Aluminium or PVC exterior doors — how to choose the right material

The material affects a door's strength, thermal performance, maintenance and the overall appearance of your home.

As with windows, the material of an exterior door affects its durability, thermal insulation and appearance. Aluminium and PVC each offer distinct benefits — the right choice depends on your home and priorities.

Aluminium exterior doors

Advantages

High resistance to mechanical stress and attempted forced entry.
Long-term resistance to changing weather conditions.
A thermally broken construction can provide strong thermal insulation.
A broad choice of colours, textures and decorative details.

What to consider

Construction quality varies considerably — doors without a thermal break can feel colder.
A heavier construction requires high-quality, durable hinges.

Best suited to:

homes where security, durability and broad design freedom are the main priorities.

PVC exterior doors

Good thermal insulation without complex additional solutions.
Easy care and low maintenance requirements.
A comparatively lighter construction.
A good balance of price and quality.

Mechanical strength is generally lower than with aluminium doors.
Size, colour and sun exposure can affect profile stability, so the construction must be specified correctly.

homes where insulation, easy maintenance and a sensible budget matter most.

How should you choose?

If maximum durability, security and design flexibility are your priorities, a thermally broken aluminium door is a strong choice. If good insulation, easy maintenance and a sensible price matter most, a well-made PVC door is a practical solution.

Is quality more important than material?

Yes — construction quality, seals, hardware and installation influence the final result at least as much as the material itself. A high-quality PVC door can outperform a poor aluminium door in thermal insulation, and vice versa.
