Let’s get clear about self-cleaning glass

When it comes to self-cleaning glass it is important for clients to understand exactly its benefits.

A number of the rooflight products we offer at Natralight have self-cleaning glazing as part of their many unique features.

Along with being energy efficient, durable and providing ambient temperatures the main attraction of this type of glass is the lack of maintenance required. 

What does self-cleaning glass mean?

The British Standard of self-cleaning glass is BS EN 1096, which was introduced in 2016 to make the mystery of self-cleaning glass more transparent. This certifies that the glass has an official self-cleaning performance, using hydrophilic and photocatalytic properties that enhance the glass’ cleanliness.

True self-cleaning glass, as set out by standard BS EN 1096, works in a 2 stage process, with the first stage of the cleaning process known as ‘photocatalytic’ with the glass’ coating reacting with daylight to break down organic dirt.

The second stage is ‘hydrophilic’ where instead of forming droplets, rainwater hits the glass and spreads evenly, running off in a sheet, taking any loosened dirt with it plus it is quick-drying without leaving streaks.

Remember that true self-cleaning glazing is a premium product and although prices could be higher than standard rooflights; the benefits are plentiful.

What are the benefits of self-cleaning glazing?

  • A permanent self-cleaning coating will last the lifetime of your glazing
  • The glass stays cleaner for longer
  • Reduced glass cleaning bills
  • A clear view outside even when it's raining due to the sheeting effect
  • More environmentally friendly with less frequent use of water and detergents
  • Less dirt and grime will cling to the glass making cleaning quick and easy
  • Ideal for conservatory roofs and other hard-to-reach areas that can be difficult to clean

Maintenance tips for self-cleaning glazing 

  • Don't pressure wash the glass or you could risk removing or damaging the active coating 
  • Never use abrasive materials such as scouring pads, rubber squeegees, wire wool, metal scrapers or stripping blades
  • Avoid cream cleaners, window cleaner sprays and anti-mist agents as they may harm the specialist surface
  • Stay clear of chemical-based cleaning products as they can leave a film on the special coating and prevents it from working 
  • Any other repairs or maintenance needs to be carried out by a qualified self-cleaning glass installer
