Double glazed windows are known for their ability to reduce heat loss, minimize noise pollution, and increase the overall energy efficiency of a home. However, like any other component of a building, they are not immune to wear and tear, and issues such as draughts can arise over time. If you’re experiencing draughty double glazed windows, it’s essential to understand the potential causes and how to address them effectively. In this article, we will delve into the world of double glazing, exploring why draughts might be occurring and what you can do to rectify the situation.
Understanding Double Glazed Windows
Before diving into the reasons behind draughty double glazed windows, it’s crucial to have a basic understanding of how they work. Double glazed windows consist of two panes of glass separated by a gap, which can be filled with air or a gas like argon. This design significantly reduces heat transfer between the inside and outside of the window, making homes warmer in the winter and cooler in the summer. The gap between the panes also acts as an insulator, helping to minimize noise pollution from outside.
The Importance of Sealing in Double Glazing
One of the critical components of double glazed windows is the seal around the edges of the glass panes. This seal is what keeps the air or gas between the panes from escaping and prevents external air from entering the gap. A well-maintained seal is essential for the window to function correctly, ensuring that it remains energy efficient and free from draughts. Over time, however, the seal can deteriorate due to various factors, leading to a decrease in the window’s performance.
Factors Affecting the Seal
Several factors can affect the integrity of the seal in double glazed windows. Age, for instance, is a significant factor, as the sealant materials degrade over time. Weather conditions, such as extreme temperatures, heavy rainfall, and exposure to sunlight, can also impact the seal’s effectiveness. Furthermore, physical stress on the window, like vibrations from traffic or construction, can cause the seal to weaken.
Causes of Draughty Double Glazed Windows
If your double glazed windows are draughty, it’s likely due to one of several common issues. Identifying the cause is the first step in rectifying the problem.
Failed or Failing Seals
As mentioned earlier, the seal is a critical component of double glazed windows. If the seal fails or is failing, it can allow air to escape from or enter the gap between the panes, leading to draughts. A failed seal can be identified by the presence of condensation or mist between the panes, which indicates that moisture is entering the gap.
Frame Issues
The frame of the window can also contribute to draughts if it is not properly sealed or if it has become damaged over time. Gaps around the frame can allow cold air to enter and warm air to escape, making the room feel draughty. This issue can often be resolved by re-sealing the frame or, in more severe cases, replacing it entirely.
Installation Problems
Sometimes, the issue with draughty double glazed windows can be traced back to the installation process. If the windows were not installed correctly, with proper sealing and alignment, it could lead to gaps and weaknesses in the window’s structure, facilitating draughts. In such cases, reinstallation or adjustments by a professional might be necessary.
Solutions to Draughty Double Glazed Windows
Fortunately, there are several solutions available to address draughty double glazed windows, ranging from simple DIY fixes to more complex repairs that may require professional assistance.
DIY Solutions
For minor issues, such as small gaps around the window frame, DIY sealing solutions can be effective. Using a good quality sealant, like silicone or polyurethane foam, can help to fill gaps and prevent draughts. It’s essential, however, to ensure that the sealant is compatible with the window materials to avoid causing damage.
Professional Repairs
In cases where the issue is more significant, such as a failed seal or damaged frame, professional repair or replacement may be necessary. A qualified window repair technician can assess the situation and provide the appropriate solution, whether it’s re-sealing the window, replacing the frame, or installing new double glazed units.
