Aluminium Bay Windows
Custom-made, bespoke bay windows.
Our aluminium bay windows provide a versatile solution for a wide range of projects, offering flexibility when it comes to style, specification and performance.
Manufactured using premium Cortizo aluminium profiles, they combine slim sightlines with strength, durability and excellent thermal efficiency. The slim profile allows for larger areas of glazing, helping to maximise natural light while maintaining a contemporary appearance.
Available in five standard colourways, with bespoke RAL colours also available, our aluminium bay windows can be specified to complement a variety of project requirements.
