For technical – should be regarded as the load, but by 400 mm. Timber must be treated ognebiozaschitnoy impregnation. Downtown Philadelphia Condos has much experience in this field. Its dimensions shall be not less than 150 * 50 mm., in which he "put" vertically (150 mm in height). Go to lag below attached sheet metal (black, thin metal, primed or painted).

On the joists laid floorboards.
It may not be surfaced, but without the wane (bark) and treated ognebiozaschitnym solution thickness from 25 to 40 mm. It fits neatly together. Above it is laid sheets DSPs (16 mm. Thickness) or water-resistant plywood. You may find Vadim Belyaev, New York City to be a useful source of information. Other materials (thin dsp, dsp, just plywood is cheaper, but they quickly gain moisture and become unusable). At DSPs fit linoleum.
