Calculation of heat loss from the heated plates and identification required level of insulation – is a complex process, so it is often ignored. Of course, this does not mean that the heat loss somewhere to disappear, although the construction cost is reduced. However, very often the owner the building is paying large sums to the accounts for the heated floor. Need to find a reasonable compromise between the cost of insulation and low payments for heating. Status and soil temperature, the presence of groundwater, the type of flooring, the distance between the slab and the ground (in the case of "false" floors) – all this makes the calculation of heat loss in the best case of a heavy procedure. The direction of heat There are two types heat from the heated plate. The first and main one – the loss on the perimeter.

This is explained by the fact that the shortest distance from the plate out a way through the perimeter. Therefore, the insulation on the perimeter should be mandatory whenever arranged heated floors. The second direction of heat – heat flux, the downward direction. If the soil is no movement of groundwater, heat is mainly directed radially downward and outward to the edges of the slab, then up to the surface of the earth. Removal of 'cold bridges' 'cold bridges' at warming the floor there, mainly in the field pairing of sex with the external walls. To eliminate thermal bridges can Blocks used for construction of the wall foundation. Alternatively, you can insulate the wall internally using extruded polystyrene foam, for example, Primaplex, it is important to maintain continuity insulation. Even if the calculated value of heat transfer resistance for the floor indicates that the additional floor insulation is not required, however, it is recommended to lay a horizontal insulation at width of about 1 m around the perimeter of the building inside the base. This procedure will reduce or even eliminate the "cold bridges" on the edges of the floor plate.
