Insulated glass consists of two panes of glass separated by a space. The perimeter of the glass is sealed, allowing no movement of outside air into the space. The space itself can be filled with dehydrated air, or with a special gas.

Almost all flat glass produced today is Float Glass. It is shaped by drawing a wide sheet of molten glass into a furnace containing a bath of molten tin.

Water repellent treatment can be applied to automotive windshields, side windows, back windows, and side view mirrors. The product can provide glass with water repellent properties. During rain, the droplets of water bead up and run off the glass, which helps improve driving visibility and reduce traffic accidents. This product lasts for up to six months in the windshield wiper area, under normal driving conditions. This product is not designed to replace windshield wipers, it should be used in conjunction with windshield wipers to maximize driving visibility.

Tempered glass is made by heating flat glass to approach its softening temperature and suddenly chilling with jets of cold air, which distributes compression stress on the glass surfaces while tensile stress in the center. The counteraction of compression stress and tensile stress provides tempered glass times strength than normal glass. When broken, tempered glass forms oblique bean size granules to reduce damage to human bodies. Tempered glass also withstands quick temperature changes.

Laminated glass is manufactured by permanently bonding two or more layers of clear or tinted glass with one or more interlayers of tough, polyvinyl butyral (PVB) resin sheeting in an air autoclave under heat and pressure to create a single, solid construction. Laminated glass is stronger and can withstand more impact. When laminated glass is broken, the fragments will keep sticking on the interlayer and won't scatter.
