Important affects the stiffness of the floor, laying a pitch lag, the amount of timber used for the lag. The optimum distance for office and residential buildings – up to 700 mm. For technical – should be considered overhead, but by 400 mm. Timber must be treated ognebiozaschitnoy impregnation. Its dimensions shall be not less than 150 * 50 mm. At what he had "placed" vertically (150 mm in height). Go to the bottom joists attached sheet metal (black, thin metal, primed or painted).
Sometimes manufacturer uses the average thickness of metal (1-2 mm.), which is hermetically sealed (budget module does not apply where it (the metal) at the bottom just do not – there is the bare board). On the joists laid flooring. It can not be edged, but without the wane (bark) and treated ognebiozaschitnym solution, with a thickness of 25 to 40 mm. It fits neatly together. It fits on top of sheets of DSP (16 mm.
Thick) or water-resistant plywood. Other materials (Thin DSP, DSP, just plywood is cheaper, but they quickly gain moisture and become unusable.) DSP fit to the linoleum. Insulation sex – thick mineral wool laid in accordance with the regional calculations from 100 to 250 mm. (Usually 50 mm. thicker walls) and has a polyethylene vapor barrier. Residential building modular As should be properly and securely? Every piece of the floor can save you – place less often lags – the floor will be a little play, but endure, put floor boards with a gap – just okay, but it may eventually deform the DSP, or a heavy table leg will fall, for example.
