Are aluminium windows better than uPVC?

Whether aluminium windows are better than uPVC depends on your priorities:

Aluminium offers slimmer frames, a modern look and exceptional durability
uPVC is usually cheaper and still provide strong insulation

Aluminium is often chosen for contemporary homes or large glazed areas, while uPVC suits tighter budgets.

Are aluminium windows more expensive than uPVC?

Aluminium windows generally cost more upfront than uPVC due to material strength, manufacturing processes and aesthetics.

However, aluminium frames are long-lasting and low maintenance, which can make them cost-effective over time.

Tip: Our cost of aluminium windows vs uPVC guide helps you weigh up the pros, cons and prices of both.

What are the disadvantages of aluminium windows?

While aluminium windows are strong and stylish, potential downsides include:

Higher initial cost
Can feel colder to the touch (although modern thermal breaks reduce heat loss)
Fewer budget options compared to uPVC

That said, choosing high-quality windows helps improve energy efficiency, which could save you money in the long run.

What is the lifespan of aluminium windows?

Aluminium windows are extremely durable and can last 30–45 years or more when properly installed and maintained.

They resist warping, rust and weather damage, making them well suited to UK conditions.

Tip: Our how to stop condensation on windows guide has lots more tips and solutions.

If your windows are draughty, misted or inefficient, upgrading to modern aluminium double glazing can improve insulation, security and kerb appeal.
