Plastic windows are equipped with a mechanism that allows you to adjust the tightness of the flaps to the PVC profile. The trunnion is switched in order to optimize airing in the summer and to exclude heat loss during frost. Before you adjust the plastic windows for winter mode, you need to deal with the accessories for tuning, to study the position of the regulators. Neglecting seasonal adjustment, users reduce the life of the design.

Seasonality in the operation of plastic windows
The need for adjustment arises when the window pulls cold and heat quickly evaporates from the room. Another option is that the sealant is worn out, and there is a need to press the sash tightly to eliminate the draft. Accessories installed on window structures guarantee 3 operating modes of euro-windows:
- The neutral or standard position of the regulator - an eccentric or trunnion - ensures optimal contact of the sash with the frame. Suction and blowing through the gum does not occur due to moderate preload of the sealant.
- Winter mode involves a more dense attraction of the glass to the profile. Compression of the cord reliably blocks the movement of air through the wings on both sides.
- Summer regulations provide minimal impact on the sealing tape, allows the movement of air masses in the micro-ventilation of the room.
Regulatory fittings are located on the end faces of the sash. Information on the possibility of adjustment is located on the trunnion surface: holes for a hexagon, a screwdriver, an asterisk key will indicate the validity of setting up a window. The operating mode, providing long-term use of the window sash, is summer. It can be used constantly if residents do not feel discomfort, and dust does not penetrate into the room.
Winter is frosty in most regions of the country., and switch the mode with the onset of cold weather still have to. It is better to do this in late autumn. The reverse translation of the plastic window mode from winter to summer is carried out in early spring.
It is not recommended to use a strong clip in the heat: when heated, the profile expands, which can lead to damage to the fittings.
Switching the double-glazed window to winter mode
The primary adjustment of plastic windows for summer or winter mode is performed by the wizard when installing the window unit. Which regulation will be chosen depends only on the specialist himself: this may turn out to be a neutral setting. To determine the degree of pressing of the sash, there are 2 ways: using a sheet of paper laid between the frame and the folding glass, and visual inspection of the clips.
In the first case, the opened canvas with a bookmark needs to be closed and try to pull out the sheet. If you succeed - the regulations are summer, no - winter.
Another way is to inspect the pins, they have a mark on them. When a bar or dot is directed toward the room, the clip is strong, and vice versa. The oval retainer does not have marks: the mode confirms its position - vertical means summer, horizontal indicates winter. To configure the standard regulation, you need to turn the latch into a diagonal state. How to put a double-glazed window in winter mode:
- Find the trunnion on the leaf, wipe the profile with a cloth and apply grease to the fittings. The number of regulators is determined by the size of the window - on ordinary canvases put 3 eccentrics on the handle side.Large-area flaps are additionally equipped with locks in the hinge area, above and below.
- Consider the setting marks on the controls. Adjustment of the plastic window fittings for winter mode is performed by turning each of the existing pins to the desired position. If the latch is recessed into the sash, it must be pulled out, rearranged and deepened again. A label directed towards the room towards the rubber band means strong pulling of the glass unit. The oval pin must be installed in a horizontal position.
- Check the sash for tight fit by removing the paper sheet.
It is not recommended to adjust the window in winter - heat will leave the room, the sealant will freeze. It is better to switch the summer mode to winter mode in the fall, with the temperature being set at 5 ... 10 ºС.
Consequences of failure to switch to winter
Some manufacturers of PVC windows recommend using the summer mode of operation year-round, as the most sparing for the sealant and accessories. If you do not put the trunnions in the winter position, problems can occur during frost. The consequences of deviating from the rules:
- drafts and heat loss;
- deterioration of the microclimate of the room, increased humidity;
- formation of condensation and mold on the windows.
Seasonal transitions are accompanied by lubrication of accessories, this prolongs the trouble-free operation of the mechanisms.
Adjustments allow timely response to malfunctions and promptly eliminate them.
