Condensation Concerns? Look Beyond Your Windows and Doors!

Writer's picture: Tina MillerTina Miller

Condensation. It's a familiar sight, especially during the colder months, and often the first thing homeowners blame is their windows – particularly if they've recently invested in new, energy-efficient, thermally broken aluminium windows and doors. But before you point the finger, it's crucial to look beyond the glass and understand the real reasons why condensation forms. Your thermally broken aluminium windows are likely not the culprit.


The Science Behind the Droplets:

Condensation is a natural phenomenon. It's simply water vapour in the air transforming into liquid water when it encounters a cold surface. Think of a chilled drink on a summer's day – the condensation you see forming on the outside of the glass is the same process in action.


Why Condensation Appears on Windows (and Elsewhere):

Windows, being a relatively cool surface, are often where condensation becomes most visible. Warm, moist air inside your home, generated by everyday activities like cooking, showering, and even breathing, comes into contact with the cooler window glass, and the water vapour condenses. But remember, it's not the window's fault; it's just the first cold surface the moist air encounters.


Why Thermally Broken Aluminium Windows Are Unlikely to Blame:

Thermally broken aluminium windows are actually designed to minimise condensation. The "thermal break" – an insulating layer within the frame – separates the cold exterior from the warm interior. This significantly reduces heat transfer, keeping the window surface warmer and making condensation less likely than with older, less efficient windows.


The Real Reasons for Condensation (and Where to Look):

So, if your windows aren't the problem, what is? Here are the most common culprits, and they often lie beyond the windows themselves:

  • Excess Humidity: Too much moisture in the air is the primary cause of condensation. This can stem from poor ventilation, hidden leaks, or daily activities like cooking and showering. Check for damp patches on walls or ceilings, which could indicate a leak.

  • Inadequate Ventilation: If moist air isn't being effectively removed from your home, it will eventually condense on the coldest available surfaces. Are you using extractor fans in the kitchen and bathroom? Are rooms properly ventilated?

  • Temperature Discrepancies: A significant difference in temperature between the inside and outside of your home increases the likelihood of condensation. This is more pronounced in winter when it's cold outside and warm inside.

  • Cold Spots in Your Home: Condensation can form on any cold surface, not just windows. Check walls, mirrors, tiles, and even furniture, especially in corners or areas with poor air circulation. These cold spots might indicate insulation issues or thermal bridging.


Taking Control of Condensation (Beyond the Windows):

  • Boost Ventilation:  Prioritise good ventilation. Open windows regularly (even briefly), use extractor fans diligently, and consider a whole-house ventilation system if necessary.

  • Manage Humidity:  Address sources of excess moisture, such as leaky pipes or damp patches. A dehumidifier can also be a valuable tool.

  • Improve Air Circulation:  Ensure air can flow freely around your rooms. Avoid placing furniture directly against walls or windows, as this can trap moist air.

  • Insulation Check:  Poor insulation can create cold spots, increasing condensation. Consider upgrading insulation in walls, lofts, and around windows and doors.

  • Wipe it Away:  If condensation does occur, wipe it down promptly to prevent dampness and mould.


Focus on the Positive:

Your thermally broken aluminium windows are working hard to keep your home warm and energy-efficient. The condensation you see is a sign of excess moisture in your home's environment, not a fault with the windows themselves. By addressing the underlying issues of humidity and ventilation, you can effectively manage condensation and enjoy the benefits of your high-performance windows.
