Sliding Door FAQs
What is ‘self clean’ glass?
Self-cleaning glass combines advanced self-cleaning technology with solar control performance, making it a highly desirable option for homeowners seeking premium glazing solutions. A specialist coating is applied to the glass surface, designed to actively break down organic dirt while reducing the adhesion of inorganic particles.
When exposed to rainwater, droplets spread evenly across the glass to form a smooth sheet rather than beading. This process lifts and carries away loosened dirt as the water drains from the surface, significantly reducing maintenance requirements. The result is clearer glass, less frequent cleaning, and a visible improvement in appearance that delivers lasting performance you can see.
Why is clip in bead important and why is it better than wedge gasket?
Our patented clip bead is used on our bifolding doors to retain the glass units in the sashes. The traditional method of retaining glass in aluminium glazed products is to locate an aluminium bead profile and pre load it with the use of a wedge gasket. Essentially there is enough room to locate the bead profile in the sash and then a wedge gasket is fitted to take up the gap and means the bead cant be removed. This is time consuming and fiddly and the result isn’t always as consistent in terms of appearance as some might hope. The patented clip bead we developed has a pre fitted gasket and utilises a plastic clip element that enables the bead to be clipped in incredibly easily and quickly. The result is not only neat and the sightlines consistent but also saves your installer a large amount of fitting time.
What is the Maximum Width that the Sliding Doors will open to?
The Korniche Cortizo 4700 sliding door is designed to create truly expansive openings, with the ability to span widths of up to 6400mm. This impressive capability allows for large, uninterrupted glazed areas that maximise natural light and provide seamless connection between indoor and outdoor spaces. Engineered for strength and smooth operation, the system combines slim sightlines with robust aluminium profiles, delivering both striking aesthetics and reliable performance across wide spans.
What is PAS 24:2022 Security?
Certified to the advanced PAS 24:2022 standard, their strong durable aluminium frames come with enhanced security from our high strength shoot-bolts.
The lockable shootbolt handles have an innovative anti-back drive feature engineered into it. Even unlocked, a forced entry attempt can’t rotate the handle to open the door.
Are your Sliding Doors available on a Double or Triple track system?
Korniche sliding doors are available with either a double or triple track system, depending on the number of sashes specified and the opening configuration required. Customers can choose from 2, 3, 4, or 6 sash arrangements, allowing the system to be tailored to suit a wide range of opening sizes and design preferences. This flexibility makes it possible to achieve large glazed spans, smooth sliding operation, and the ideal balance between fixed and moving panels for each individual project.
