BIOCLEAN® – Roof Glass With Self-Cleaning Properties

BIOCLEAN® coated glass uses sunlight and rain to help keep your windows cleaner for longer, which can reduce how often you need to clean your windows compared to non-coated glass. By reducing the frequency of cleaning using water and cleaning products, BIOCLEAN® coated glass can help conserve water, contributing to lower water consumption.

In addition to its self-cleaning properties, BIOCLEAN® coated glass offers solar control benefits. It can help lower indoor temperatures on sunny days by reducing the amount of solar heat entering through the windows.

Our range of lower maintenance, self-cleaning glass is available in a choice of coloured tints.

HOW DOES BIOCLEAN® WORK?

BIOCLEAN® self-cleaning roof glass encompasses a special transparent coating embedded into the outer surface, which helps the glass stay cleaner for longer. It works by utilising daylight’s ultraviolet rays to break down any dirt into smaller particles. The rain or waterjet then naturally washes the dirt away.

Due to the nature of the coating, our self-cleaning glass performs when on a gradient, allowing the water to flow across the glass and avoiding any streaks formed by water droplets.

BIOCLEAN® acts 100% naturally by exploiting the dual action of daylight and rainwater.

how bioclean works

BIOCLEAN® is activated by the sun’s UV rays creating a photocatalytic process that breaks down dirt present on the surface of the glass.

bioclean how it works

BIOCLEAN® has hydrophilic properties, helping the water run off the glass surface easily, washing away the dirt, leaving your windows clean.

Tinted Roof Glass Options With Self-Cleaning Properties

BIOCLEAN® coating is available on clear and a range of tinted glass options.

Choose the BIOCLEAN®+ range which incorporates additional solar control properties into the coating to further minimise overheating, particularly important during the summer months.
