In the NF DTU 52.10 standard, which is a French standard, a standard specification items are recommended for the application of screed and flooring or sealed under-tile insulation pads in the context of the construction of works designed to contribute to thermal insulation and sound insulation.
Suspended floors are often insulated to offer reduced thermal mass and respond quickly to the heating system. In the case of suspended concrete, the insulation is installed on the deck, under the screed or wood cladding. Suspended wood floors are normally insulated between joists.
Floating screeds are unbonded screeds, but are usually laid over a layer of insulation. It is mainly used in buildings with underfloor heating or where acoustic or thermal insulation is required. Requires a thickness of 50-65mm or even up to 75mm for heavily loaded floors.
The materials covered by this standard are: screed or floating plates and all components necessary for the application of sealed under-tile insulation pads, such as floor covering, repair materials, thin acoustic underlays, spiked plates, strip assembly, separation layer and the like. The selection of these materials is included in the section of the standard titled “General criteria for material selection”.
The NF DTU 52.10 standard also includes technical information on soil classification, post-flow dynamic stiffness increase and loading resistance.
floating floor to subflooris an unfixed floor, instead the floor covering, which is usually chipboard, plaster or cement fiber boards, floats above the insulation layer. In general, particle board is a lightweight construction form in which gypsum or cement fiberboard floor panels float on top of a rigid insulation layer. Floating floors are especially used when renovating an existing building. Because it's fast, lightweight and easy to install, it's thinner than screed options and allows fast heating response times.
Among the numerous test, measurement, analysis and evaluation studies that our organization provides for businesses in various sectors, with its trained and expert staff and advanced technological equipment, test services for the application of insulation pads under screed or floating plates and under sealed tiles within the scope of NF DTU 52.10 standard. also gives.
