Double-layer hollow laminated glass can be said to be a masterpiece of home decoration door and window glass. It not only inherits the good heat insulation of hollow glass and the sound insulation of laminated glass, but also improves the two properties, thus becoming the new favorite of many consumers who pursue performance. But as a relatively fresh thing, consumers and even practitioners have some doubts: the laminated surface of hollow laminated glass should be placed indoors or outdoors? What are the advantages and disadvantages? How to determine the thickness of hollow layer? How to determine the thickness of the glass?

When the sun room with double hollow laminated glass, laminated surface should face indoor or outdoor? There is no objection to this, all practitioners believe that the adhesive surface should be installed downward, to prevent the glass from breaking when the debris injury accident.

Double-layer hollow laminated glass is used on doors and Windows. Should the laminated glass face indoors or outdoors? Many project curtain walls put the laminated surface outside, so as to prevent the accident of falling objects, but there are some exceptions. For example, some low-level users of home decoration do not have to consider the risk of safety glass falling; At this time, you can also put the adhesive surface indoors, and the heat insulation is relatively good. Because in summer, the indoor glass feel temperature will be lower than the outdoor surface is laminated surface.
From the perspective of sound insulation, the sound insulation of doors and Windows mainly depends on the total thickness of the glass, and the thicker the double-layer hollow laminated glass, the better the sound insulation. If it is 5+ hollow +5 glass in a certain audio frequency will amplify the transmission of sound, sound insulation is less than 8mm single glass, more than 5+PVB+5 laminated glass, because the film will filter out a large part of the audio frequency.
