I think I have about 150sqft of Teak, its 3/4" and it weighs about 5lbs per sqft. Its very heavy and very nice wood.
Janka Hardness Test Ranges from soft to hard 22-5060 (pounds-force) = Teak rates 3540
I have 300sqft of Cherry, its 1/4", probably weighs less then 1lbs per sqft. Only real benefit is its light weight
and its a much warmer color than the teak.

Just comes down to practicality or warmer looks
