The double-glazed window occupies 70% of the area of ​​the window and to a large extent affects the heat protection and noise insulation of the whole structure. Double-glazed windows can be different. Their types mainly depend on the number of air chambers. That is why the main question that arises when choosing a profile system is how many glasses should be installed in plastic windows: 2 or 3 glasses?
There may be more, and sometimes single glazing is used at all, but it is between these two structures that doubts arise most often. What is the difference between two-chamber and three-chamber glass?
Thermal protection and noise reduction
The main idea of ​​the cameras in the glass is that the air that is between the panes serves as an additional barrier to frost. Cold streams, bumping into each new barrier, gradually warm up, giving away a negative temperature to these very obstacles. It is logical that the more of these obstacles, the warmer will be in the room. In this race, undoubtedly, the three-chamber double-glazed window will win, it is more warm and energy-saving. This is also proved by various physical indicators, for example, the coefficient of heat transfer resistance.
This number is detected by a simple calculation and serves to designate the insulating properties of window structures. The coefficient of the two-chamber profile is on average equal to - 0.62. If you live in the northern part of the country or just want to insulate a balcony and a loggia, the answer to the question of how many glasses should be installed in new plastic windows: 2 or 3 glasses, is unequivocal. Only a three-chamber, two-chamber glass unit will not give you such a thermal effect. Security This parameter can be assessed from two sides: household security and protection against hacking.
It is possible to say that windows are safe for others in the event that when breaking them as little fragments are formed. In this situation, everything is clear, the more glasses - the more and fragments from them. Intrusion safety is a more complex issue. On the one hand, the three-chamber glass unit is much more difficult to break, on the other hand, it puts more pressure on the fittings and makes it more useless because of what the robbers will most likely not even have to break the glass.
They can just break the sash. In any case, if you are greatly worried about the security problem, it is better to install laminated or tempered glass in your construction. Laminated glass is not broken in the conventional sense, and is covered with cracks. Hardened 6 times stronger than usual and is broken into small pieces of rounded shape. Both of these products will be safe for households and can complicate the task of robbers. Weight As already mentioned, a three-chamber glass pane strongly influences fittings. Its weight is much more two-chamber, this increases the load. In addition to fittings, the profile itself can be damaged.
He can quickly lose his form. The only solution in this case is a thickened metal insert in the inside of the frame. If you are not so much in need of especially insulated windows, still it is worthwhile to stop the choice on the two-chamber glass unit. With such a translucent design, the profile system will last longer, and you can achieve stunning thermal protection with an energy-saving window. In general, what to put in plastic windows: double or triple glazing is not as important as in the case of wooden structures. In such a situation, triple glazing is completely contraindicated.
The tree is much heavier than the plastic profile, which has voids inside. By itself, the sash of a wooden structure can weigh more than 6-7 kilograms, and a three-chamber glass unit will increase this weight to a critical figure. In addition, the three-chamber profile is not recommended to be installed on the lifting and sliding windows. The assembly of such a structure is opened thanks to your efforts, a multikilometer glass unit will only complicate the operation. The weight of a glass unit affects the usability of any window, but it is in these two cases that this indicator is of particular importance.
