Flush Sash Windows & Their Popularity

A flush sash window features a sash that closes flat into the frame, creating a smooth, streamlined appearance. The absence of any overlap between the sash and outer frame gives it a neater look compared to standard casement styles. This design offers a clean, refined finish that works well on both modern homes and traditional properties.

Flush sash windows are especially popular on heritage-style projects, where homeowners want to retain period charm while upgrading performance. It’s a style that blends the best of both worlds, timeless design with modern efficiency.

Top Hung or Side Hung Configurations

Smart flush casement windows are available in both top-hung and side-hung opening configurations, offering flexibility for your project’s layout.

Top hung styles open from the bottom, swinging outwards from the top. This is useful for secure ventilation and upper-floor installations. Side hung windows open from the side, offering a traditional feel. Both options are designed to install smoothly and perform reliably for years to come.
