uPVC Supplier vs Manufacturer: What's the Difference

'Supplier' and 'manufacturer' aren't the same thing. Here's the difference and why it matters.

The difference

Look for this

  • Manufacturer: makes the windows themselves
  • Manufacturer: factory-direct, no resale margin
  • Manufacturer: controls quality in-house
  • Manufacturer: accountable end to end

Be cautious of

  • Pure supplier: may resell others' windows
  • Pure supplier: adds a margin as go-between
  • Pure supplier: quality depends on the maker
  • Pure supplier: accountability can split

Questions

Frequently asked

What's the difference between a uPVC supplier and manufacturer?

A manufacturer makes the windows themselves, factory-direct with no resale margin; a pure supplier may resell others' windows, adding a margin as a go-between.

Is Glassterr a supplier or manufacturer?

A manufacturer — we supply what we fabricate in-house at our Pannimadai works.

Why does it matter?

Buying from the manufacturer removes the resale margin and keeps quality and accountability in one place.
