'Suspended' floors can also be realized by means of reinforced concrete beams, based on the supporting wall. In between the beams stacked blocks. Over blocks and beams running screed with a minimum thickness of 75 mm. On screed is laid membrane and extruded polystyrene foam (eg, Primaplex). Then, through the cushioning layer laid finish flooring. There are several ways to accommodate insulation: under the floor over the entire area, along the edges of plate horizontally along the edges of plates vertically from the inside.

Choosing insulation Key criteria when selecting insulation for the floors along the ground: the thermal conductivity. Must take into account long-term indicators, which is expected to have insulation at the end of life of the building (approximately 25 years) water absorption. This indicator should be as low as possible, for example, less than 0,5% by volume during the entire period of service; strength at 10 percent strain, water vapor permeability. This indicator is required for the risk of condensation installation simplicity and environmental friendliness: easy, clean material that is easily cut to the desired size, is not dangerous for health workers. The best indicators listed above, has a thermal insulation made from extruded polystyrene, in particular, plates Primaplex. The table shows the main characteristics of plates Primaplex.
