What makes a French window different from casement and fixed windows?

A French window is made up of two side-hinged windows that open outwards without a central mullion dividing the frame. This allows you to enjoy uninterrupted panoramic views and plenty of ventilation. They house a locking mechanism in the centre to secure the panes together. Casement windows also open outwards, but their style is different. They are often made from a single pane, and double casement windows have a bar separating the frame. Fixed windows don’t open at all. They are designed purely to bring in light and offer unobstructed views.

What glazing options are available?

You can choose double or triple glazing for your French windows. Triple glazing offers exceptional thermal efficiency and increased insulation.

Are French windows energy efficient?

Our French windows are incredibly energy efficient, offering U-values as low as 1.0W/(m²K) if you opt for triple glazing.

What is the difference between Heritage and Architectural French windows?

Our Heritage windows are optimised for slimmer sightlines to offer simplicity and a wealth of natural light. Our Architectural French windows, on the other hand, can achieve U-values of 1.0W/(m²K), which is slightly lower than the Heritage range.

How secure are aluminium French windows?

Our aluminium French windows are incredibly secure, protecting your home with multipoint locking that is PAS 24 approved.

What distinguishes French windows from standard casement windows?

French windows, unlike casement windows, don’t have a central mullion dividing the frame. When they are swung open, they create a wide opening that provides seamless views and unrestricted ventilation. These stylish windows add classic European charm with a modern flare.

Are there customisation options available for Architectural French windows?

Of course! We offer a range of 9 standard powder-coated colours, and 3 anodised colours for a high end finish, that can be used to enhance your window. We also offer dual colour options so that you can make a window that matches the interior and exterior of your home perfectly. If none of these are the right fit for you, we can create a bespoke finish with any RAL shade. You can also customise the hardware, handles, and glazing of your new window to offer you the perfect home upgrade.

Are Endurance’s aluminium French windows energy efficient?

Our Architectural French windows are incredibly energy efficient, keeping your house naturally warmer with increased insulation. With U-values as low as 1.4W/(m²K) with double glazing, and 1.0W/(m²K) with triple glazing, our aluminium French windows will save you money on your energy bills.

What security features are integrated into Architectural French windows?

The durable aluminium we use to craft our windows combined with our robust double glazing creates a solid barrier against intrusion attempts. Our frames are constructed with multipoint locking mechanisms that are PAS 24 approved, letting you rest easy knowing that your home is secure.

Can these French windows be paired with other products for a cohesive design?

Our product range is designed to elevate your home, which is why we create windows and doors as style partners. Browse our range of aluminium doors to find the perfect addition to elevate the aesthetics and performance of your entire home.

How do Endurance Aluminium French windows open?

Endurance Aluminium French windows open outwards, making them ideal for large openings and providing excellent ventilation. The design makes access easy and creates a grand, elegant entrance.

Are aluminium French windows energy efficient?

Absolutely. Each window is built around InsuLock multi-chamber thermal cores. This delivers thermal performance that either meets or exceeds UK building regulations. It helps keep your home warm whilst lowering your energy bills.

How secure are aluminium French windows?

They are designed with multipoint locking systems, PAS 24-approved mechanisms, and reinforced frames. This provides strong security while keeping a good appearance.

Can I customise aluminium French window frames to match my home?

Yes. You can choose from slim sightline Heritage frames, select RAL colours, and even opt for powder-coated or anodised finishes. This ensures your French windows match both modern and traditional homes seamlessly.

How much maintenance do aluminium French windows need?

Aluminium French windows require very little maintenance. Aluminium resists corrosion, rot, and warping. A simple wipe-down with mild soapy water keeps the frames clean. Occasionally lubricating the hinges and locks ensures smooth operation for years to come.

What is a French Window, and How is it Different from Casement and Fixed Windows?

A French window consists of two outward-opening sashes without a central mullion, creating a wide, unobstructed opening. They often include a handle and locking mechanism in the center.

Casement windows open outward like French windows but typically have a single sash hinged on one side, making them suitable for smaller openings.

Fixed windows do not open at all; they are designed purely for letting in light and providing unobstructed views.

What French Casement Window Glazing Options are Available?

French aluminium casement windows can be double or triple glazed. Choose triple glazing for an enhanced thermal efficiency and improved soundproofing.

What is the Difference between your Heritage and Architectural French Windows?

Our French Heritage windows offer slimmer sightlines for simplicity and plenty of natural light, whereas our French Architectural windows can achieve a U-value of 1.0W/m2K with triple glazing, which slightly beats the Heritage range. Contact us to discuss which range is better for your project, our expert team will be happy to guide you.
