The Basak Aluminium 58T System combines a 58 mm frame width with a 66 mm sash width, suiting wide openings. A wall thickness of 1.8 to 2 mm provides extra structural durability, while an 18 mm polyamide thermal barrier delivers a thermal transmittance of Uf 2.96 W per square meter K for windows and doors.
The accessory channel is compatible with Euro-standard hardware, simplifying installation and supply. EPDM gaskets ensure long-term sealing across glass thicknesses from 4 to 34 mm, with a central gasket blocking water and dust. A secure drainage system and corner-cleat joints support reliable performance and clean corner detailing.
