Adjusting windows seasonally keeps your home warm in winter and cool in summer, reduces energy use and extends window lifespan. A simple adjustment twice a year ensures comfort and proper sealing.
Did you know that many modern PVC windows have a hidden feature that lets you adapt them to the changing seasons in Poland? It is called seasonal adjustment – a simple mechanism that changes the pressure of the window seal.
This small adjustment, carried out twice a year, is an effective way to improve home comfort, increase energy efficiency and even extend the lifespan of your windows. In this guide we explain the principle behind winter and summer modes, how to adjust windows yourself, and when to call a professional.
1. The 'Two Seasons' Principle: Why Adjust Your Windows?
The purpose of seasonal adjustment is to make your windows work intelligently in both cold and warm weather.
In winter: the priority is keeping warmth inside and avoiding draughts. Setting windows to 'winter mode' increases the pressure of the sash against the rubber frame seals.
Benefits: better sealing, less heat loss, lower heating bills.
In summer: a tight seal is not necessary. Switching to 'summer mode' reduces the pressure on the seals.
Benefits: better micro-ventilation, easier opening, less stress on seals, longer lifespan.
2. DIY Guide: How to Adjust Windows Seasonally?
Window adjustment is straightforward and takes just a few minutes:
Find the adjustment cams – open the window and look at the side of the sash.
Understand the markings – the position of the marker shows the pressure level. The closer to the seal, the tighter it is.
Winter mode – using a hex key, turn the cam towards the interior.
Summer mode – turn the cam towards the exterior.
Check the seal – insert a piece of paper between the window and frame. If it is difficult to pull out, the seal is good.
3. When Is Professional Help Needed?
Contact a specialist if:
The window frame is deformed or damaged.
You still feel draughts even after setting winter mode.
The handle or hinges are broken or stiff.
The window is severely misaligned.
Conclusion
Regular seasonal window adjustment is a simple but highly effective way to keep your home warm in winter and comfortably cool in summer. Just a few steps, twice a year, can save on heating costs, extend window lifespan and ensure maximum sealing.
If draughts persist after adjustment, the cause may be worn window seals — a separate issue that requires seal replacement or resealing.
