How to Stop Condensation on Windows
Condensation on windows is a common issue faced by many homeowners, especially those with single-glazed windows. Understanding the root causes and implementing effective solutions can significantly reduce this problem. We'll explore how Extraglaze secondary glazing can help mitigate window condensation and provide practical tips for addressing the underlying causes.
Understanding Condensation
Condensation occurs when moist air comes into contact with cold surfaces, such as windows. This process results in water droplets forming on the surface, which can lead to issues like mould growth and damage to wooden window frames. The key to reducing condensation lies in managing both the temperature of window surfaces and the humidity levels within your home.
The Role of Extraglaze Secondary Glazing
Extraglaze secondary glazing offers an effective solution for reducing condensation on windows. By creating a warmer internal surface and an insulating air gap, this system helps to minimise the temperature difference that causes condensation. However, it's important to note that while Extraglaze can significantly reduce window condensation, it does not address the sources of moisture within a home, which in some homes can be severe.

Benefits of Extraglaze Secondary Glazing
- Warmer Inner Glazing Surfaces: The additional layer of glazing increases the temperature of the window surface, reducing the likelihood of condensation forming there.
- Warmer Room Surfaces: when the windows are insulated the room can maintain a warmer temperature, so there will be fewer or no cold surfaces elsewhere in the room, where condensation might otherwise take hold.
- Reduced Circulation and draughts: Circulation (unless driven by a fan) is air being drawn from a hot part of the room to a colder part. In rooms with uninsulated windows you experience circulation as a cold draught, usually at your feet. Condensation on the window glass comes back just as fast as you can wipe it up. In a room with secondary glazing air is moving around much more slowly and unable to “deliver” nearly as much moisture.
- Insulating Air Gap: The air gap acts as a thermal barrier, further preventing heat loss and maintaining a consistent internal temperature.
- Easy Installation: Extraglaze panels are made to measure and ready to install, making them a convenient option for homeowners.
Practical Steps to Reduce Condensation
While Extraglaze secondary glazing is a valuable tool, addressing condensation requires a holistic approach. Here are some practical steps homeowners can take:
Improve Ventilation
- Open Windows: Regularly open windows to allow fresh air to circulate and reduce humidity levels.
- Use Extractor Fans: Install extractor fans in kitchens and bathrooms to remove moisture-laden air during cooking and showering.
Reduce Indoor Humidity Sources
- Dry Laundry Outside: Whenever possible, dry clothes outside or use a tumble dryer which extract to outside to prevent excess moisture from entering the home.
- Cover Pots While Cooking: Use lids to minimise steam release and reduce humidity in the kitchen.
Use Tools to Remove Moisture
- Window Vacs: Invest in a window vacuum to quickly remove condensation from glass surfaces, preventing water damage and mould growth. Once removed in this way it has left the room forever so it can’t come back again.
Consider Extraglaze for Insulation
- Evaluate Windows: Assess your windows to determine if Extraglaze secondary glazing should be part of your solution for reducing condensation and improving energy efficiency.
A Comprehensive Approach to Managing Condensation
Condensation on windows can be a persistent problem, but with the right strategies, it can be managed effectively. Extraglaze secondary glazing offers a reliable way to reduce window condensation by creating a warmer internal surface and an insulating air gap. By combining this with improved ventilation, reduced sources of humidity, and moisture-removal tools, homeowners can significantly mitigate condensation issues.
