E50 is one of the most modern thermal insulation systems ETEM. Designed for medium and large openings, E50 combines the trends in modern architecture with the needs arising from the strict standards for energy conservation.
In designing E50 parameters such as the growing need for a brighter building interior, the ease in operating the window, safety, energy conservation and protection from severe weather conditions are taken into account.
E50 is a system designed to cover a wide range of requirements, in both existing and new buildings, that have medium size and large openings. The system is rigid and capable to operate under heavy loads resulting from the large glass surfaces, while it is subtle enough to be used for smaller windows.
With 50 mm sash width and innovative design, E50 is a robust system with excellent thermal insulation and water tightness characteristics rendering the system an ideal choice for the majority of residential and commercial applications.
