Length and width tolerances of insulating glass table. The length or width of the tolerance (mm) L <1000 ± 2.01000≤L <2000 + 2, the thickness of the insulating glass -3L≥2000 ± 3.0③ tolerance table. Glass thickness Nominal thickness (mm) Tolerance (mm): hollow glass nominal thickness of two glass thickness and the thickness of the spacer frame. ④ hollow glass two diagonal tolerance table. The difference between square and rectangular hollow glass diagonal should not exceed 0.2% of the average length of the diagonal. Double insulating glass sectional view of the structure shown in Figure. Insulating glass can 3,4,5,6,8,10,12mm thick slices of the original glass, air layer thickness can be 6,9,12mm interval. The thermal conductivity of glass is 27 times that of air, hollow glass, as long as the insulating glass is sealed, Weihai hollow glass, hollow glass in the best insulation. Between the glass and the glass insulating glass, and leave some space. Box filled with desiccant to ensure dryness of the air between the glass sheets. Two spaced hollow glass is generally 8mm. 5mm glass insulating glass _ Yaohui quality assurance (Advisory) _ Weihai hollow glass provided by Jinan Glass Co., Ltd. Yaohui. Jinan Yaohui Glass Co., Ltd. (www.jyhhc.com/) Shandong Jinan, architectural glass leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
