EWT 55 is a thermally insulated window and door system that provides high resistance to different climatic conditions with its three-chamber structure. It offers high comfort to users, especially when used in residential and public projects in temperate climate regions such as the Aegean and Mediterranean.

Although the system has 20 mm PVC or Polyamide heat barrier options, two different profile structures are available with 1.5 mm and 2.0 mm wall thickness.
