The RÄUM brand signifies luxury and ultimate style, giving you confidence all RÄUM products are designed to offer superior aesthetics, operate smoothly, and are also built to last.


As such, RÄUM is positioned at the high-end of the door market, where there is high demand for systems which embrace innovation, luxury and performance.

Our aluminium window range offers a stylish and sleek window that adds a modern feel to any project. With slim frames yet an exceptionally strong composition, our windows are rigorously tested to offer high performance and beautiful aesthetics.


With industry-leading levels of insulation and security, these windows are made of the highest quality aluminium to suit all specifications. From contemporary residential projects to high-end commercial developments, we have the right aluminium windows for any function and use.


The aluminium we use in our windows is at least two and half time stronger than uPVC for an exceptional window and can hold larger glass panes with narrower frames. This allows for a unique look and windows that let in more light. With a rebated frame for added weatherproofing and a multi-chambered profile, draughts and cold spots are a problem of the past.

With a 20 year Guarantee and super-fast turnaround, these market-leading British manufactured windows are as practical as they are beautiful.


Remarkable design and expert manufacturing techniques are built into Origin-Global’s DNA.


Smart and clean in appearance, the sash sits neatly inside the window frame, creating an industry-first internal and external flush casement.


​With no overlapping frames, often synonymous with windows, the flush casement comes together to create a truly timeless finish. All that remains is a sleek shadow line where the sash meets the frame.


​The clean finish of the Origin Window therefore provides unbeatable versatility that lends itself perfectly to any property type, from traditional townhouses, new builds and apartments through to projects under strict planning regulations in conservation areas.


​Aluminium’s innate strength allows for incomparably slim sightlines without compromising on security. With the edge of the frame as little as 50mm from the glass, it means less window and more light can be achieved.
