High-performance casement window and balcony system.

With 74 mm deep frames, a hidden drainage system and a thermal transmittance of 0.9 W/m2K, it is an exceptional system to ensure compliance with the most demanding regulations in any climate zone. Its insulation is also reinforced by polyamide foams and polyamide tubular chambers.

Its minimalist aesthetics with a visible chassis of only 23 mm and its reduced central node give great visual elegance to the system, with straight and coplanar lines towards the outside.

Available in versions with visible and hidden leaves.
