Timber Casement Windows

What are timber casement windows?

Timber casement windows are hinged on one side, allowing the window sash to swing open (a sash being a moveable part of a window). Each sash is typically fitted with one single or double panels, each panel is separated by glazing bars.

The ingenious design of casement windows ensures optimal ventilation, allowing you to customise the airflow in your home. When it’s time to close up, the window sash snugs up against the frame, creating a secure seal that shuts out any unwanted drafts. So, embrace the smooth operation and undeniable charm of timber casement windows, as they effortlessly transform your home into a haven of style and comfort.

Frequently Asked Questions

This is entirely dependent on purpose and integration. For the best part Casement Windows are more energy efficient as they employ a rigid design which allows for better gasket sealing & reduction in thermal heat loss? In general, this window type tends to be cheaper than other window types such as sliding sash windows, box sash windows and top hung windows.

This window type employs a simple double/triple hinge system to hold the window unit in the frame. The window unit has an integrated locking/latch mechanism with an internal linkage arm to connect locking pins in the frame. The frame will be composed of hardwood and will feature a set of window runners that allow the window to move outwards / inwards. The gasket on the window frame allows the window unit to make a tight seal with the frame.

In general, Casement Windows does a better job of preventing heat loss thanks to a simpler hinge system here there are less moving parts and a better opportunity to form a tight gasket seal. Double-hung windows employ a tracking system that has multiple points where air may be able to get past the gaskets (especially as the gaskets begin to fatigue over time).

This will depend on your look, feel & price preferences. UPVC tends to be a cheaper alternative, but, without the premium look & feel offered by Hardwood. Hardwood Casement Units tend to be more durable, offer a much smoother feel & luxurious appearance and, as a window are generally more satisfying due to the build quality and material weights.

A regular window usually consists of a stationary pane of glass that is fixed to the frame of the window. In contrast, a casement window is hinged on one side and opens outward with the help of a crank handle.

Casement windows are often designed to be more energy-efficient than regular windows because they seal tightly when closed, minimising air leakage. They also offer better ventilation options as they can be opened fully to allow for more airflow.

People choose casement windows for several reasons. Firstly, they offer excellent ventilation because they can be fully opened to allow fresh air into the room. This can be particularly beneficial in areas with poor air quality or high humidity.

Secondly, casement windows are generally more energy-efficient than regular windows. When closed, the window sash presses tightly against the frame, creating a seal that prevents air from leaking in or out. This can help to keep the home more comfortable and reduce energy bills by minimising the need for additional heating.

Finally, they just look better. They have a classic, elegant look that can add to the overall design of the home. Casement windows are available in a wide range of materials, colours, and styles, so you can choose a design that complements your home’s architecture and decor.

The main difference between casement and flat casement windows is the way they open.

Casement windows are hinged on one side and swing outward with the help of a crank handle. This allows for maximum ventilation and easy cleaning, as the window can be opened fully to allow access to both sides of the glass.

Flat casement windows, on the other hand, are hinged at the top and open inward with the help of a handle. They are often used in modern buildings and offer a sleek, contemporary look. They can also be more energy-efficient than traditional casement windows because the sash presses tightly against the frame when closed, creating a strong seal that prevents air from leaking in or out.

Casement windows are generally considered to be more energy-efficient than other types of windows because of their design. When closed, the window sash presses tightly against the frame, creating a seal that prevents air from leaking in or out. This helps to keep the home warmer, reducing the need for additional heating, which can lead to lower energy bills.

Additionally, because casement windows open outward, they allow for better ventilation than other window types. This can help to reduce the need for air conditioning in hot weather, further reducing energy consumption.

The energy efficiency of a casement window can also depend on factors such as the quality of the window itself, the materials used in its construction, and the quality of the installation. Choosing high-quality, energy-efficient casement windows and having them installed by a professional can help to maximise their energy-saving potential.

Casement windows are generally safe for bedrooms as long as they are installed and maintained properly. They can offer good ventilation and easy egress in case of an emergency, as they can be fully opened to allow for escape or rescue.

For this reason, it’s important to choose high-quality windows with safety glass and secure locking mechanisms.

While casement windows have been used for centuries, they aren’t old fashioned. Far from it, in fact, we think they offer a classic, timeless look that is often associated with older homes and buildings, and we aren’t alone. They’re a popular choice among homeowners and builders for a variety of reasons. For example, casement windows offer excellent ventilation and energy efficiency, and their simple, elegant design can complement a wide range of architectural styles.

In recent years, there has been a trend toward more minimalist, contemporary design, which has led to the popularity of flat casement windows and other modern window styles. However, traditional casement windows continue to be a popular option for homeowners looking for something a little more classic.

While there is nothing you can do 100% deter a burglar from breaking and entering into your home, there are steps you can take to make your property and windows more secure, and therefore harder for a burglar to access. For example:

  1. Install window locks: Installing good-quality window locks can help prevent burglars from prying the windows open. There are several types of window locks available, including sash locks, keyed locks, and deadbolts.
  2. Use reinforced glass: Replacing the standard glass in your casement windows with reinforced glass can make it much more difficult for burglars to break in. Laminated or tempered glass can be a good option for added security.
  3. Use security screens: Installing security screens over your casement windows can add an extra layer of protection against burglars. These screens are made from strong, durable materials that are difficult to cut or pry open.
  4. Add window bars: Installing window bars can be an effective way to prevent burglars from gaining access to your home through your casement windows. However, this can also detract from the aesthetic appeal of your home and may not be appropriate for all design styles.
  5. Trim vegetation: Keeping shrubs and trees trimmed away from your casement windows can help to deter burglars by removing potential hiding spots and making it more difficult to access the windows.

Yes, casement windows are excellent for ventilation. When fully opened, casement windows provide a larger opening than many other types of windows, allowing for more air to flow into and out of a room. The design of casement windows also allows for air to flow from multiple directions, which can help to create a natural breeze and keep a room cool and comfortable.

Casement windows are designed to withstand normal wind loads and should not be damaged by typical wind conditions. However, extreme wind events such as severe thunderstorms can potentially damage casement windows.

To minimise the risk of wind damage, it’s important to choose high-quality windows that are designed and tested to meet local building codes and wind load requirements. Additionally, regular maintenance and inspections can help to identify and address any issues before they become more serious.

Casement windows operate with a smooth and efficient mechanism. By using hinges attached to one side of the window frame, they swing open like a door. A crank handle is used to operate them. When you turn the crank handle, the window sash swings outward or inward on the vertical hinge, allowing for excellent ventilation and easy cleaning. When closed, the window sash presses tight against the frame, creating a secure seal that prevents drafts and enhances energy efficiency.

Casement windows offer numerous advantages, which is why they’re such a popular choice for homeowners. They give you excellent ventilation, allowing a refreshing breeze to fill your home. With their unobstructed view, casement windows bring in ample natural light without breaking up the view. They’re energy-efficient, keeping your home comfortable while reducing energy costs. But most of all, they’re easy to operate and maintain, and their design means they have enhanced security as well.

Timber casement windows from Windows & Doors UK are designed to be highly energy-efficient. We prioritise both the beauty of natural timber and the energy-saving benefits it can offer.

Our timber casement windows feature high-quality timber frames that act as natural insulators, helping to minimise heat transfer and maintain a comfortable indoor environment. To further enhance energy efficiency, we offer double or triple glazing, which provides additional layers of insulation between toughened glass to reduce heat loss.

Additionally, our expert installation team ensures that our timber casement windows are properly sealed and weatherstripped, minimising air leakage and preventing drafts. This meticulous installation process further contributes to the energy efficiency of our windows.

Yes, casement windows are known for their secure and safe design. Equipped with appropriate locking mechanisms, casement windows offer excellent security features.

The hinged design of casement windows provides a high level of security. The window sash is firmly attached to the frame with multiple points of contact, making it difficult for intruders to force open the window from the outside.

Our timber casement windows for example, are equipped with robust locking systems to further enhanced security, preventing unauthorised access and deterring potential break-ins.

With proper care and maintenance, our timber casement windows can last for several decades. High-quality wood, such as the sustainably sourced durable hardwoods we use in our new windows, offers better longevity compared to lower-grade woods.

Furthermore, our expert woodworkers ensure proper finishing and sealing of the wood to help protect it from moisture, rot, and other environmental factors that can impact its lifespan.

To prolong the lifespan of your wood casement windows, regular maintenance is essential. This includes periodic inspections, cleaning, and refinishing or resealing as needed. It is important to address any signs of damage or wear promptly to prevent further deterioration.

Of course. Before you do, ensure the structural compatibility of your home and that you’re complying with any local regulations. If you’re unsure, consult a reputable supplier and manufacturer like Windows & Doors UK.
