How to choose the right Origin window

Both versions of our Origin aluminium windows come with the same high specification for their profiles, locking systems, handles and components. Where they differ is their styling and sightlines.

Where your project demands slimmer windows, choose the OW-70 as this comes with the slimmer lines, a flush casement styling outside, and a regular stepped vent inside. The OW-80 range offers is thicker for bolder styles with a 91mm sightline, also coming in larger window sizes, lower U-Values and more window design options.

Origin aluminium windows come in a substantial choice of colours but choose the standard range of colours and benefit from some of the fastest window lead times available.

Grey 7015 Matt, Grey 7016 Matt, Grey 7021 Matt, Black 9005 Matt, Metallic 9007 Matt, White 9910 Matt, White 9910 Gloss and Dual colour White 9910 Gloss/Grey 7016 Matt are all available in just a few days.

  • Highest specification multi-point locking systems
  • Colour-matched window handles
