What is Low-E Glass?
Low-E (low-emissivity) glass has a coating that allows natural light through without emitting radiant heat, helping to maximise light and energy efficiency. The coating will help to reduce the transfer of the sun’s heat into the home during summer. In the cooler months, the coating helps to reduce the amount of internal warmth escaping through the glass. Additionally, Low-E glass can filter out some UV radiation from sunlight to help reduce fading of upholstery, carpets and benchtops.
Sunergy™, EnergyTech™, SmartGlass™, ComfortPlus™ and Planibel G are all brands of Low-E glass. Jason Windows only sources Low-E glass brands that comply with Australian Standards and building codes, and meet clients’ specifications.
