Hot and humid climate cycle and climatic test after 320 cycles of hollow glass roof, high temperature, test after 224 cycles of hollow glass article, dew point test after test. A total of 12 samples, at least 11 with no condensation or frost hidden box walls the choice of insulating glass, insulating glass must be done second sealant must use silicone sealant, and with structural glazing sealant compatible, that the two must be mutually compatible sealant. When using a silicone structural glazing sealant hollow glass, the best insulating glass sealant layer order also use the same factory silicone sealant. Hollow glass during use of hollow glass, when the ambient temperature is lowered so that the glass surface temperature was lowered to the dew point within a layer of dry air when the surface layer of dry air will produce dew or frost. Due to condensation or frost glass surface and affect performance insulating glass. If the guarantee air layer at minus 40 degrees Celsius without condensation, hollow glass in the course of the air layer is not present condensation phenomena. lowe hollow glass _ Yaohui trusted (authenticated) _ hollow glass provided by Jinan Linyi Glass Co., Ltd.
