The most common problems with aluminium windows are condensation on poorly specified frames, a higher upfront cost than uPVC, and finish damage from low-grade powder coating. Most issues come from the specification or fitting rather than the metal, and thermally broken frames avoid the worst of them.
Why do some aluminium windows get condensation?
Aluminium conducts heat, so a frame without a thermal break stays cold and attracts moisture from warm indoor air. A thermally broken frame has an insulating barrier between inner and outer sections, which largely removes the problem.
What other problems should you check for?
- Fading, chalking or peeling from a poor powder coat
- Blocked drainage slots causing water to pool
- Worn seals and hardware after many years of use
- Scratches or dents, since aluminium can mark in a way that is hard to hide on dark colours
- Poor fitting, such as gaps left around the frame
Are aluminium windows worth the extra outlay?
Often yes for slim sightlines, strength and long life, but the benefit depends on how long you plan to stay and how much the slimmer frame matters to you.
The best protection is a clear written specification covering thermal break, coating and glazing. Wednesfield Trade Windows is a family-run, Certass registered firm that fits aluminium windows.
