As a professional window cleaning and after builders cleaning company, we are required to continually work with glass suppliers to ensure we are up to date with the latest glass technology. One type of glass which is becoming increasingly common when it comes to new home construction in Sydney is Low E Glass.

The glass was originally used in commercial office buildings due to it’s ability to increase energy efficiency (by reducing heat loss) and is starting to become a popular choice for residential homes (prevalent in new homes built in Sydney’s North Shore) due to it’s ability to reduce the amount of UV rays, heat and glare coming into the home when compared to standard glass.
