OW-80 vs OW-70 Fixed Frames

Origin Fixed Frames are available in either our OW-80 or OW-70 range. The key difference between the two ranges is the width of the sightline, with OW-70 offering the thinnest sightline for more natural light and views. However, OW-80 can be manufactured in a larger size, up to 7sqm, whereas the OW-70 can be manufactured up to 4.8sqm. Both widows offer a guarantee of up to 20 years and a range of over 150 RAL colours and popular colours available on a faster lead time.

Frame existing doors or windows

If you’re looking to utilise the space surrounding your existing doors or windows then Origin’s Fixed Frame Windows offers the ideal solution. Adding fixed frames to either side of your doors - whether they’re Bi-fold Doors, French Doors or Sliding Doors - or underneath casement windows creates a much brighter space with better views. And, with our flush casement, your fixed frames will look extremely elegant.

Elegant and bespoke

With a minimum size of 0.06sqm and a maximum size of 7sqm, there’s very little that our fixed frame windows can’t accommodate.

From size to colour, our windows are entirely bespoke, allowing you create the exact window you want.

Energy efficient

Achieving a U-Value of 0.9W/m2K and energy rating of A++ when combined with Aerogel insulation, Origin Fixed Frames are able to offer thermal efficiency that’s out of this world. The polyamide thermal break found in the aluminium frames helps to keep your home warm in winter and cool in summer, consequently helping to lower your energy bills.
