ARS-82
The ARS-82 is the most premium solution within the ARS range, combining outstanding thermal performance, minimalist design, and optimized production efficiency in a high value-added system. Its slim visible sash-frame section of just 85 mm maximizes natural light entry while delivering a clean, modern, and elegant aesthetic.
With a thermal transmittance value of Uf 1.2 W/m²K, the ARS-82 ensures excellent insulation performance even under demanding climatic conditions, helping to meet the strictest energy efficiency requirements. In its Passivhaus-certified configuration, it achieves a Uf value of 0.978 W/m²K, making it an ideal solution for Nearly Zero-Energy Buildings (NZEB) and projects developed under the highest international energy-efficiency standards.
The system also integrates advanced comfort and functionality features such as micro-ventilation, concealed drainage, and hidden hardware, enhancing both usability and aesthetics.
Its full compatibility with the ARS platform enables process standardization, component sharing, and workshop optimization, reducing operational costs and stock requirements.
