They're high performing and energy efficient, made from strong, polyester powder-coated frames for a long-lasting finish that won’t corrode. We can also configure the windows in any way you choose, to best suit your home. With more than 200 colours – including dual colours – and a selection of decorative glass, fixtures and glazing options available, Anglian double glazed aluminium windows are truly bespoke.

Each aluminium casement window is individually made with your choice of colour, configuration and glass.

Our stylish double glazed aluminium casement windows are powder coated for durability and come with a 10 year guarantee, sealed units are guaranteed for 15 years. They exceed building regulations and come with a B energy-efficiency rating as standard.

As well as being secure and energy efficient, they're incredibly effective at noise reduction, and cutting down sounds from outside. Each aluminium window has three aluminium window weather seals to prevent draughts and leaks and keep the windows water and air tight.

They’ll also guide you through deciding the best configuration for each room and selecting other features like decorative bars and glass designs that will make your windows unique.
