Condensation on aluminium windows is usually a spec issue, not a faulty window. It forms when a cold surface — the frame or the glass — meets warm, humid air, and in the UAE that cold surface is almost always the result of air conditioning cooling the frame or glass faster than the room around it. The fix is usually about the window's specification, not a repair.
Why Condensation Forms on Aluminium Windows
Condensation forms when a cold indoor-facing surface meets warm, humid air. In a UAE home, that cold surface is typically the frame or glass, cooled by air conditioning, meeting warmer, humid air inside the room.
Standard, non-thermal-break aluminium conducts heat and cold readily, so the frame's interior surface temperature drops close to the AC-cooled air temperature. That's what triggers condensation on the frame itself, even when the glass looks fine.
Thermal Break Windows and Why They Help
A thermal break window has an insulating barrier built into the aluminium profile, separating the interior and exterior sections of the frame. That barrier keeps the interior surface warmer than it would be in a standard aluminium frame, which reduces condensation risk significantly.
Single-glazed glass also cools faster than double-glazed glass, so upgrading to double glazing reduces condensation on the glass pane itself, not just on the frame.
Other Ways to Reduce Condensation
Setting the AC unusually cold widens the temperature gap between the indoor surface and the room air, making condensation more likely regardless of window specification. Keeping the thermostat at a more moderate setting reduces that gap.
Condensation is not automatically a sign of a faulty installation — it's a predictable outcome of a window's frame and glass spec meeting AC-driven temperature differences. The fix is usually a spec change, such as a thermal break frame or double glazing, rather than a warranty issue.
