Economical, low-maintenance, weather-tight window built for harsher climates; complements many architectural styles. Integral nailing fin surrounds the perimeter of the frame and helps make installations weather tight; for new construction or replacement. Top sash is stationary; bottom sash slides open vertically. Factory-painted white finish is attractive and durable. Block and tackle balance system supports the vertical operation of the sash in single-hung and double-hung styles, so the sash will not slam shut. Weatherstripping creates a tight seal against outdoor elements. Matching fiberglass mesh screen to protect against insects. 10-year limited warranty on aluminum windows.
