Usually, plastic windows are made of 2 or 3 glasses, which have a thickness of 4 millimeters. Let’s first consider a simple technique that makes it possible to determine how much glass in the double -glazed window. Modern plastic windows are so high and their transparency is so high that it is quite difficult to determine how much a glass in the eye is quite difficult. A simple technique is that you need to bring a light match to the window and calculate how many reflections the fire on the glasses has. If you can see two double reflections, then glass 2, if three double, then 3.
To be expressed in a professional language, then the windows made of plastic with two glasses are called single -chamber, of three glasses is a two -chamber double -glazed window, because the number of cameras is much more important than the number of glasses. Two -chamber double -glazed windows that have three glasses are called double. It is thanks to the layers of inert gas or air in the windows of plastic and the sound and thermal insulation of the room from the environment is provided.
But let’s discuss the shortcomings. They are also present. As a rule, a double -glazed window has a thickness of 32 millimeters, despite the fact that a single one is 24 millimeters. The difference is about one and a half times. As a rule, this does not cause problems if you do not take into account cases when the window is installed in the opening with a thin wall. In addition, the weight of the wings at such a window is one and a half times higher, which is also a significant drawback, because it causes a greater wear of the mechanism where the wings are attached. Due to the fact that it mainly goes through heat radiation, the best alternative option in the past few years is the use of infrared glasses, which have a special spraying, which reflects thermal radiation back into the room.
If we take into account the use of technology such as downloading inert gas inside inter -stacol chambers, which makes it possible to make a double -glazed window for a lot already, while maintaining even more heat, it turns out that “greedy pays twice”. Simply put, if you install, plastic windows that are more expensive, then after a few of your costs will pay off in the form of funds saved on the consumption of electricity or gas for heating the room. In addition, such windows will last much longer.
If you summarize all of the above, we can conclude that no matter what the buyer has the income level, it is difficult to give unequivocal advice. But, be that as it may, if you have the opportunity to choose a more modern option, it is better to give preference to it.
