This is what protects the outer brickwork from any runoff water, it projects out at the bottom. If you chose to not have a cill, an alternative form of drainage would be required.
This depends on the product as not all have couplers that are the correct depth.
Yes, we are not able to offer concealed

Neutral Self Cleaning Glass
Self-cleaning glass uses a microscopic coating with a unique dual-action.
The first stage is “photocatalytic” – the coating reacts with daylight to break down organic dirt.
The second stage is “hydrophilic” – instead of forming droplets, rainwater hits the glass and spreads evenly, running off in a “sheet” and taking the loosened dirt with it, also drying quickly without leaving streaks
Blue Solar Control Self Cleaning Glass
Solar control glass can be used to minimise solar heat gain and help control glare. In temperate regions, it can be used to balance solar control with high levels of natural light. Solar control glass is ideal for large folding doors where solar heat gain could be an issue.
This attractive blue glass, combines dual-action, self-cleaning properties with solar control performance for a cooler internal environment. Specially designed for the optimum unit ideal for folding doors. It uses daylight and rainwater to breakdown and wash away organic dirt from exterior surfaces. Its unique blue colour also helps keep internal temperatures cool whilst still maintaining excellent light transmittance.
Glass only requires to be toughened in critical locations as defined by part “N” of the building regulations.
Part N (Glazing) deals primarily with safe breakage of glazing in critical locations, manifestation of glazing to prevent collision, safe cleaning of windows in commercial buildings, prevention of falling from windows and glazed openings.
