As shown practices, installation of wood flooring in the room 20 m2 within a couple of hours. The cost of installation – $ 10.08 m2. Parquet board a "floating" manner laid necessarily on a special substrate that separates the board from basis (floors, screeds, etc.). Substrate serves several functions: eliminates minor bumps and prevents the spread of air and noise impact. But at the same time solves one more very important task, which almost never mentioned – is the separation between sing cement or plaster base and floor covering. This layer is needed for the following reason. The degree of deformation temperature and humidity floor of the floorboard and the ties are very different, so because of expansion or reduction of coverage will "crawl" on ties or high-precision leveling coating made on the basis of cement or gypsum, and erase it.
As a result of a year – two operating under the flooring will be formed cement or plaster dust, which inevitably through the cracks in the coating appears on the surface of the floorboard. For substrates using different materials: wool-felt board, composite materials, polyethylene foam, cork sheet, extruded polystyrene and other materials. It should be noted that most popular was the substrate Tuplex. This substrate meets the modern requirements for soundproofing rooms, provides overall good noise reduction – up to 20 dB. Also has good substrate Tuplex thermal insulation properties (thermal conductivity is 0.044 W / (m * K) and excellent vapor barrier properties. A common mistake – the desire to make a thicker substrate, for example, lay it in two layers.
In this case, actually increase sound insulation properties, but the point load support may shrink (in some cases doubled or more), which is why there is an additional vertical outdoor play coating, which leads to breaking of locks boards. In some cases, the floorboard can be laid on the joists and beams, which must be sound, dry and not deformed, otherwise it will be movement of center boards, the floor will squeak, and, ultimately, there will be the emergence of defects. The space under the beams should be well ventilated to avoid accumulation of water vapor. More feasible option pre-laying layer of plywood on the joists, to which then produced gluing boards. In some cases, permitted and attachment to the sleepers, which use nails or staples. Beams and joists must be based on increments of 60 cm, and the parquet board should to be fat – not less than 20 mm. When laying must perform a number of conditions: if the premises are claimed to be laying floorboards, is located on the premises where it is possible an intense selection of steam (Eg, pool), be sure to arrange vapor barrier layer. For this purpose, as a rule, use special vapor barrier film, installation of parquet is recommended under normal conditions: temperature of 20-25 C, relative humidity – from 40% to 60%.
