What Is a Casement Window?
Casement windows are one of the most common window styles used in the UK. They are attached to the frame using hinges and open outward, allowing good ventilation and easy operation.
When closed, the window presses firmly against the frame, which helps create a strong seal against wind and rain. Because of this, casement windows are often chosen for modern homes as well as commercial buildings.


Stormproof Casement Windows
Stormproof casement windows are designed with an overlapping section that closes over the outer frame. This improves weather protection and helps keep the window sealed during strong winds or heavy rain.


Flush Fitting Casement Windows
Flush casement windows sit level within the outer frame rather than overlapping it. This style is often seen in older properties and is popular with homeowners who want a more traditional appearance that suits period homes.
What Is a Sash Window?
A sash window is a traditional window style made up of two sliding panels called sashes. These panels move vertically within the frame, allowing you to control airflow without the window opening outward.
Sash windows are commonly associated with Georgian and Victorian homes and remain one of the most recognisable features of period architecture.


Traditional Sliding Sash Windows
At Darcy Joinery, we manufacture traditional sliding sash windows that maintain the traditional appearance while including modern improvements such as:
- Double glazed units with a 16mm cavity
- Draught proof seals to reduce heat loss
- Secure locking handles
- Smooth operating mechanisms
This allows homeowners to enjoy the character of traditional timber windows with improved comfort and energy efficiency.
What Is the Difference Between Sash and Casement Windows?
The main difference between these two styles is how the window opens. Casement windows are hinged and open outward from the frame. Sash windows slide vertically within the frame using two moving panels.
Casement windows are commonly used in modern homes, while sash windows are often chosen for period properties where maintaining the original style of the building is important.
Both designs can be manufactured in timber and fitted with double glazing to improve insulation.
Duplex Glazing for Traditional Window Designs
Some properties require narrow glazing bars that are difficult to achieve using standard double glazing. This is particularly common in conservation areas where maintaining the traditional appearance of the window is important.
Our duplex glazing system creates the appearance of individual panes while using a single double glazed unit. Spacer bars are placed inside the glass and timber glazing beads are applied to the outside surface, creating a realistic multi pane effect while still improving weather protection and insulation.
