What’s the difference between Tiaso AZ 78, J AZ 40 and FIRST 100 partitions?

The difference between these three lines is the concept:

• AZ 78mm, 78mm thick reference partition.
  This is the standard office partition on the French market.
• J-AZ 40mm, 40mm-thick glass partition.
  It’s a minimalist, edge-to-edge, single-glazed partition.
• FIRST 100mm, 100m-thick premium partition.
  The premium partition from TIASO.
