Windows open to horizontal form

Kawneer Co. Inc.'s OptiQ Ultra Thermal Window AA5450 Series is available in a horizontal sliding configuration. The AA5450 Series has a polyamide thermal break that increases thermal performance and is enhanced by accommodating 1-inch double-pane or 1 1/2-inch triple-pane insulating glass. The alignment of the insulating glass unit with the thermal break allows the window to maintain thermal continuity.
