Low E glass, short for Low Emissivity or Low Emittance, contains a microscopic coating that helps make the window more thermally efficient. The coating is thin, nontoxic, and virtually colourless.
The coating works by minimising the amount of ultraviolet and infrared light that can pass through the glass by reflecting it away and reducing radiant heat emissions.
The coating helps reflect heat back into the home in the winter and to the outside in the summer, helping homeowners save money on energy costs. In every season and any climate, Low E glass windows help to keep properties better insulated. Additionally, Low E windows protect the inside of the property from harmful UV rays while still allowing natural light to flow in.
Low E glazing can be either single or double glazing. When Low E glass is used in single glazing it must have a hard coat that is baked onto the glass. Hard coat Low E has a discolouration or haze in the glass.
Low E coating in double glazing is what is called a soft coat. This coating gives a very clear glass however can be easily scratched so it is applied on the inside between the two panes of glass. Soft coats perform slightly better than hard coats.
We recommend using a Low E coated glass like Viridians LightBridge product, or Australian Glass Groups Insulglass LowE range.
We believe this glass is the best value for money, delivering exceptional thermal insulation with a u-value of around 1.7 to 1.0 and excellent durability.
We have many glass options available, including laminate and acoustic glass. Please contact us if you would like more information.
