Double glazing is a fantastic investment for homes in the UK, offering insulation, energy efficiency, and noise reduction. However, condensation inside double glazing can cause frustration for many homeowners. Not only does it obstruct your view, but it may also indicate a more significant issue with your windows. In this guide, we’ll explore the causes of condensation inside double glazing and discuss proven solutions to resolve the problem effectively.
What Causes Condensation Inside Double Glazing?
Condensation inside double glazing occurs when moisture becomes trapped between the two panes of glass. This isn’t the same as external condensation (on the inside or outside of the window), which is usually harmless. Condensation inside the unit typically points to a failure in the window’s seal or the breakdown of the desiccant material within the spacer bar.
Here are some common causes:
- Failed Seals: Over time, the seals around the edge of the glass can degrade due to weather exposure, age, or poor installation, allowing moisture to seep inside.
- Temperature Changes: Fluctuations in temperature can cause the seals to expand and contract, weakening them and leading to leaks.
- Desiccant Saturation: The spacer bar contains a desiccant material designed to absorb moisture. If this becomes saturated, it can no longer prevent condensation.
- Low-Quality Windows: Budget or poorly manufactured double glazing may lack durability, making them prone to seal failure and condensation issues.
Why Is It Important to Address Condensation Inside Double Glazing?
Ignoring condensation inside double glazing can lead to several problems, including:
- Reduced Energy Efficiency: Moisture between the panes compromises the insulating properties of your windows, leading to higher energy bills.
- Obstructed Views: Foggy windows can spoil the appearance of your home and reduce natural light.
- Potential for Mould Growth: Trapped moisture may encourage mould or mildew around the window frame, which can affect indoor air quality.
- Decreased Property Value: Persistent condensation can signal poor window performance, potentially putting off future buyers.
Proven Solutions for Condensation Inside Double Glazing
If you’re dealing with condensation inside your double glazing, there are several options available to restore your windows to their original clarity and performance.
1. Repair the Window Unit
In some cases, a professional can remove the moisture, clean the interior of the panes, and reseal the unit. While this is a cost-effective option, it may only be a temporary solution if the seals are significantly damaged.
2. Replace the Double Glazing Unit
If the seal failure is extensive, it may be necessary to replace the affected double glazing unit. This involves keeping the existing frame but installing a new glass unit, which is more affordable than replacing the entire window.
3. Upgrade to Modern Double Glazing
If your windows are old or made from low-quality materials, consider upgrading to modern double glazing. Newer units often come with improved sealing technology and better insulation, reducing the risk of condensation in the future.
4. Check Ventilation in Your Home
While this doesn’t solve existing condensation inside the panes, ensuring good ventilation can help prevent further issues. Use extractor fans in kitchens and bathrooms, and consider adding trickle vents to your windows to improve airflow.
5. Invest in Window Maintenance
Regular maintenance, such as inspecting and resealing windows, can extend the life of your double glazing and prevent condensation problems.
How to Prevent Condensation Inside Double Glazing in the Future
Prevention is always better than cure. Here are some tips to keep your double glazing in top condition:
- Choose high-quality windows with a reliable warranty when installing or upgrading your double glazing.
- Ensure professional installation to avoid premature seal failures.
- Conduct annual inspections to check for cracks, seal damage, or other signs of wear.
- Keep indoor humidity levels in check by using a dehumidifier or improving ventilation in problem areas.
