An Investment for Years: Confidence and Security with Aluminum

The economical DA-70N aluminum joinery series is dedicated to investors who expect reliable solutions with good thermal insulation and enhanced resistance to intensive use.

The solid aluminum profiles used in DA-70N windows ensure high structural stability, durability in everyday operation, and optimal resistance to environmental factors, making them a recommended choice even for more demanding conditions. Carefully selected materials, high-quality hardware, and a wide range of functional accessories ensure that the system maintains its full aesthetic appeal and technical performance for many years.

DA-70N Windows: Modernity Within Reach

This versatile aluminum system is designed for both newly built single-family homes and larger developments, as well as renovation projects in various types of buildings.

The innovative DA-70N window series offers numerous design possibilities, including the option of a concealed sash or an outward-opening variant, significantly increasing design flexibility. The system performs perfectly in panoramic glazing and shopfront applications, and matching external doors (based on profiles from the same series) help achieve complete aesthetic consistency throughout the entire project.
