The issue of saving various resources excites any thinking and diligent host. In conditions when on the threshold of the next( already many and from the account lost, which) crisis, on the relevance of this topic comes to the fore. Given the proportion of our family budget accounted for the payment of utility services, it is worthwhile to understand what the so-advertised energy-saving windows are.
Let's say at once - this is not a myth, not another trick of marketers. In principle, any window reduces the heat loss of the structure, if the unit is assembled qualitatively, correctly installed, all cracks are filled and the glass is dirty( for example, insulated according to Swedish technology).With respect to traditional( "Soviet") wooden frames, the PVC window( regardless of type) can be called energy-saving. For example, seals, in contrast to putty, ensure reliable sealing of the glass, and the frame does not go "in misalignment" with time.
The feature of the energy-saving window
There is no fundamental difference from those plastic blocks, which are now practically installed by everyone. But there is one nuance - one glass in the package is not usual, but with a special coating. This is clearly seen in the figure.
The presence of such a "detail" allows to reduce heat loss through the window opening( in comparison with a conventional double-glazed window) by about half. Due to what? On the surface of one glass a special layer is applied, which is a reflector( screen) for heat rays. Consequently, all the heat energy that the heaters produce, remains in the room and does not "go" beyond its limits, to the street. It is elementary reflected from the special cover.
For lovers of indoor plants. Energy-saving windows in no way affect( negatively) their growth.
Advantages of
- The weight of the energy-saving window is smaller than that of a conventional PVC block. Accordingly, all moving parts of the structure( accessories) will last much longer.
- The fogging of the package is excluded under all conditions.
- This unit does not let the ultraviolet pass. Consequently, you do not have to often repair. For example, to change faded wallpaper, update the paint and so on. Sunscreen on the window may also not be needed.
Practical advice to
- Some firms go for "cunning".Advertising its window as energy-saving, in fact install a regular double-glazed window with a tint. Such a coating for heat rays is not an obstacle. But money is taken as a declared product. By the way, energy-saving costs about 700 - 900 rubles more than usual.
What to take into account
- You need to order energy-saving windows only in organizations with a good reputation. In addition, it would be nice to send additional information through acquaintances, as it is not a secret that often the positive feedback is trite paid by the interested party.
- When ordering, please read the product certificate. This, not the price, the main thing. And the cost should not be more embarrassing - in this case it is secondary. Only for 1 heating season in the private sector can significantly save on fuel and boiler operation, choosing a more gentle regime. For an apartment building, an energy-saving window is also only a "plus".In the rooms it will become warmer, and you will not have to think about how lime came out of the mold or mold. In addition, you do not have to systematically include heating appliances / appliances. Here is an overpay for such windows and will return.
- Before installing the masters of the blocks, you need to carefully examine them. Special cover must necessarily "look" inside the camera( if it's "I" -style).You can not exclude errors in the manufacture, so it's better to be safe and check the correctness of the assembly of the unit.
How to check glass for forgery
The coating refracts the beam. If it is on the glass, then from the thin object attached to it( pens, a stinger of a screwdriver), there will be a shifted reflection.
By placing a source of fire( lit match, lighter) to the glass, one can see the reflection of the flame. If it has changed the color, then the glass - with an energy-saving coating. And if the color of reflection remains the same, then this is an imitation of such a product, a fake.
