The Premium Window is elite in design possibilities and performance. With an industry-unique internal and external flush casement, its design is influenced by traditional 19th Century timber windows, but is executed with the flawless finish that our aluminium provides, as well as being manufactured for modern day living.

Offering huge maximum sizes (up to 7m² for a single fixed frame), its design opportunities are limitless. It has been originally designed for the Contemporary aesthetic, but should you want to make a statement, it can be in the Soho design. This would include bars rather than true divides.

The OW-80 has been engineered to offer optimal thermal efficiency. Additionally, it’s the only window system that can be upgraded to include space age technology, Aerogel.
