Struggling to let more light into your home? Casement windows might be the answer. In this post, our technical design manager, Tommy Best, explains what a casement window is, and its benefits for Scottish homeowners. Read his insights that could help brighten your house.
Defining a Casement Window
Casement windows are hinged at the side and typically open outwards. They provide unobstructed views and excellent ventilation due to their single-sash configuration.
Characteristics and Functionality
Casement windows open with a lever or a push, offering homeowners control over ventilation and the amount of fresh air entering their homes. They come with several components, such as frames, sills, mullions and lock handles.
The lock handles are particularly important to ensure a tight seal when the window is closed. The locking mechanisms that CR Smith uses have a gearbox that drives locks on all four locking points in the frame and each shoot bolt is made from three layers of stainless steel for extra strength. This design minimises heat loss, making our double-glazed casement windows highly energy efficient—a key benefit for Scottish homes dealing with cold winters and blustery autumnal conditions.
uPVC, timber, and aluminium are all commonly used in the construction of these windows because they are durable and resistant to all weather elements. The panels close tightly into the frame, further enhancing thermal efficiency and reducing water ingress—an essential feature in Scotland’s often wet climate.
This style of window offers versatility while maintaining indoor temperature stability. Options range from side-hinged casements to fixed panels that don’t open but, with a good-quality slim frame, can still let light flood into your home.
Different types of Casement Window
Casement windows come in various designs, catering to different needs. Read on to discover the diverse types of casement windows and their unique features.
Side-Hinged Casement Windows
Side-hinged casement windows swing outward from the hinge on the side. This design allows for full opening and maximises ventilation. Homeowners often choose them for their ability to enhance air circulation in a room. They come in single or double-frame designs, known as French casement when they have two panels with a central mullion. These windows offer an excellent choice for those seeking improved natural light and fresh air entry into their homes.
The design makes cleaning the outside of the window easier. Egress hinges can also be specified on Lorimer casement windows which allow the window to open to 90° to provide fire escape.
With proper maintenance, side-hinged casement windows can add charm and functionality to Scottish homes while boosting security due to their robust framework and locking mechanisms.
Top-Hinged (Awning) Casement Windows
Top-hinged awning casement windows open from the bottom and hinge at the top. This design prevents rain from getting inside while letting fresh air flow in. They are perfect for Scottish homes because they offer great ventilation without risking water damage during a downpour. Homeowners find these windows ideal for hard-to-reach areas like over kitchen sinks or high on bathroom walls since they can pull in air even when it’s raining.
Awning casement windows also fit well with various materials, such as uPVC, wood, and aluminium frames, which adds to their appeal. Their unique opening mechanism enhances security because it is harder to force them to open from the outside.
These features make them a preferred choice for those who want to improve the indoor environment of their homes efficiently.
Fixed Casement Windows
Next, we have fixed casement windows. These types of windows do not open and are often found in bay window setups. They serve a special role by maximising the glass area to enhance views without opening functions. With the addition of our unique slimline frames, your home will have even more natural light flooding in.
Fixed casement windows are large, rectangular in shape, and designed specifically for those seeking unobstructed views of the outside. They are also known as a picture windows.
Lorimer casement windows are double glazed with an excellent insulation value, making them energy-efficient choices for Scottish homes. By combining them with operable casement frames, homeowners achieve both ventilation when needed and expansive views all year round. This blend offers a practical solution while adding aesthetic appeal to any home design.
Material Options for a Casement Window
When it comes to the material options for casement windows, homeowners can choose from uPVC, wood, or aluminium. Each material provides distinct advantages and factors to consider that can influence the appearance and functionality of the windows. At CR Smith, we have chosen to supply uPVC casement windows, which are manufactured at our state-of-the-art factory in Cowdenbeath, Fife.
uPVC
uPVC stands for unplasticised polyvinyl chloride. This particular type of plastic has become increasingly popular over the years and is the preferred material for casement windows in homes throughout Scotland.
Many homeowners opt for uPVC because it is competitively priced compared to timber or aluminium. The installation process of a uPVC casement window is also slicker and creates less mess. These windows are also cost-conscious and exhibit remarkable energy efficiency by retaining warmth.
We have also brought our own expert focus to the design and installation of uPVC windows to offer casement windows that fit snugly within the fabric of the building and give a smooth appearance to both modern and traditional properties. Given their durable plastic composition, they don’t require extensive maintenance. A simple wipe-down is sufficient to maintain their freshness and lighten your cleaning process.
Wood
Wood brings a classic look to casement windows. It’s the choice for homeowners who want their houses to have a traditional vibe. Wood frames offer an elegant aesthetic that blends well with older properties or those designed with a period appeal in mind.
Timber windows are more costly, potentially up to 50% more expensive than their uPVC counterparts. Wood also requires regular maintenance to stay in top condition, as homeowners need to treat it with preservatives to prevent rot and wear from weather exposure.
Despite these needs, many find the unique character and warmth of wooden window frames worth the extra effort and expense.
Aluminium
Aluminium stands out for its modern look and lasting quality. It costs less than wood, making it a smart choice for Scottish homeowners who want something different. This metal can also be shaped, allowing a range of window designs.
You can use aluminium in traditional casement windows or more contemporary styles like sliding or double-hung sash windows. Its strength means your windows stay secure and are easy to open when you need fresh air or an escape route.
Plus, recycling this material is straightforward, adding to its appeal for those who want to make eco-friendly choices at home.
Advantages of Casement Windows
Casement windows offer versatile ventilation, boosting indoor air circulation and freshness. Compared to some other window types, they also provide better security. Being particular about the shape and style of the frame will ensure your home looks good and benefits from optimal thermal efficiency.
On the flip side, always consider potential obstructions to the operation of a casement window but our expert team at CR Smith will always guide you through the best options available for your home.
Enhanced Ventilation
Casement windows open widely, letting in a lot of fresh air. This design makes them great for ventilation, which can help keep your home cooler on warm days. They are different from sliding windows or double-hung sash windows as they provide a larger opening for air to flow through.
This feature is especially good for Scottish homes during mild weather, when you want to enjoy a breeze without the need for a fan or air conditioning. On the cool side, the snug fit of these windows, when closed, enhances energy efficiency by preventing heat loss, making them thermally efficient choices for any home looking to reduce utility bills.
Better Security
Our Lorimer Casement windows also offer better security thanks to their high-grade stainless steel hinges and multi-point locking systems. Unlike traditional sashes that might be easier to force open, the hardware on casement models adds an extra layer of protection against break-ins.
Beautiful Details
The beauty of all quality windows is always in detail: the shape and size of the frame to let in the maximum amount of natural light, the standards of design and manufacture, the fit, and, ultimately, how it looks in your home.
For a really unique appearance, each Lorimer casement window can be designed with equal sight lines, to give a symmetrical appearance both inside and out, whether the window has an opening sash, a fixed pane or a combination of both. And with additional feature such as ornate astragals and stained glass, they can be truly personalised.
It is for this reason that CR Smith windows are bespoke. We have designed the slimmest frame available in Scotland, we manufacture every window to the homeowners’ requirements and each is hand-finished.
Casement windows stand out for their old style and versatility. They hinge on the side or top, offering unique designs in single or double panels.
Energy efficiency is a key benefit due to their tight seal feature. Choosing casement windows means selecting comfort, style, and efficiency for your home.
