Protection against cold, Window and door - Chisinau, Moldova

Heatlosses can be divided into several subspecies conditionally:
1. The heatlosses happening through walls, a ceiling, a floor covering, doors and windows. this look received definition of transmission.

2. The heatlosses quantitatively equal to the heat necessary for heating of cold air coming to the room from the outside to room temperature.

3. The heatlosses happening at the expense of radiation when transforming energy of the thermal movement of particles to energy of radiation which, in turn, is concentrated in the infrared range of a range. As classical glass in this range is almost transparent, heatlosses because of radiation are rather big. Through window designs much more thermal energy (see figure 1), than through external walls, a roof or a floor covering leaves. Thus, v thermal insulation one of the defining moments of functional characteristics of the PVH window providing a comfortable microclimate of the house.
