I am looking for mat-flooring for a high school weight room. Is 1/2" thickness thick enough?

Our 1/2" Rubber Gym Tiles have been used in high school and college weight rooms with great success. Our 1/2" Rubber Gym Tiles are our best flooring for Olympic lifting, which is common in school gyms. The tiles are very durable and shock absorbent. Being non-porous, these tiles are very easy to clean and disinfect, which is a must when being used in public gyms.
