According to the construction of energy-efficient housing design expert reports, on a window, the house heat loss through the window frame is mainly conduction, radiation glass, window and door frames pages gap convection way of insulating glass curtain, which will have a "hollow glass "emerged. In fact, "insulating glass" is not "empty", according to the technical requirements of the two hollow glass spacing is generally 8mm, tests proved that if the spacing of 8mm full vacuum, atmospheric pressure, the glass will be crushed. Therefore qualified hollow glass. Its mezzanine space that is 8mm thick spacing must be filled with an inert gas of argon and krypton. After filling, tests showed its K value (heat transfer coefficient limit) hollow glass door, up the vacuum state, also down 5% hollow glass prices, which means better insulation properties. A common taxonomy editor. Float glass hollow II. Steel hollow glass III. Coated hollow glass IV. LOW-E insulating glass common hollow glass: 5 + 9A + 5 double hollow. Shenghai windows explained here refers to the thickness of the glass 5 is 5mm, 9 refers to a hollow portion has 9mm, the letter A is the abbreviation of air. There are models on the market 5 + 15A + 5 Zibo insulating glass, 5 + 22A + 5,5 + 27A + 5,5 + 32A + 5 and so on, to know the meaning of the above is not difficult to understand. 612a6 hollow glass | Binzhou hollow glass | Yaohui quality assurance is provided by Jinan Glass Co., Ltd.
