uPVC Quality Inspection & Checks

Every window we make is checked before it leaves the factory. Here's what we inspect.

What we check

Look for this

  • Frame dimensions match the measured opening
  • Welded corners are strong and sealed
  • Reinforcement is correctly fitted
  • Hardware operates smoothly and locks properly
  • Glazing is secure and sealed
  • Finish is clean and unmarked

Questions

Frequently asked

How does Glassterr check window quality?

We inspect dimensions, welded corners, reinforcement, hardware operation, glazing, and finish before each window leaves the factory.

Why does quality inspection matter?

Catching issues at the factory means they're fixed before the window reaches your home.

Who is accountable for quality?

The same in-house team that builds the windows — nothing is passed to a third party.
