uPVC vs Aluminium Windows: Which Is Right for Your Home?

New windows make your home warmer, quieter and more secure — and instantly smarter from the street. The two most popular materials are uPVC and aluminium. Both are excellent; they just suit different budgets and styles. Here’s how to decide.

uPVC windows — best for value and warmth

uPVC is the UK’s most popular window material for good reason. It’s affordable, extremely well insulated and virtually maintenance-free. Modern uPVC windows come in a wide range of colours and woodgrain finishes, so you’re no longer limited to white. If you want the best balance of cost, energy efficiency and choice, uPVC is hard to beat. See our uPVC windows.

Best for: most homes, energy savings, tighter budgets.

Aluminium windows — best for style and slim frames

Aluminium is a premium choice prized for its strength. Because the material is so rigid, aluminium frames can be much slimmer than uPVC — meaning more glass, more light and a sleek, contemporary look. It’s incredibly durable, powder-coated in almost any colour and ideal for larger openings and modern extensions. See our aluminium windows.

Best for: contemporary homes, large windows, maximum daylight, longest lifespan.

Quick comparison

Which should you choose?

• Want the best value and warmth? Choose uPVC.
• Want slim frames, more glass and a modern look? Choose aluminium.

Both are far more efficient than older single or early double glazing, and both will cut your heating bills and outside noise.
