What is self-cleaning glass ?
Self-cleaning glass uses a surface treatment based on two fundamental principles :
Reaction to UV light
The photocatalytic coating naturally breaks down organic pollutants on the surface of the glass when exposed to light, particularly the sun’s UV rays.
Water-repellent effect
The surface of the glass is also treated to repel water, allowing rain to effectively clean the surface, carrying away decomposed dirt.
Advantages of self-cleaning glass
Low maintenance
The main added value of self-cleaning glass is its reduced maintenance. The surface treatment prevents dirt accumulation and promotes natural cleaning by rainwater.
Increased durability
Self-cleaning glass is designed to last. Resistant to weather and UV rays, it retains its transparency and properties for several years, thereby reducing replacement or cleaning costs.
Energy efficiency
In addition to their self-cleaning properties, certain types of self-cleaning glass, such as low-emissivity (Low-E) glass, contribute to the energy efficiency of buildings by reducing heat loss and optimising thermal management.
