Why more chambers help

Look for this

  • Trapped air improves thermal insulation
  • Better sound dampening
  • Internal walls stiffen the frame
  • Generally a marker of a better profile

Questions

Frequently asked

What are chambers in a uPVC profile?

Hollow sealed sections inside the profile, separated by internal walls. More chambers trap more air, improving insulation and rigidity.

Are more chambers better?

Generally they improve insulation and sound dampening, but the right number depends on the window's size and job.

Do chambers affect noise?

Yes — trapped air in each chamber dampens sound, contributing to a quieter window.
