I've recently been offered a quantity of Indonesian teak beams, which I plan to have milled into hardwood flooring. The beams are 3 in x 12 in x 12 ft.
How would you recommend I have these beams cut, to make a fair balance of economy of materials and fantastic final product? Is there any advantage to having a hardwood floor thicker than 0.7 inches? Should I absolutely have is t&g'd?
Part of this will be installed over a newly poured concrete slab with living space underneath. I've read that a 6 mil vapor barrier should be glued to the concrete, 3/4 inch plywood with 4 screws through into the concrete, and the wood floor nailed/stapled to the plywood. Would you agree? Is there something 'better' than 3/4 plywood as an underlayment for what I hope to walk on for the next 60 years? The rest of the floor will be nailed on 3/4 x 5 1/2 t&g subfloor, unless you can convince me to do it differently.
