Common Problems with Aluminium Windows
Although Aluminium windows are generally durable and low-maintenance, they can experience a few common problems over time. Here are some of the most common problems with Aluminium windows:
Condensation & Corrosion
Condensation occurs when warm, moist air comes into contact with a surface that is cooler than the dew point of the air, causing water vapour to turn into liquid water. The factors influencing condensation on aluminium frames include temperature differentials, humidity levels, and the thermal conductivity of the material.
In general, both powder-coated and anodized aluminium provide a protective layer that can resist corrosion, but they may have different characteristics:
Powder-Coated Aluminum:
| 1. Powder coating is a type of finish that provides a durable and decorative layer to aluminium surfaces. 2. While powder coating can enhance the corrosion resistance of aluminium, the effectiveness depends on the quality of the coating and the preparation of the surface before coating. 3. If the coating is damaged or if the surface preparation is inadequate, it may compromise the protection against corrosion and, potentially, against condensation. |
Anodized Aluminium:
| 1. Anodizing is an electrochemical process that thickens the natural oxide layer on the aluminium surface, creating a durable and corrosion-resistant finish. 2. Anodized aluminium tends to be more resistant to corrosion than powder-coated aluminium. 3. The anodized layer is integral to the aluminium, making it less susceptible to chipping or peeling. |
Both powder-coated and anodized aluminium frames offer corrosion resistance, but anodized aluminum generally provides a higher level of protection. The choice between them may depend on factors such as aesthetics, cost, and specific environmental conditions. It’s important to note that no finish is completely immune to corrosion, and proper maintenance can extend the lifespan of both types of finishes. Regular cleaning and addressing any damage promptly can help prevent corrosion issues.
Drafts:
Poor installation or damage to window seals can lead to drafts around Aluminium windows, which can reduce energy efficiency and increase heating and cooling costs. Proper installation and regular maintenance can help to prevent drafts.
Fading or Discolouration
Exposure to sunlight can cause Aluminium window frames to fade or discolour over time, which can affect their appearance. Choosing a high-quality finish or regularly cleaning and refinishing the frames can help to prevent this issue.
Warping or Bending
Extreme temperature changes or improper installation can cause Aluminium window frames to warp or bend, affecting their functionality and appearance. Proper installation and regular maintenance can help to prevent warping or bending.
Heat or Cold Thermal Transfer
Aluminium is a good conductor of heat, which means that Aluminium windows can transfer heat from the interior of a building to the exterior, or vice versa, more readily than other materials. This can affect your home’s temperature and energy consumption. However, the degree of impact depends on factors such as the window type, exposure to direct sunlight, installation location, and the local climate.
Air infiltration & Noise transmission
If Aluminium windows are not properly installed or sealed, they may allow air to leak in or out of a building, or may not provide as much noise reduction, which can affect indoor air quality, and comfort.
Overall, Aluminium windows are a reliable and durable option for many homeowners. To address these problems, it’s important to work with a reputable brands & supplier or installer who can provide high-quality, energy-efficient Aluminium windows and ensure that they are properly installed and sealed. Additionally, regular maintenance and upkeep can help to prevent or mitigate many of these issues.
