The sheet are about 1/4" thick and there is a plastic film on one side.
Flew the San Juan's for years...Some of the best sloping on the planet!!!!!
When i went to my lowes,they had some foam that looked like what you guys said,I just have one question......does it come in a box or is it tied in plastic???The kind i can find is tied with plastic.
