Design essentials of insulating glass


1. Groove aluminum type double sealing butyl adhesive for the first sealing; The second sealant is mainly polysulfide glue and silicone glue. Polysulfide adhesive is suitable for window or framed glass curtain wall; Silicone glue is suitable for hidden frame glass curtain wall, wood window is avoided with silicone glue as the second sealing, because of its anti-wood preservative ability is very poor.

2. The interval aluminum frame should adopt continuous long pipe elbow type, and the joint should be sealed with butyl adhesive. Interval aluminum frame such as the use of four corner plug type, its various joints are also applied to butyl glue to do sealing treatment, made of glass, the service life is not as good as the former. When the second sealant is made of silicone glue, the insulating glass of the four corner insert type interval aluminum frame should not be used.

3. The change in the internal pressure of the air layer of insulating glass deforms the glass and leads to image distortion. Therefore, the air pressure of the air layer must be adjusted when it is used at an altitude of 1000m or above, and the glass supplier should be consulted when placing an order.

4. The heat insulation performance of the window is closely related to the window frame material, so the window frame material with good heat insulation performance should be selected.

5. If used as lighting ceiling, interior side glass should be laminated or explosion-proof film.

6.Low-E insulating glass, the membrane surface is located on the second or third side, should be selected according to the design needs. If the design of insulating glass must be in the form of large and small pieces, the membrane surface must be placed on the third side.

7. The very maximum allowable area of the insulating glass supported on four sides is 1.5 times the very maximum allowable area calculated according to the thickness of two single glass sheets.

8. The following technical performance requirements shall be put forward during the architectural design: heat preservation performance, heat insulation performance, sound insulation performance, lighting performance, sealing performance and weather resistance performance.
