How do uPVC and aluminium compare on cost? Here's an honest explanation of what actually drives the difference.
For your home, we'd explain what drives your quote and where you can sensibly economise.
Aluminium window frames are strong and slim, which lets them carry large panes with thin sightlines. But aluminium conducts heat readily, so an aluminium frame transmits more heat than uPVC unless it has a thermal break.
uPVC frames are multi-chambered — the hollow chambers trap air, which slows heat transfer. That makes uPVC naturally insulating without needing a thermal break.
Rather than quote a misleading rate, the honest answer is that both are priced by specification — the glazing, hardware, and sizes drive far more of the number than the frame material alone. We quote your actual openings.
It depends entirely on specification — glazing, hardware, and sizes drive more of the cost than the frame material. A high-spec uPVC window can cost more than a basic aluminium one. We quote your actual openings rather than a flat rate.
Glazing choice, size, hardware, and reinforcement — usually more than the frame material itself.
Because it misleads — it hides the specification, which is where the real cost sits. We'd rather quote your real job honestly.
