Aluminium windows: more glass, less frame

Why aluminium

Strength is the whole point

Aluminium is structurally stronger than uPVC or timber, which means the frame can be much thinner and still hold a large, heavy sealed unit.

That difference shows up as daylight. In the same opening, an aluminium frame gives you a noticeably bigger area of glass than a plastic one — which is why it dominates on extensions, garden rooms and anywhere with a view worth framing.

It also holds a crisp, square edge that suits modern architecture, and it will span heights and widths that other materials struggle with. Gable and apex glazing is a job aluminium does particularly well.

• Slim sightlines and large panes
• Powder-coated finish that won’t need repainting
• Ideal for extensions, gables and garden rooms
• Matching windows, doors and bifolds in one finish
