Engineered for simplicity, Winco’s slider windows are thermally broken and are available as sliding, fixed and unitized systems. These products come in two frame depth options — 3 ¼ or 4 inches — and 1/16 inch wall thickness mainframe and sash. Often used in applications such as schools, hospitals and condominiums, our sliding windows feature a steel self-lubricating roller and a US25D sweep lock at meeting rail and extruded auto jamb lock for smooth operation. With a four-sided fin seal weather strip, a dual glazing option and optional integral blinds, you get premium performance at a competitive price.
