Is an aluminium window better than uPVC?

Aluminium is better than uPVC for slim frames, large glazed areas, longevity and finish options, but uPVC is better for budget and simple replacements. Neither is better on every measure, so the right choice depends on the look you want and what you will spend.

When is aluminium the better choice?

  • You want slim frames and more glass
  • The opening is large and needs a strong frame
  • You prefer a modern or steel-look style
  • You want a very long lifespan with low maintenance

When is uPVC the better choice?

uPVC suits tighter budgets and standard replacements, and its frame naturally insulates. Modern uPVC also comes in woodgrain and coloured finishes, so the look gap has narrowed.

Is aluminium more energy efficient?

Not automatically. Window energy performance depends on the frame, glazing and spacer. A thermally broken aluminium window with quality glazing can achieve an A rating, so compare ratings for the full window.

Ratings and guarantees give a fairer comparison than the frame material alone. Jake surveys every job himself, and JMF Windows Oxford fits aluminium windows with a 10-year guarantee and Certass registration.
