For a home gym where weights are going to be dropped, what is the difference between 8mm Sport-Lock Rubber & 1/2" Rubber Gym Tiles?

The difference between our 8mm Sport-Lock Rubber Tiles and our 1/2" Rubber Gym Tiles is that our Rubber Gym Tiles are vulcanized, meaning they are non-porous and denser. So when dropping weight on either tile, our Rubber Gym Tiles will be better suited to absorb the shock of the dropping weight better protecting your subfloor.
