The single casement window is a classic type of window that is both beautiful and practical. It's an unobtrusive window, with a single sash that opens outward on hinges for splendid ventilation and clear sight lines. Its features have been greatly improved in recent years, expanding to include better quality materials and more energy-efficient designs. It has standard multi-point locks, weatherstripping, insulated glass and other features that make it both durable and safe for a family to live inside. Commonly casement windows are used in residential homes, offices and other commercial settings where the taste for natural light or a breeze can be satisfied. With a range of styles and finishes, the single casement window can be adapted to just about any architectural design.
