Questions

Frequently asked

Why does uPVC wall thickness matter?

It determines the frame's rigidity. Sound thickness resists warping and supports hardware and glass; thin walls flex and warp over time.

Can I see the wall thickness?

Not easily once it's a finished window — which is why cheap profile sometimes thins it. Ask the maker and choose a quality branded system.

Is thin-walled profile a false economy?

Usually yes — it shows up later as flex and warping, costing more than it saved.
