Buy from the people who make it

There is a real difference between ordering windows from a listings marketplace and ordering them from the factory that fabricates them. Here is the case for factory-direct.

A marketplace / aggregator

  • Your enquiry is passed to whichever fabricator is available
  • A layer of margin sits between you and the maker
  • Hard to visit the place your windows are actually built
  • Questions travel through an intermediary

Glassterr, factory-direct

  • Your windows are made in our own Pannimadai unit
  • No dealer markup — you deal with the manufacturer
  • Walk into the factory and see the work before you commit
  • Answers come straight from the people building it
