Aluminium vs uPVC Doors: An Honest Comparison

Where each material genuinely wins, and where the difference is mostly aesthetic.

The choice between aluminium and uPVC doors is usually framed as premium versus budget. That is too crude — they solve different problems.

Here is how we compare them on survey, using the criteria that actually change how the door performs and how it feels to use.

Where aluminium wins

Aluminium is the right answer when:

The opening is wide and you want minimal frame and maximum glass.
You want a specific powder-coated colour, or different colours inside and out.
The door is heavily used or exposed, and rigidity matters.
You are matching existing aluminium glazing elsewhere on the property.

Where uPVC wins

uPVC is the better buy when:

Budget is the deciding factor and the opening is a standard size.
Thermal performance per pound spent is the priority.
The door is in a sheltered position where the frame is barely seen.

Where the difference is smaller than the sales pitch

Both materials are effectively maintenance-free beyond cleaning and lubrication. Both can be specified with modern multipoint locking. Both are available in convincing woodgrain or coloured finishes.

Security comes from the lock, cylinder and glazing method far more than from the frame material.

We'll price aluminium and uPVC for the same door so the comparison is real, not theoretical.

Frequently asked questions

Is aluminium always more expensive?

On a like-for-like size, generally yes. The gap is smallest on large openings where uPVC needs reinforcement anyway.

Which is warmer?

Well-specified examples of both perform well. Compare the quoted U-values rather than assuming by material.

Can I mix materials on one house?

Yes, and plenty of homeowners do — aluminium on a large rear opening, uPVC elsewhere. We'll show you how it will look before ordering.
