I did one layer on the bottom and one on top with csm and then a 6oz. It is recommended to have 8oz total as a min. Also depending on what size wood you are using. I used 5/8 bcx. If you have webbing of bulkheads and stringers at 16-20 inches you could get by with 1/2". Looking at weight adder between 1/2 and 5/8 per sheet is not very much. I think it may be 10#
