How to adjust plastic windows
A window (window opening) or a stained - glass window is an architectural detail of construction specially conceived in the building structure: an opening in the wall, which serves for the entry of light into the room and ventilation. The location, number and size of windows play an important role in building design. Windows are the main (up to 50%) source of heat loss in buildings.
A double - glazed window is a translucent construction for construction purposes of two or more glasses fastened (glued) to each other along a contour using distance frames and sealants. The purpose of a double-glazed window as a replacement for ordinary glass is to increase the window's heat transfer resistance, since air and some other gases do not allow heat to pass through well.
Earlier, with the onset of winter, people pasted their wooden windows with paper stripes and plugged the cracks with foam rubber. With the installation of a plastic window in the room, you can forget about these worries. But often the master installers, having quickly completed their work, forget to tell the happy owners of the new window about two important things, which we will tell you about later in our article.
Firstly, all moving parts of the hardware need regular lubrication. Perform the procedure at least once a year, pouring ordinary engine oil. Secondly, with the change of seasons, the windows must be switched to summer and winter, respectively. So that the gum does not deform and recover after a tight vestibule in the winter, it is enough in the summer not to turn the handles to the end by 15-30 degrees. At the same time, an influx of fresh air through micro-slots is ensured. Please note that minus any grease is dust sticking and curtains getting dirty!
Secondly, adjust the special eccentrics (trunnions) of the double-glazed window. Almost all modern designs are equipped with the adjustment option. To check if the hardware is switched to another mode, just look at the special eccentrics (trunnions) located on the side surface of the sash.
If they have holes for a hexagon or an asterisk screwdriver, as well as if the eccentric is oval, then such accessories will surely be transferred to summer or winter mode. But it is better to clarify the ability to switch before installing windows.
To switch the window mode, simply use the appropriate tool to turn all the trunnions on the leaf (the larger the window is, the larger the number) in the desired position.
If the sash is constantly in winter mode, this leads to an additional load on the sealing gum and it wears out faster. The window pressing force is easy to verify. Hold the leaf on a regular sheet of paper: if you can easily remove it, the window is in summer mode.
