When choosing windows for your home, the options can seem overwhelming. Two popular styles that often come up in the decision-making process are casement windows and sash windows. Both have their own unique features and benefits, and understanding the differences between the two can help you make the best choice for your home. In this blog post, we will delve into the world of casement and sash windows, comparing their design, functionality, energy efficiency, and more.
Casement windows are hinged at the side and open outward, either to the left or right. They typically have a single pane of glass, providing an unobstructed view and allowing for maximum natural light. Casement windows can be found in a variety of styles, including traditional, contemporary, and even cottage-style homes. They can be customized with different materials, colors, and hardware to suit your home's aesthetic.
Sash windows, also known as double-hung windows, consist of two panels that slide vertically within a frame. These windows have a classic, timeless design that has been popular in homes for centuries. Sash windows are often seen in Georgian, Victorian, and Edwardian-style homes, but can also be adapted to suit modern designs. Like casement windows, sash windows can be customized with various materials, colors, and hardware to complement your home's style.
Casement windows are easy to open and close, thanks to a crank or lever mechanism. This makes them an ideal choice for hard-to-reach areas, such as above a kitchen sink or behind a sofa. The outward-opening design also allows for excellent ventilation, as the entire window can be opened to let fresh air in.
Sash windows operate by sliding the panels vertically, which can require more effort than the crank mechanism of a casement window. However, sash windows offer the advantage of being able to open both the top and bottom panels, providing better control over ventilation. Additionally, sash windows can be fitted with child safety locks, making them a popular choice for families with young children.
Casement windows are known for their excellent energy efficiency. When closed, the sash presses tightly against the frame, creating an airtight seal that prevents drafts and heat loss. This can result in lower heating and cooling costs for your home.
While sash windows can also be energy efficient, they may not provide the same level of insulation as casement windows. Due to their sliding design, sash windows can be more susceptible to drafts and heat loss. However, modern sash windows can be fitted with energy-efficient features, such as double glazing and weatherstripping, to improve their performance.
Casement windows are generally low-maintenance, as they can be easily cleaned from the inside of your home. The hinges and crank mechanism may require occasional lubrication to ensure smooth operation, but overall, casement windows are a durable and long-lasting option.
Sash windows can be more challenging to clean, especially on upper floors, as they need to be cleaned from the outside. The sliding mechanism may also require more frequent maintenance, such as lubrication and alignment adjustments. However, with proper care, sash windows can also provide many years of reliable use.
Casement windows are considered to be very secure, as the locking mechanism is embedded within the frame. This makes it difficult for potential intruders to force the window open. Additionally, the outward-opening design can act as a deterrent, as it is more challenging to climb through than a sliding window.
Sash windows can also provide a good level of security, especially when fitted with additional locks and safety features. However, due to their sliding design, they may be more susceptible to break-ins if not properly secured.
In summary, both casement and sash windows offer unique benefits and drawbacks, making the decision largely dependent on your personal preferences, home's design, and specific needs. By carefully considering the aesthetics, functionality, energy efficiency, maintenance, and security of each window style, you can make an informed choice that will enhance the beauty and comfort of your home for years to come.
Casement windows are the most common style of window. They feature hinged panels that swing open and closed. Casement windows are available in single panels or multiple panels. The direction a door swings, either to the right or the left, is called the handing. In addition to handing, window are identified as either inswing or outswing depending on whether they open into the house or towards the outside.

This newly built private house is in Sydney, Australia. The area occupied by the fenestration system in our scheduled design drawings was up to more than 110 square meters. A wide range of design details made the perfect mix of modern aesthetics and traditional sophistication, the simulated vertical hung windows with tilt & turn opening systems in this home are absolutely breathtaking. SDLS (Simulated Divided Lites with Spacer Bar) brings some historical vintage feeling to the whole building without losing any energy saving performance. Long narrow fixed windows creating larger-than-life expenses, coupled with German high-end systems made this project stand out from the rest.
The client's idea was to maintain a certain vintage feel, and our aim was to meet the energy efficiency needs and standards of modern houses as much as possible while maintaining a retro design. Doorwin’s 61S simulated hung windows with tilt & turn openings is a respectful modernization of a classic architectural masterwork.
Why choose the tilt and turn opening method?
Because it generally has better air seals than sliding, single hung, or double hung window frames. Tilt and turn windows form a complete seal when fully closed, this means they are less prone to water leakage, and cold draughts and you’ll keep more of your heating indoors where it belongs. They can be opened in the upper tilt way to ventilate at a minimum opening status and are easy to clean outside of the glass; when there’s a good day, they can be opened as normal inward casement windows.
Our well-crafted bespoke systems enhance the functionality and panoramic view of this modern house.
Huge, fixed glass walls up to seven meters long and two meters high bring great lighting and open views, making it really refreshing to the mind. Five meters high long narrow windows give the whole building a contemporary aesthetic.
