Origin Aluminium Windows

Our aluminium casement windows are available in two Origin systems, Slimline (OW-70) and Premium (OW-80), so you can choose the style and performance that best suits your home.

Slimline (OW-70) – with ultra-slim 65 mm sightlines, this option maximises glass and natural light for a contemporary look. Its sleek, external flush design is perfect for modern homes or extensions where you want a minimalist finish and uninterrupted views.

Premium (OW-80) – offers internal and external flush styling, a deeper frame (91 mm), and the option to include Aerogel insulation, which can improve thermal performance by up to 67% and achieve U-values as low as 0.9 W/m²K. The stronger profile allows for larger window sizes, ideal for feature glazing such as gables or bays.

Both systems are PAS 24 and Secured by Design certified, fitted with high-security multi-point locking, and tested for long-term reliability.

French aluminium windows open outwards without a central mullion, offering an unobstructed opening that maximises ventilation and natural light. They’re ideal for upper floors, kitchens, or areas where clear views and easy egress access are important.

Gable windows follow the roofline to create dramatic glazing for vaulted ceilings, extensions, and open-plan spaces.

They fill rooms with light while enhancing the architecture of your home, a striking design feature that combines form and function.

Using the same smooth-running engineering as Origin’s award-winning doors, bi-fold windows fold neatly to one side to completely open up your space.

Perfect for kitchen serving hatches, garden rooms, or entertaining spaces, they bring flexibility, air, and light into your home.

Aluminium bay windows project outwards to add space and dimension to your property.

Their angled design enhances both light and views while maintaining excellent energy efficiency and security. They’re available in multiple configurations to complement both modern and period homes.

When you want uninterrupted views and large expanses of glass, picture windows are the perfect solution. Fixed and frameless in appearance, they create a seamless connection between inside and out, ideal for feature walls, stairwells, and rooms where natural light takes centre stage.

For oversized installations, our experienced fitting team uses specialist lifting equipment to ensure every pane is positioned safely and precisely, giving you a smooth, efficient installation from start to finish.
