About Series 540 Single/Double Hung Window with Solar Control Louvers

The Sol-A-Trol Series 540 is a high-performance commercial window system that combines the traditional utility of single or double hung operation with integrated solar control jalousie louvers. Engineered to meet the demanding structural requirements of the Florida market, this hybrid system offers a versatile dual-functioning solution. It allows architects and developers to specify a single unit that balances controlled fresh air intake via adjustable louvers with standard vertical sash operation, making it ideal for high-occupancy commercial and institutional environments.
