Professional Builder has run a case study on a garden room build where the homeowner, named as Simon, opted for Korniche bifold doors fitted with self-cleaning glass, with low maintenance cited as the deciding factor. Korniche is an established UK aluminium bifold door and roof lantern brand, and the case-study format suggests this is a real-world install being used to illustrate why a customer picked a particular glazing spec, rather than a new product launch.
Self-cleaning glass generally works through a hydrophilic or photocatalytic coating on the outer pane: the coating breaks down organic dirt when exposed to UV light and helps rainwater sheet off in an even film rather than beading, which reduces streaking and the frequency of manual cleaning. That's how self-cleaning coatings work as a category — the source doesn't confirm which specific coating technology is used on this installation, so treat that detail as general background rather than a fact about this particular door.
Why this matters for UK trades
Bifold doors are now a standard spec on garden room and extension work, and glazing options — including self-cleaning coatings, solar control glass and enhanced security glazing — are increasingly a point of client conversation rather than an afterthought. For installers, being able to talk through what self-cleaning glass actually does (and doesn't do — it reduces maintenance, it doesn't eliminate cleaning entirely) is a useful bit of client-facing knowledge when quoting bifold installs.
