The Truth About Condensation and Aluminium Windows and Doors

Condensation on aluminium doors and windows is a common occurrence that many homeowners may overlook. However, understanding the causes and implications of condensation is crucial for maintaining the longevity and efficiency of these fixtures.

What Causes Condensation?

Condensation is the process by which water vapour in the air transforms into liquid water on a surface. Factors that contribute to condensation include high humidity levels, low temperatures, and poor ventilation.

When warm, moist air comes into contact with a cooler surface, such as a window, the air cools down and is unable to hold as much moisture, leading to the formation of water droplets. This is why condensation often forms on windows during colder months when indoor heating is in use.

Properties of Aluminium Windows and Doors

Aluminium doors and aluminium windows are constructed using a combination of aluminium frames and glass panels. The frames are typically made from extruded aluminium sections that are cut and welded together to form the desired shape and size.

The glass panels are then fitted into the frames using rubber gaskets or sealants to create a watertight seal. While aluminium windows and doors are known for their durability and strength, they can be susceptible to condensation if not properly insulated.

How to Stop Condensation on Aluminium Window Frames

There are a few steps you can take to prevent condensation from forming. Firstly, ensure that your home is properly ventilated by opening windows or using exhaust fans in areas like the kitchen and bathroom. This will help to reduce moisture levels in the air.

Additionally, you can use a dehumidifier to remove excess moisture from the air. Another option is to use a silicone-based sealant around the edges of your windows to prevent warm air from escaping and condensing on the cold aluminium frames.

It is also important to ensure that the windows and doors are properly insulated and sealed to minimise the transfer of heat and moisture between the inside and outside the building.
As well as this, using double or triple glazing can help reduce condensation by creating a barrier between the warm interior air and the cold exterior air. If the condensation is severe, it is always worth considering getting your windows replaced.

Are Slimline Aluminium Windows Affected Differently?

Slimline Aluminium Windows behave differently from normal aluminium windows when it comes to condensation. Here are a few of the key condensation points to note when going with Slimline-designed windows:

Frame Surface Area

Slimline aluminium windows have a less visible frame and more glass. Since there’s less aluminium exposed, there’s less surface area to get cold and collect condensation on the inside. However, the remaining aluminium can still get cold quickly.

Thermal Break

Modern slimline aluminium windows almost always include a thermal break, so they resist condensation better than older or standard non-broken aluminium frames.

Glass-to-frame Ratio

Slimline designs usually mean more glass and less frame. Since double or triple-glazed glass with low-E coatings insulates better than bare aluminium, the overall window surface may stay warmer inside, reducing condensation compared to bulkier aluminium sections.

Slimline aluminium windows often have less risk of visible condensation on the frame compared to traditional bulky aluminium ones, mainly because they expose less aluminium and usually use modern thermal breaks. However, both types will still be more prone to condensation than uPVC or timber windows if they don’t include thermal breaks or if indoor humidity is high.

Aluminium Windows and Condensation: What’s the truth

In conclusion, it is crucial to prioritise the proper care and maintenance of aluminium windows and doors to prevent condensation. Regular cleaning, sealing, and ventilation can help maintain the integrity of these fixtures and minimise the risk of moisture build-up.

By taking proactive steps to preserve the condition of aluminium windows and doors, homeowners can ensure a comfortable and healthy living environment for years to come.

Even though slimline aluminium windows produce less visible condensation, it’s still important to take the proper care to ensure they last effectively for the long term.
