FAQ

What you need to take into account during the operation of windows?

Answer: The best way how to ensure long life of your windows or doors – at least once a year to clean their opening part (mechanism), which usually collects dust and other dirt. After cleaning, the fitting system needs to be greased or oiled, if it is obvious, that this is necessary. Particular attention should be paid to the fact of cleaning, if in a room where the window is placed building or repair works are performed.

Why does the condensation appear on the window and the window sweats?

Answer: Condensation appears due to differences in temperature and humidity in the areas where the window is and type of space ventilation. Typically, customer complaints on the steamy window if the window is foggy – condensation appears on the the inside part of the glass in the the room, it is due to the significant difference in humidity and temperature (this factor may appear briefly, for example in the kitchen, where there is intensive cooking and a large amount of steam, which appears as a result of insufficient ventilation.). If glass becomes misted inside the Double-glazed window, it probably is damaged, and should be replaced as soon as possible.

Why the space along the convergence of the window opening and window frame emanates cold?

Answer: There are two major reasons. One reason may be poor installation of constructions, during which certain conditions were not followed, for example – sufficient density of installation was not achieved. The second reason – the temperature of the glass surface of the window is lower than temperature in the room, resulting in air exchange near the surface of the glass (indoor air cools, and tends to bottom), which has the effect of wind. This is normal. The lower is the coefficient of thermal conductivity of the window used, the less the effect.

How does the coefficient of thermal conductivity changes with the choice of different types of double-glazed windows and profile construction systems?

Answer: Coefficient of thermal conductivity depends on the glass used in the double-glazed window (selective or simple) configuration of double-glazed window, and its gas filling. Coefficient of thermal conductivity of the profile system is based on the number of cameras and gaskets of the profile. What needs to be taken into account, is that the use of cheap double-glazed windows in combination with the profiles of the highest quality, or vice versa, does not guarantee the reduction of the coefficient of thermal conductivity.

What is the best system of profiles in terms of energy efficiency and sound insulation for the windows in the house?

Answer: Coefficient of thermal conductivity of the windows in the the Uw SI system refers to the amount of heat in watts, which is calculated on the area of 1m2 of glass per hour, provided that the difference between external and internal temperature is 10 ° C. The lower the Uw value, the higher the energy savings.

We offer systems of windows with the following Uw:

1. 1.3 (W) – System of profiles KBE70 with 2 glasses and filling with argon gas;
2. 1.0 (W) – System of profiles KBE70 with 3 glasses and filling with argon gas;
3. 0,8 (W) – Profile system KBE88 + with 3 glasses and filling with argon gas.

Which double-glazed windows to choose?

Answer: Depends on the requirements for energy efficiency, required to provide, and the type of application.

Do you need built-in ventilation system in the design of windows or of doors?

Answer: The ventilation system is needed. It, at least, would provide the minimum necessary air exchange in the the room (of course, it depends on the room square and the size of the window).

How to protect yourself by making the glass unbreakable?

Answer: It is possible to order the stroke resistant windows, which are covered with a special coating (film), shock resistance of glass increases with the number of coatings. Coverage does not always provide the crushing of glass from the impact, but provides stability (glass does not fall apart, and remains in the space provided for, preventing unauthorized entry in the premises).

How should the edge of the window opening before the assembly of the window look?

Answer: During the measurement of windows, our specialist will conduct inspection of the opening, and will inform you of the necessary preparatory work, if necessary. The quality of installation of the window depends on preparation of the opening.

What if there are difficulties when opening the window?

Answer: These difficulties in opening a window or doors’ wings (the friction of the frame at the opening) is explainable with structural deformationof the construction, in which the window is built-in (subsidence). Another case – too frequent manipulation of the window or door (as a result of friction fitting of the construction wears out, this is normal). If you purchased the window from the manufacturer, call the manufacturer and arrange the visit of the master, who will work on adjusting.
