Aluminum is perfect for the realities of Russian winter, because it is not exposed to corrosion. As the studies show, the strength of the aluminum profile is 7 times more than wooden, and 3 times — plastic. That is why cold glazing of balconies is very popular among Russians. Aluminum has a relatively high thermal conductivity, so there are two types of profiles on the market, namely: “warm” and “cold”. The manufacture of a cold profile goes much less than effort, time and effort, therefore its cost is lower. In this regard, the cold glazing of balconies and loggias can be inexpensively.
