Description
Highly Thermally Insulated Aluminium Door System with Advanced Anti-Bi-Metal Technology
The Aluron AS 75 aluminium door system is a modern three-chamber solution designed for the construction of thermally insulated entrance doors in residential, commercial and public buildings. Combining excellent thermal performance, structural stability and contemporary aesthetics, the system provides a reliable solution for modern architectural projects.
A key feature of the system is the use of innovative anti-bi-metal separators, which significantly reduce profile deformation caused by large temperature differences between interior and exterior environments. This ensures long-term dimensional stability, smooth operation and exceptional durability throughout the product lifecycle.
The system supports large door dimensions and heavy glazing units while maintaining outstanding thermal insulation values. With Ud values from 0.93 W/m²K, AS 75 contributes to energy-efficient building envelopes and increased indoor comfort throughout the year.
In addition to its thermal performance, the system offers enhanced protection through RC2 and RC3 burglar resistance classifications. High levels of watertightness, air permeability and acoustic insulation make the system suitable for projects where comfort, security and reliability are essential requirements.
