1. To ensure energy-saving effect of the Low-E glass coating, the coated layer of the bent tempered insulated glass must be sealed between the insulated glass panes.

2. The Low-E coating between the insulated glass panes is usually coated on the inner side of the exterior glass pane.

3. As many buildings now adopt wavy exterior glass curtain wall built with bent tempered Low-E insulated glass, it requires the convex and concave bent tempered glass to be connected one by one to ensure that the Low-E coatings of the bent tempered insulating glass are on the same side for the realization of wavy glass curtain wall and the performance of the design.

4. With existing bending glass tempering machine, the glass bends upwards during processing. To prevent the ceramic roller from scratching the coating, the coating of Low-E glass faces upwards in the heating furnace (with the curve's center above the horizontal plane of the bending mechanism ), forming concave glass. However, the glass surface of continuous wavy Low-E or S-bend glass (with the curve's center under the horizontal plane of the bending mechanism) can only be achieved through convex bending glass tempering furnace.
