PVC windows with double glazing, known for their high thermal and sound insulation, play a crucial role in maintaining your home’s thermal comfort, especially during the cold season. But did you know that proper winter adjustment can significantly improve their efficiency? Follow this step-by-step guide to optimize your windows for warmth and lower energy bills.

Why Is Winter Window Adjustment Necessary?

Double-glazed windows come with adjustable hardware systems that allow switching between summer and winter modes. The winter mode enhances airtightness, reducing heat loss, while the summer mode allows better ventilation.

Switch to winter mode if:

• You feel cold drafts near the windows.
• You notice frequent condensation on the glass surface.
• Windows become difficult to open or close.

Simple Steps for Proper Window Adjustment

1. Identify the Metal Locking Pin
Look for the rotating element with a hexagonal slot on the window’s edge. It controls the pressure of the sealing gasket.

2. Adjust the Pressure with a Size 4 Hex Key

• Winter: Turn the locking pin clockwise to increase pressure. The seals will be tighter, preventing heat loss.
• Summer: Turn the pin counterclockwise to reduce pressure, allowing better ventilation.

3. Test the Airtightness
Insert a sheet of paper between the window frame and sash, then close the window:

• If the paper slides out easily, the pressure is insufficient for winter.
• If the paper is tightly gripped, the adjustment is correct.

4. Lubricate Hinges and Hardware
Check if the hinges need lubrication for smooth operation. Use a special hardware oil.

Внимание: Риски чрезмерной регулировки

Frequent window adjustment can cause:

• Premature wear of rubber gaskets.
• Damage to hardware components.

Manufacturers recommend adjusting only when necessary and performing regular window maintenance to avoid these issues.

Tips for Proper Window Maintenance

• Clean windows with non-abrasive solutions at least twice a year.
• Regularly check the condition of gaskets and hardware.
• Test window functionality by moving the handle into all positions.

Conclusion

Proper window adjustment for the cold season is a simple operation that significantly improves thermal comfort and saves energy. If you encounter difficulties or notice advanced wear, consult a specialist for a detailed inspection.
