Incredible value heat insulation: UW 0.67 W/m2K
System strength: 100 mm
Unique fitting evenly with the glass: Rebated by only 3 mm between glass and frame on the outside
Even fitting: Even to the frame externally and internally
Fibreglass window sash: More security, less distortion and lighter
Basic burglary protection: Standard mushroom-pin lock (optional RC2)
Fitting: Fully concealed with rotary limiter as standard

Josko combines four benefits in the Safir uPVC/aluminium window: Even, slim, warm and robust. The revolutionary uPVC/aluminium window also lets more light in thanks to its slimline frame.

Something
special

NEW! Flush windows with glazing bars

From now, available with 9 mm glass recess outside – this allows for an elegant combination with 25 mm slim glazing bars.

More light

The inclined glazing rebate lip lets more light into the room and creates a clean look. The incline also improves air circulation.

Unique fitting evenly with the glass externally

A Josko specialty: Rebated by only 3 mm between the glass and frame - with a modern design, the window can practically be cleaned with a simple wipe!

Even with frame

All our modern window systems are externally even with the frame and glass, which follows the trend towards architecture with clean lines.

Optimal sound and heat insulation and seals

Josko windows are sealed in three ways. They ensure excellent airtightness and protect against noise and heat loss.

Safir – even with the frame internally

With our Safir window series, the internal and external frame are even on the inside.
