System Overview
The RUIT 55i is an entry-level thermally broken aluminum window and door system engineered for energy-efficient commercial buildings and residential developments. Featuring a 55mm frame depth and 64.1mm sash depth, it incorporates 26.2mm multi-chamber polyamide thermal break strips that achieve a thermal resistance rating of R0 = 0.58 m²°C/W under severe climate conditions from -45°C to +50°C. The system supports glazing infills from 4mm to 34mm with perimeter EPDM seals, providing effective acoustic insulation up to 40 dB. Key advantages include an economical balance of thermal performance and affordability, versatile configuration for tilt-turn windows and entrance doors, high wind load resistance, and durable powder-coated profile surfaces.
