uPVC French Casement Windows
Fire Egress

The French casement window can open wide and when opened fully, the French casement window is large enough to double up as a fire escape. Ideal for keeping you and your family safe in case of an emergency.

Wide Opening

French casement windows provide a wide opening. Both sashes open to about 90 degrees and when both windows are opened simultaneously, one casement carries the central mullion providing rapid ventilation and unrestricted space and views.

Controlled Ventilation

The window opens independently from the slave sash, providing effective ventilation. Both vents can be opened fully as well as independently which allows you to control the level of ventilation within your room.

Low Maintenance

uPVC French casement windows are very low maintenance and will never require re-painting. A simple clean with a damp cloth will be all that’s needed to keep these windows looking as pristine as when you bought them.

Centre Mullion

The centre mullion is isolated from the outer frame – similar to a French door. When the French casement window is opened fully, the sash carries the central bar which provides a wide and unrestricted view.

High Security Locks

French casement windows come with a choice of high security locks so whether your window is on the ground or upper floor, your property will remain safe and secure. There is also a choice of locking upgrades for the particularly security conscious.

Why Choose French Casement Windows?

Open up your property with classic French casement windows. The beautiful uPVC French casement window will provide you with enhanced views, effective ventilation, and a traditional aesthetic. The French casement window gives you the same benefits as the classic casement window but gives a little more versatility.

Expert engineering is paired with a classic design to provide a beautiful window which doesn’t compromise on performance. The French casement window has no ‘centre vertical post’ with both side vents able to open fully. This means it opens just like a French door, giving you a wide and unobstructed view.

The French casement window also doubles up as an emergency fire exit – perfect for smaller openings. This is made possible through fire egress hinges that enable the French casement to open out to sit against the outside wall. This means that they are a fantastic safety feature and ideal as a bathroom window replacement without losing out on the inherent style that makes them a popular option.

French Casement Windows Designs

These French-style uPVC windows can be personalised in various designs to suit your property. If you wish to maintain a traditional appearance, either woodgrain finishes or Georgian bars will help you achieve the classic look you are after. There is a wide range of options for you to choose from when it comes to customising your French casement windows.

Or if you are looking for a more contemporary design, keep things sleek and stylish in white with chrome handles. The great thing about modern French casement windows is their flexibility when it comes to getting them installed. Your chosen installer will be on hand to help you get something that is going to suit your home and your tastes.

French Casement Windows Frame & Beading Options

French casement windows are available in two types of distinctive frame and beading: chamfered and ovolo sculptured beading.

Chamfered beading is chosen to achieve a more contemporary, straight-edged style whilst sculptured beading allows you to achieve a more traditional and decorative finish. With these options in place, you’ll be able to enjoy the freedom that comes with greater choice. This will make it easier for you to get a French casement window that is going to suit what you’re after.

Both of these options are available across a range of uPVC windows, giving you complete flexibility over design. Whether your home is modern, traditional, period, heritage, new build, or anywhere in between, you’ll be able to find a uPVC French casement window to suit exactly what you’re after.

French Casement Windows Thermal Efficiency

Feeling comfortable in your property is important when it comes to feeling at home, especially when those cold winter winds roll in. This is why the modern French casement window comprises a design that achieves an impressive degree of thermal efficiency. This means that you’ll be able to keep the elements out of your home without having to worry about missing out on the style and charm that makes French casement windows recognisable.

This is made possible by combining a thermally broken profile with high-performance, integrated weatherseals. Both of these elements work in harmony with each other to trap in pockets of warm air, allowing the heat from your central heating to stay in your home for a longer period of time. This means that French casement windows will work to make your home a warmer and more comfortable place to be across the course of the year.

Bringing this standard of thermal efficiency to your home will do more than just increase your comfort, it could also help you to save money too! This means that French casement windows will continue to bring value to your property long after they have been installed. By keeping the warmth from your central heating in your home for longer, you could find that you use it less frequently throughout the year. In turn, this could result in a lower annual heating bill.

French Casement Windows High Security

Getting the right French casement window installed into your property is going to do more than just offer you aesthetic appeal, they can also offer you complete peace of mind too. This is because the modern French casement window design comprises a range of features that ensures they offer exceptional security from the ground up. At a glance, this includes premium grade materials, high-security, multipoint locking systems, and professional installation.

Due to the fact that modern French casement windows are manufactured using premium grade materials, they are able to achieve an impressive degree of structural integrity from the ground up. Whether you opt for an aluminium, uPVC, or timber French casement window you can rest assured that they’ll be able to offer you an impressive degree of base security. This means that the French casement windows that you choose will be able to withstand a modern attack.

This standard of structural integrity is then enhanced further through high-performance, multipoint locking systems that engage at different parts of the frame to ensure security is kept consistent across the whole build. The importance of getting a proper installation with these locks is important, because if they aren’t integrated into the frame then they can be used as a leverage point to gain access into your property.

Low Maintenance French Casement Windows

One of the main advantages that modern French casement windows have over their traditional counterparts is how little upkeep they require to keep looking their best. This means that you’ll be able to enjoy a new addition to your home that is going to last the test of time without creating a range of headaches for you to deal with. With this in mind, French casement windows are sure to be a worthwhile investment for your property.

As the French casement windows avoid any of the maintenance pitfalls of older designs, you won’t have to worry about any bowing, twisting, warping, cracking, or discolouring that is going to have a negative effect on how the window looks and performs. In fact, all you’ll have to do is give them a quick wipe down with a damp cloth to keep them looking as good as the day that they were installed. It’s never been easier to enjoy lasting quality when it comes to your windows.

Not only is a low maintenance French casement window design important when it comes to convenience, but it’s also important when it comes to ensuring you’re getting the best for your money. If your window starts to rot or twist out of shape, it isn’t going to perform as it should. Not only does this pose problems with opening and closing, but it also could offer a security problem as a rotting frame will have weak spots that can be used as a point of leverage to enter your home.
