mm tempered laminated glass. When the lowest point of the glass balustrade is 3m and above, 5m and below 5m, toughened laminated glass with a thickness of no less than 16.76mm is used. According to the above two specifications, we can conclude that the glass thickness of the glass guardrail should be at least 12mm above, whether it is laminated glass or toughened glass to meet the minimum standard. When we decorate our own houses, in the choice of balcony glass guardrail glass for safety, we should choose a glass thickness of at least 12mm above.
