Aluminium Windows Condensation: Causes and Solutions

Condensation is a common issue that many homeowners experience, and aluminium windows are not exempt from this. While aluminium windows are known for their durability and sleek design, condensation can still occur, causing frustration and potential damage to the windows and surrounding areas. In this blog post, we will explore the causes of aluminium windows condensation and discuss possible solutions to address this problem effectively.

1. What causes condensation on aluminium windows?

Condensation occurs when warm, moist air comes into contact with a cold surface. In the case of aluminium windows, the temperature difference between the warm indoor air and the cold window frame can lead to condensation forming on the surface. While it is normal for some condensation to occur, excessive moisture can cause issues if left unaddressed.

Factors that may contribute to condensation on aluminium windows include:

• Poor ventilation: Insufficient ventilation in the rooms can lead to stagnant air, which increases the likelihood of condensation forming on the windows.

• High humidity levels: Activities such as cooking, showering, and even breathing can release moisture into the air, raising the humidity levels in your home and potentially leading to condensation.

• Draughts: Air leakage around windows can cause temperature variations, leading to condensation forming on the colder surfaces.

2. Solutions to reduce condensation on aluminium windows:

• Improve ventilation: Ensuring adequate airflow in your home is crucial in minimizing condensation. Open windows regularly, install extractor fans in areas prone to moisture, and consider utilizing dehumidifiers if humidity levels remain high.

• Use trickle vents: Many modern aluminium windows come with built-in trickle vents. These vents allow controlled airflow while maintaining the desired energy efficiency level, reducing the chances of condensation.

• Check for draughts: Seal any gaps and cracks around your windows to prevent cold air from entering the room, thus helping to maintain a consistent temperature and reducing the occurrence of condensation.

• Consider secondary glazing: Installing secondary glazing on your aluminium windows can significantly reduce condensation. This additional layer of insulation creates a barrier between the warm interior air and the cold window surface, minimizing condensation formation.

• Proper insulation: Ensure proper insulation of your windows, including sealing any gaps between the frames and the walls. Insulation helps to maintain a more consistent temperature inside, reducing the likelihood of condensation.

3. Maintenance tips:

Regularly check the condition of your aluminium windows to ensure they are adequately maintained. Keep the frames clean and check for any signs of deterioration or damage that may contribute to condensation. Regular maintenance, such as cleaning the windows and checking for proper drainage, will help prevent condensation issues.

In conclusion, while condensation can occur on aluminium windows, proper ventilation, insulation, and maintenance can significantly reduce the likelihood and impact of this issue. If condensation persists despite implementing these solutions, it may be worth consulting a professional window supplier or installer for further advice tailored to your specific situation.
