Tips for maintenance, upkeep, proper ventilation and cleaning of different types of windows


If the walls of the windows have not yet been plastered – do not remove the pads between the masonry and frame – they ensure flawless functioning of the wings of the window and they should not be removed. The pads should remain in the plaster.

After completing the installation, please clean the bottom frame using a vacuum cleaner with a peaked nozzle. Any metal shavings left over from the installation can cause the appearance of rust.

After installing the windows you can remove the protective film (tape). In any further repairs in order to protect the windows against contamination, you should use the foils recommended by the manufacturer of the windows.


Quality hardware has been installed on your purchased windows. Beware, that the handle of the window to be always in a vertical position (up / down) or horizontally.

Leaving the handle in an intermediate position can cause a wrong opening (with the exception of cases, in which is mounted a special casing, providing a slot for ventilation). It may happen, that in the upper opening position of the sash the same can be rotated on a vertical axis. Do not be afraid! The so-called “scissors” of hardware retain the wing at the top. Move the handle up (position of the upper opening), close the window and then turn the handle in a horizontal position (open along a vertical axis).

Sash, according to the type of the fitting should be closed always as follows:

  • Closed – handle vertically downwards;
  • fully open – handle horizontally;
  • ventilation – the handle straight up – only when the wing has a combined hardware.

For proper functioning of windows` moving parts (hardware), they should be lubricated with oil (acid-free) at least twice a year.

Never, however, lubricate the following items:

  • camps sliding hardware;
  • backs of the hinges and fittings for the double plane opening;

Do not hang anything (except the blinds provided for the purpose, with a certain weight) on the window casement – this may lead to difficulty closing, creep and other problems.
