Learn how to easily adjust PVC windows for winter and summer — improve the seal, reduce heat loss and keep your home comfortable all year round.
Did you know that many modern PVC windows have a hidden feature designed to adapt to Lithuania's changing seasons? It's seasonal adjustment — a simple mechanism that lets you change how firmly the window gasket is pressed.
Done twice a year, this small adjustment is an effective way to improve home comfort, increase energy efficiency and even extend the life of your windows. In this guide we explain the principle behind winter and summer modes, how to adjust the windows yourself and when it's time to call a professional.
The goal of seasonal adjustment is to make your windows work smarter — not harder — in both cold and warm weather.
Goal in winter: maximum heat retention. Setting windows to "winter mode" increases the sash's pressure against the rubber gaskets.
Benefits: a better seal, lower heat loss, lower heating bills and no drafts.
Goal in summer: better airflow and less load. Switching to "summer mode" reduces gasket pressure.
Benefits: easier operation, better micro-ventilation, less strain on gaskets and a longer service life.
Adjusting windows is simple — it takes just a few minutes:
Find the cams — open the window and look at the side of the sash.
Check the marking — the closer the marker is to the gasket, the tighter the seal.
Winter mode — turn the cams towards the room to increase pressure.
Summer mode — turn the cams towards the outside to decrease pressure.
Check tightness — use the sheet-of-paper test.
Contact a specialist if:
The window frame is deformed or damaged.
Even with winter mode set, you still feel a draft.
The handle, hinges or lock are sticking.
The window is out of adjustment and operates with difficulty.
This simple twice-a-year procedure helps keep your home comfortable and reduces energy costs.
Winter and summer window adjustment isn't just about convenience — it's a smart way to save energy and money. A few turns can ensure a warm, sealed home in winter and comfortable ventilation in summer.
