EWT 70
Door - Window SystemsEWT 70 Door and Window Systems are engineered to provide exceptional heat resistance throughout all seasons, effectively countering diverse climatic conditions. This system is characterized by a 3-chamber design and a polyamide thermal barrier, and it offers users high comfort in various types of buildings. Additionally, the system features both 1.5 mm and 2 mm profile thickness option. The EWT 70 system, which has 70 mm frame profile depth, provides applying glazings up to 58 mm.
The system is intelligently designed with Euro-Groove channels, that makes the system suitable for various opening configurations including inward or outward openings, tilt and turn openings, and bottom hung Windows. The air and water tightness of the system, which also permits the use of PVC-compatible opening mechanisms, has been established through performance tests conducted in internationally accredited test laboratories.
