Seal the deal: Simple steps to weatherproof your windows

Anyone who has ever dealt with leaky windows knows how bothersome winter draughts can be. Damage or worn-out seals are sometimes the culprits behind these issues. Over time, they can lose elasticity, leading to small but significant gaps. Regardless of how well the window is constructed, these components greatly influence the effectiveness of thermal insulation.

Another often overlooked cause of heat loss is gaps between the window frame and the wall. Small, invisible spaces can result in uncontrolled heat loss.

Sealing windows should begin with identifying where heat is escaping. The best way to detect leaks is the candle test. Move a lit candle along the window frame, and the spots where the flame flickers will indicate leaks. You can also do this by moving your hand along the frame. If you feel a draught, the window is leaky at that spot.

How should you seal PVC windows? Various tools and materials are available today for effective window sealing. One of the most popular is sealing tape. These easy-to-apply products can be found in most hardware shops. Their advantage is the ease of installation and quick effect; you simply need to apply them along the window frame.

How do you seal windows with expanding foam? Expanding foam is perfect for filling larger gaps. Its major advantage is that it expands significantly in a short time, effectively securing empty spaces. However, be mindful of the amount used, as excessive foam can lead to unsightly bulges.

One of the steps is also checking the adjustment of windows and hinges. For modern windows, there is the option to adjust the pressure, which allows you to tailor their tightness depending on the season. Proper tightening of hinges and adjustments can lead to noticeable improvements in window tightness.

During window sealing, do not forget a common cause of leaks – old seals. Replacing them is a straightforward procedure that greatly enhances insulating efficiency.

Many people make the mistake of completely sealing windows, forgetting the need for ventilation. Therefore, it’s advisable to avoid completely blocking airflow, as this can lead to damp and mould in rooms.

Well-sealed windows result in considerable savings on heating costs. Eliminating cold draughts allows for more efficient heat management in rooms, leading to lower bills. Moreover, improving thermal insulation also increases thermal comfort inside the home.

All of these window sealing measures are relatively simple and can be done independently, without the need for professionals. In winter, when every bit of warmth counts, it’s worthwhile to check and secure windows to enjoy a cosy home throughout the season.
