Tempered is stronger. Tempered glass has a minimum surface compression of 10,000 pounds-per-square-inch (psi) and minimum edge compression of 9,700 psi, according to ASTM C1048. That makes it about four times stronger than annealed glass.Are double pane windows tempered glass?
Double-pane windows are made from a wide variety of glass types.
