Key Design Features

Slim & Flush

The SUNFLEX UK SAF window is the epitome of modern design, featuring stylish square-edged aluminium profiles that sit neatly and flush with the outer frames when the window is closed.

The high performance SAF system is manufactured with slim, thermally broken aluminium profile to maximise the amount of glass and make the most of the views out. The SAF window is available with either double or triple glazing in a huge range of styles to perfectly match the requirements of your home.

Square edged frames

Designed to match the look of our award-winning sliding and bifold doors, the SAF window system features square-edged frames on both inside and outside of the window to create a striking, contemporary appearance.

Fixed frame windows
Side hung opening sashes
Top hung opening sashes
Tilt & turn windows

The versatile options and stylish design of the SAF window allows us to incorporate a combination of fixed and opening sashes to custom-make each window to the exact specification of your home.

Advanced thermal performance

Thanks to its advanced design the SAF window is able to combine its contemporary looks with Building Regulations Part L compliant thermal efficiency and advanced weather
performance standards.

Between the internal and external aluminium frames a large polyamide thermal break limits the heat loss – helping keep heat inside the room to keep your heating bills down and making the room feel warmer. With double glazing the SAF window is capable of achieving a U-value from just 1.4W/m²K whilst with triple glazing the window can achieve highly impressive performance with U-values from just 1.0/Wm²K†.

Complete peace of mind

Feeling secure in your own home is a core requirement for any window system and the SUNFLEX UK SAF windows are designed to offer complete peace of mind.

The windows hold the BSI Kitemark™ certificate and the latest in independent PAS 24:2022 security testing alongside the prestigious Secured by Design™ award, ensuring the system can be incorporated into the design of a wide range of projects, from replacement windows and period property renovations, to stylish inner-city extensions and ultra-modern new homes*.

Versatile design options

The versatility of the SAF window profile allows for the creation of a stunning range of window design options – making it an option for more than just casement designs. From large picture windows that maximise light and perfectly frame the view out, to incredible frameless glass-to-glass corners that add a real ‘wow’ factor to any room.

The square-edged frame of the system perfectly lends itself in accompanying our award-winning ultra-slim sliding doors and high performance SF75eco bifold doors – whether that’s as eye-catching gable glazing above the doors or as fixed frames alongside the doors – enabling you to combine products to create a continuous and consistent overall glazing solution.

Stylish handle designs

As the perfect finishing touch the SUNFLEX UK SAF windows are available with stylish handles, available in a choice of finishes.

The contemporary lockable handles are manufactured from solid 316 marine-grade stainless steel ensuring they don’t just look good, they are also built to last. The slender design ensures the handle sits in-line with the frame so as to not obstruct the view out, adding a touch of elegance to the finished look of the window.

The handles are available in black, anthracite grey, brushed stainless steel and brushed brass.

Opening Styles

Side Hung

Opening out from the side, the handle is usually half way up the window. They feature egress hinges to help escape in an emergency and easy clean hinges to slide the window along when open and clean the outer glass.

Top Hung

Opening out from the bottom with a handle along the bottom, this design can provide wider openings than side hung. Restrictor hinges limit how far the window can open with built in subtle finger latch to allow the window to open further.

Tilt & Turn

Ideal for providing a more modern window appearance, with larger openings than conventional open-out windows. The inward opening tilt-and-turn mechanism is ideal for high-level windows allowing them to be easily cleaned from the inside. Alternatively, the handle can be locked to give a tilt-only operation of the window for ventilation.

Fixed Frame

Whether utilised as individual picture window or integrated alongside opening sashes to create a casement window, our fixed frames provide a versatile addition to any window design. To create a seamless design you can even opt for a dummy sash to ensure a consistent design with the opening elements.
