ARS-72
The ARS-72 is a high-end window designed for projects that prioritise design, natural light and efficiency, while maintaining a high level of technical performance.
With an 85 mm sash-to-frame section, one of the slimmest on the casement window market, it maximises the glazed area and enhances natural light ingress, delivering a light and contemporary aesthetic.
Its configuration, with a 34 mm polyamide thermal break, central EPDM gasket and cellular polystyrene foams, ensures a high level of watertightness and thermal insulation, achieving a Uf value of 1.5 W/m²K and positioning it among the most efficient windows on the market.
It incorporates options such as concealed hardware, micro-ventilation and a frame with concealed drainage, improving both water performance and overall aesthetics. In addition, its compatibility with the ARS platform enables standardised fabrication, optimised stock management and reduced costs.
