Homeowners are often faced with the decision of choosing between sash and casement windows when updating their homes. Both window styles have their unique features, advantages, and disadvantages. In this blog post, we will delve deep into the world of sash and casement windows, comparing them in terms of aesthetics, functionality, energy efficiency, and more. By the end of this article, you will have a better understanding of which window style is best suited for your home.
Sash windows, also known as double-hung windows, are a classic and elegant option that has been popular for centuries. They consist of two sashes, one above the other, that slide vertically to open and close. Sash windows are commonly found in period homes, particularly Georgian, Victorian, and Edwardian styles, and are known for their timeless charm.
Sash windows can be customized with various glazing options, including single, double, and triple glazing. They can also be adorned with decorative features such as horns, astragal bars, and sash lifts, which can enhance the overall appearance of the window.
Casement windows are hinged at the side and open outwards, either to the left or right. They are a more modern and versatile window style, suitable for various architectural styles, including contemporary homes. Casement windows can be designed as single or double casements, and can also be combined with fixed windows for larger openings.
Casement windows offer a clean and minimalistic look, with slim frames and large glass panes that allow for maximum light transmission. They can be customized with different glazing options, as well as various hardware styles and finishes to match the overall design of your home.
Sash windows operate by sliding the sashes vertically, which can sometimes require more effort than opening a casement window. However, modern sash windows come with counterbalance mechanisms, such as spiral balances or cords and weights, that make opening and closing the window easier and smoother.
One advantage of sash windows is that they allow for adjustable ventilation, as you can control the opening size by sliding the sashes to your desired position. Additionally, since sash windows do not open outward, they are a great option for homes with limited exterior space or those located near walkways or patios.
Casement windows are generally easier to operate, as they open and close with a simple turn of a handle. They can be designed with friction hinges or stays that allow the window to be held open at various angles, providing adjustable ventilation.
Casement windows are ideal for hard-to-reach areas, such as over a kitchen sink or behind a sofa, as they can be easily operated with a single hand. However, keep in mind that casement windows require sufficient exterior space to open fully, which might be a limitation for some homes.
Historically, sash windows have been associated with drafts and poor insulation due to their design. However, modern sash windows have come a long way in terms of energy efficiency. They now come with features such as double or triple glazing, draught-proofing, and high-quality seals, which help minimize heat loss and improve insulation.
Casement windows are known for their excellent energy efficiency, as they create a tight seal when closed. The window sash presses against the frame, preventing drafts and air leakage. Like sash windows, casement windows can also be fitted with double or triple glazing, as well as low-E coatings and gas-filled cavities, to further enhance their insulation properties.
Sash windows can be fitted with various security features, such as sash locks, sash stops, and reinforced glass. However, due to their sliding mechanism, they can be more vulnerable to break-ins compared to casement windows, especially if they are not properly maintained or secured.
Casement windows are generally considered more secure than sash windows, as they come with multi-point locking systems that secure the window at various points along the frame. Additionally, the window's outward-opening design makes it difficult for intruders to force the window open from the outside.
Sash windows can be more expensive than casement windows, especially if you opt for traditional materials such as timber. However, uPVC sash windows are a more affordable alternative that still offers the classic charm of authentic sash windows. Maintenance for sash windows can be higher, as they require regular cleaning, painting, and repairs to ensure smooth operation and prevent drafts.
Casement windows are generally more affordable than sash windows and require less maintenance. They are available in a variety of materials, including uPVC, aluminum, and timber, which can cater to different budgets and preferences. Casement windows are easier to clean, as they can be fully opened to allow access to both the interior and exterior glass surfaces.
In conclusion, both sash and casement windows have their unique features and advantages. The choice between the two will ultimately depend on your personal preferences, budget, and the architectural style of your home. Take the time to consider the various factors discussed in this article before making your decision, and you will be well on your way to finding the perfect windows for your home.
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.
