EWT 70
EWT 70 Door Window Systems, which provides high heat resistance against different climatic conditions in all seasons, offers high comfort to users in all building types with its 3-chamber structure and polyamide heat barrier, as well as two alternative profile structures with 1.5 mm and 2.0 mm wall thickness. EWT 70 system with 70 mm profile depth also allows the use of glass up to 58 mm.
Designed with Euro-Groove channels, the system is suitable for inward or outward opening, double opening and transom window openings required for windows and doors. The air and water tightness criteria of the system, which also allows the use of PVC compatible opening mechanisms, were determined as a result of performance tests carried out in internationally accredited test laboratories.
