Why it matters

Look for this

  • More rigidity and resistance to warping
  • Better support for hardware and glass
  • A sturdier frame over the years
  • Generally a marker of a quality profile

Questions

Frequently asked

Why does uPVC profile wall thickness matter?

Thicker walls mean a more rigid, robust frame that resists warping and supports hardware and glass better; very thin walls flex over time.

Is thicker always better?

Generally sturdier, yes, but it's one marker among several — chambers, reinforcement, and formulation matter alongside it.

How do I check it?

Ask the maker about the profile's wall thickness and reinforcement. Quality profiles maintain a sound thickness rather than thinning to cut cost.
