Origin OW-80 Premium Windows
Overview
The Origin OW-80 is Origin's premium aluminium window. Its sashes sit flush with the frame both inside and out, giving the crisp, timber-like finish that suits period homes and high-end new builds alike. With Origin's Aerogel insulation upgrade it reaches U-values as low as 0.8 W/m²K.

Origin OW-80: frequently asked questions
What does "flush" mean?
The opening sash sits level with the outer frame rather than standing proud of it, so the window looks like one smooth surface, much like a traditional timber casement.
Is the Aerogel upgrade worth it?
It is worth considering for larger glazed areas, colder elevations or projects aiming for high energy performance. We can price it alongside the standard specification.
Does it suit a period home?
Yes. The flush finish and Georgian or Soho bar options make it a strong choice for Victorian, Edwardian and Georgian properties. Listed buildings and some conservation areas have extra rules, which we check at survey.
