The 1630 Vinyl Single-Slider window has dualpane insulated glass and heavy-duty weather stripping for protection against wind, rain, dust, and noise. The manufacturer says a warm-edge spacer system maximizes energy efficiency and improves the seal performance of the insulated glass units while allowing an unobstructed view with expansive glass. The window is available in two- and three-lite configurations, comes in a white, clay, or almond finish, and costs approximately $270.
