Slim, strong frames that let in more glass and more light — a genuinely different look to uPVC, at a genuinely different price point.
Aluminium's main advantage over uPVC is strength-to-frame-width — because the material is so much stronger, the frames can be far slimmer while still holding large panes of glass securely. That means more visible glass, a more contemporary look, and it's a common choice for larger windows, bifold doors, or extensions where a slim sightline actually matters to the design.
Worth knowing upfront: aluminium typically costs more than uPVC for a like-for-like window. Where it earns that back is on larger openings, where uPVC's bulkier frames would otherwise eat into your glass area significantly.
