Sash windows and casement windows are two popular window styles with distinct differences:
Sash Windows
Sash windows open by sliding vertically or occasionally horizontally. They are often associated with traditional and period properties, providing a classic aesthetic.
Sash windows have two panels that slide open, offering a wide opening capacity for ventilation. They were popular during the Georgian and Victorian eras and are still sought after for their beauty and heritage style.
Casement Windows
Casement windows open and close on a side hinge, similar to an entrance door. They can be designed to open inwards or outwards and often feature safety restrictors to limit their opening capacity.
Casement windows are commonly seen in modern properties and are the most common window style for new builds.
The choice between sash and casement windows depends on various factors such as the property type, personal preference, and specific requirements. Sash windows are known for their traditional aesthetics and wide opening capacity, while casement windows are popular for modern properties and their ability to create a tight seal when closed.
Both types of windows can be made using insulated frames and sealed effectively. The decision between the two depends on factors such as budget, aesthetics, efficiency, and the type of property.
Sash windows are often associated with traditional and period properties, while casement windows are commonly found in modern homes.
In summary, the choice between sash and casement windows depends on the specific needs and preferences of the property owner, as both styles offer unique benefits and aesthetics. For more information, you can refer to the following sources: Sash Window Repair & Restoration
Which Type of Window is More Energy-Efficient, Sash or Casement?
Casement windows are generally considered to be more energy efficient than sash windows. This is because casement windows close and lock tightly against the frame, offering a better seal, regardless of whether you are heating or cooling the air within the home.
On the other hand, sash windows have a higher tendency to let air in or out, leading to increased heating or cooling bills over time. While both types of windows can be made using insulated frames and sealed effectively, casement windows are often preferred for their tight seal and energy efficiency.
Modern sash and casement windows both come with standard double-glazed glass to boost the window’s insulation value. The slight advantage of a casement window in terms of energy efficiency is due to its locking mechanism, which provides a slightly tighter seal.
In summary, casement windows are widely considered to be more energy efficient than sash windows due to their ability to provide a tight seal when closed, helping to retain heat and improve overall energy efficiency.
