YKK AP's YPI 1500 is an interior secondary access panel window system designed for new and retrofit installations where enhanced thermal, sound, or privacy performance are critical to occupant comfort. The YPI 1500 can be integrated into most new and retrofit Storefront, Window Wall and Curtain Wall systems with little disruption to building occupants. When existing windows are weather-tight, and ventilation unnecessary, YKK AP interior accessory windows will improve thermal performance, reduce sound infiltration, and add privacy and security with optional between-glass Venetian blinds.
The YPI 1500 interior access panel features minimal frame depth to fit within existing window frame openings, side-hinged access doors with custodial locks, integrated 5/8" or 1" between-glass Venetian blinds available in 16 colors, slip-clutch blind tilt control knob, lift out and pivot access panels, concealed blinds with tilt control, vent and frame multi-point locks, increased privacy and occupant comfort and retrofit installation with low maintenance.
