Flush Casement Windows

Our Standard Casement Windows are designed to combine modern aesthetics with long-lasting performance, making them the ideal choice for contemporary and traditional homes alike. Crafted using premium aluminium profiles, these windows offer excellent durability, smooth operation, and enhanced thermal efficiency for comfortable living throughout the year.

Built with precision and attention to detail, the system provides clean lines and a sleek appearance that complements any architectural style. The strong frame construction ensures stability and security, while high-quality sealing helps reduce external noise, dust, and unwanted air leakage.

Whether used for residential projects, villas, apartments, or commercial spaces, our standard casement windows deliver reliable functionality with minimal maintenance requirements. Available in multiple finishes, glass options, and configurations, they can be customised to suit both design preferences and performance needs.

Designed to maximise ventilation and natural light, these windows create brighter, healthier, and more energy-efficient spaces without compromising on style or strength.

Attention to Detail

Every Standard Casement Window is manufactured with carefully engineered aluminium sections that ensure precision fitting and a refined finish. The slim yet durable profiles create a modern appearance while maintaining structural integrity for long-term performance. Smooth opening mechanisms and premium hardware components provide effortless daily operation and dependable functionality.

Superior Weather Resistance

Designed to perform in varying climate conditions, the system offers excellent resistance against wind, rain, and dust infiltration. Advanced sealing technology helps maintain indoor comfort while improving energy efficiency by reducing heat transfer and air leakage. This makes the windows suitable for both residential and commercial applications.

Elegant Modern Finish

The clean and minimal design of the standard casement system enhances the overall appearance of any property. Available in a wide range of powder-coated and textured finishes, the windows can seamlessly complement modern interiors as well as classic architectural styles. The premium surface finish also ensures long-lasting colour retention and low maintenance.

Enhanced Security

Security and durability remain at the core of the system design. Reinforced aluminium framing combined with high-quality locking mechanisms provides added safety and peace of mind. The robust construction helps the windows withstand everyday wear while maintaining their smooth performance for years.

Energy Efficient Performance

The window system is developed to support improved insulation and indoor comfort. When combined with high-performance glazing options, it helps minimise outside heat and noise, creating a quieter and more energy-efficient environment. This contributes to a comfortable living experience while supporting modern energy-saving requirements.

Handles, Pegs and Stays

Following the successful launch of the new Rio Flush Fit window, including a traditional timber style appearance. REHAU are pleased to compliment the window by offering key locking, beautifully designed monkey tail and tear drop handles, pegs and stays.

 

REHAU are pleased to announce that we have introduced a 28mm Square Edged Bead as part of the Rio flush fit window range. The new Square Edge Bead allows for a more contemporary style flush fit window to be manufactured for greater versatility and styling. Available as a special-order option, the new Square Edge Bead can be used internally to complement a modern interior design with a grey foil, but keep a traditional timber look externally with a Turner Oak foil.

The Square Edge Bead will also fit with the Heritage vertical sliding window system. It provides a uPVC square bead option and works with the original aluminium bead where catches are fitted and if required for security standards. The Square Edge Bead design incorporates the low level detail that is already an integral part of the Rehau bead range. Currently available from stock, just ask your local sales contact for more information.
