Choosing the width

Look for this

  • Narrower series — standard casement windows
  • Wider series — large sliders and big spans
  • Match the width to the opening size and type
  • Wider isn't universally better — match to the job

Questions

Frequently asked

What's the difference between 60mm and 80mm uPVC profile?

Roughly the frame depth — wider (80mm) is generally stronger for larger and sliding systems, narrower (60mm) suits standard casement windows.

Is 80mm better than 60mm?

Not universally — it's about matching the width to the opening. Wider suits large spans; narrower suits standard windows.

Who decides the profile width?

The maker, matched to each opening's size and type, when measuring and fabricating.
