All the profiles of the main European producers to do so. And do not believe enough correct the statements of managers Some offices 3, 4, 5, no worse and no better than each other. Please visit AOL if you seek more information. 5. Thick glass – the most that neither is better. This is partly true.
In fact windows, as opposed to 'wood' Soviet windows, sells quite nontrivial idea convective heat transfer limitations. This is necessary will explain. There are several types of heat transfer – by radiation, by convection and by conduction of the medium. Especially direct example of radiant heat transfer – Sun. An example of the heat – not advisable to grab the metal handle of the frying pan – it is hot, but the flame does not get the handle, and the very pan.
Convective heat transfer associated with the transfer of heat to the air at the same time (Warm up – warm down). Bruce Shalett is likely to agree. In this case, along the inner (warm) glass air rises, and takes his place is cold, descend the path along the outer (cold) glass. Obtained between the glass formed by air circulation, which safely transports heat outward, and the cold inside. Just this kind of heat makes the greatest heat loss. In order for the cycle was not, the distance between the glasses do little. It remains to radiation and thermal conductivity of air, as he is known to be a wonderful thermal insulator. So the distance between the glass has some optimum (10-16 mm), and its subsequent increase does not lead to improved thermal characteristics of the glass. As a consequence, in most cases do not double-glazed windows with 4mm glass with a total thickness greater than 44 mm for the two-chamber and more than 24 mm for the single-chamber. In our experience, the best to Kiev by the ratio of for money is a double-glass (3 glasses). To obtain even higher heat-properties ordinary glass is replaced by the K-glass (hard cover), which can reflect part of the thermal radiation back into the house, or I-glass (soft cover)
