The UltraVue Lift Slide Window system features low profile carriages to create big views on large windows. Lift slide windows provide maximum view/maximum value allowing larger openings with fewer panels and more glass. Very large panels glide easily and quietly, with no friction on the bottom track or weather-seal, while providing security and weatherability. Panels can stop at any position for easy access and ventilation. For a wall design solution that gives a large view and avoids door sill issues, use a lift slide window instead of a door. Suitable for wood, aluminum clad wood, all metal or PVC sashes. LEED credits can be earned under Indoor Environmental Quality for Natural Ventilation, Daylighting, and Views.
