Differences Between Acrylic & Tempered Glass Backboards

Acrylic is soft and tempered glass is hard
Acrylic is a very soft material. Over time, it will accumulate little scratches in the from scuff marks. This can give the board a dull or dirty look that can not be washed away. Also, lower quality acrylic backboards can attract mildew that will make the backboard look yellow and dingy. Tempered glass, like your car windshield, is very hard and will resist scratching. The backboard will remain clear for the life of the backetball system. Also, because tempered glass is more rigid, you will not see drum-head effect that deadens the rebound on acrylic backboards.

Acrylic is light and tempered glass is heavy
Tempered glass weighs approximately 4-6 times as much as acrylic. This gives the entire system more mass making it less susceptible to movement. Imagine throwing a rock at cinder block and then throwing that same rock at a piece of wood. Which would move more?  

Rebound Response Experiement
Acrylic was the clear looser with only a 38% rebound response (some manufactures use thinner 3/8 acrylic which was not tested). 1/2 inch glass was the winner beating 3/8 inch glass by approximately 9% with a 69% rebound response.
