In-House vs Outsourced uPVC Fabrication

Some 'manufacturers' outsource the actual fabrication. Here's why in-house making matters.

The difference

Look for this

  • In-house: one team controls quality end to end
  • In-house: build precisely to your openings
  • In-house: accountability stays in one place
  • In-house: service from the makers themselves

Be cautious of

  • Outsourced: quality depends on an outside factory
  • Outsourced: responsibility split across parties
  • Outsourced: harder to guarantee the result
  • Outsourced: service can fall between parties

Questions

Frequently asked

What's the difference between in-house and outsourced fabrication?

In-house means one team controls quality and builds to your openings end to end; outsourced means quality depends on an outside factory and accountability splits.

Does Glassterr fabricate in-house?

Yes — cutting, reinforcing, welding, glazing, and fitting all happen at our Pannimadai works.

Why does in-house matter?

It keeps quality control and accountability in one place, rather than depending on an outside factory.
