EWT 55
Door - Window SystemsEWT 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. Designed with a 55 mm case and 65 mm sash depth, the system provides price optimization, especially in large projects, by offering sash options suitable for the use of equally sized slats.
Designed with Euro-Groove channels and compatible with all opening mechanisms, EWT 55 is suitable for all openings such as inward or outward opening, double opening and transom window. PVC compatible opening mechanisms can also be used with the system. Performance tests carried out in internationally accredited institutions played an important role in determining the durability criteria of the system.
