64T System
64T System is an aluminium joinery system offering wide openings, designed for projects requiring energy efficiency and maximum durability with 24 mm heat barrier and high wall thickness.
Başak Aluminium 64T System is a modern aluminum profile system with a 64 mm frame width and 72 mm sash width, allowing for wide glass applications. With a wall thickness of 1.8–2 mm and a 24 mm thermal break, it ensures high thermal insulation and energy efficiency.
Equipped with polyamide insulators and EPDM gaskets, the system provides long-lasting sealing and insulation. It supports glass thicknesses between 10–34 mm and features a central gasket for water and dust blocking, along with a secure air and water drainage system. The Euro-standard accessory channel enables quick installation and easy access to compatible hardware. Corner cleat connections and custom profile options deliver both aesthetic and secure solutions for architectural projects.
