We believe that your home should be a reflection of your personal style. That’s why we offer a wide selection of French casement windows in a variety of colours and finishes. Whether you’re looking for a traditional or a more modern style, we have the perfect option for you. Our windows are also available in a variety of sizes to suit any opening.
A flying mullion attached to the master sash keeps the amount of plastic profile on show to a minimum, this allows even smaller openings to be used as fully Building Regulations Part B. compliant fire escapes. Our French casement windows can also be fitted with optional “Easy Clean” hinges for fast and hassle-free window cleaning and maintenance.
Enhanced Ventilation and Wide Openings
uPVC French casement windows are designed with two sashes that open outward from the centre, creating a wide, unobstructed opening. This allows for excellent airflow and natural ventilation, making them ideal for rooms that need fresh air circulation.
Energy Efficiency and Insulation
These windows are highly energy-efficient thanks to the uPVC material, which offers superior insulation. They help maintain a stable indoor temperature by minimising heat loss in the winter and keeping heat out in the summer.
Low Maintenance and Lasting Durability
uPVC is resistant to rot, rust, and corrosion, making French casement windows extremely low-maintenance. Unlike wooden frames, they don’t require regular painting or sealing.
