1) Sealing function of insulating glass : Some hollow glass in the market is only sealed in a single way, that is, no butyl rubber is used. This kind of product can only ensure the sealing effect of 1-2 years. As long as the double sealing is used, it can ensure more than 10 years. The service life.
2) Thickness of single piece glass : Insulating glass is made up of two pieces of glass. The thickness of single piece of glass should not be less than 5mm, otherwise it will affect the overall function of the insulating glass.
3) Thickness of the air layer: The thickness of the air layer is as small as 6 mm, and the thicker the air layer, the better the function of the insulating glass. Our experience is that hollow glass with a 9mm or 12mm thick air layer is more cost effective.
