The optimal solution in opening aluminum systems for quality-to-price ratio. A modern, comprehensive opening system with strong advantages in performance, aesthetics, and design. It offers excellent performance coefficients in all aspects, even in the most adverse climatic conditions, and ensures maximum security.
Its wide range of construction options, combined with its technical properties, makes it the best match for the SV-3400 Slim Slide sliding system. This combination is the ideal choice for replacements of old systems, meeting all required specifications.
For a minimal aesthetic and enhanced security, the option of a hidden sash is available, offering external uniformity and reducing the visible frame surface.
