Windows With Integrated Blinds
Integral blinds are the perfect solution for Flush windows. Easy to use and seamlessly integrated, they’re available as manual, solar, battery- powered and mains powered. Ideal for privacy-screening and controlling light, unblinds are contained within the window itself and can be concealed discreetly when not in use and stay out of the way when the doors are opened, without hassle of cleaning, tangling or clanking in the wind
Expertise throughout every stage
Our expert technical team will collaborate with you, your builders, and your architect to ensure that our slimline sliding door is showcased to its full potential. We carefully level the track and drainage profile to achieve a flush floor finish from the inside to the outside. Additionally. we ensure that the outer frame remains entirely concealed both from the inside and outside, with an extended plaster finish. Typically, the
external face of the frame is exposed and presents a pleasing
appearance; however, if needed, it can be concealed using external finishing materials. Upon completion, the only visible profiles on the door are the 25mm vertical interlocking profile and the side sash locking profile. This means you get up to 94% of full glazing area which give you with an ultra-modern panoramic view.

Tilt Function: To ventilate the room while maintaining security, simply turn the handle to the horizontal position. This action allows the top of the window to tilt inward, creating a small gap for airflow without fully opening the window.
Turn Function: For enhanced ventilation or ease of cleaning, turn the handle to the vertical position. This action allows the window to swing inward like a door, providing full access to the interior of the room and enabling thorough cleaning.
However, it is important to consult the manufacturer’s instructions as sometimes the operating mechanism may vary.
