Energy Efficient Glass – Whats all that about?

Energy efficiency glass, also known as low-emissivity (low-E) glass, is a type of glass that is designed to reduce heat transfer through windows and improve energy efficiency in buildings. It has a thin coating on the surface that reflects heat back to its source, whether it’s the sun in hot weather or the heating system in cold weather. This helps to keep the interior of a building cooler in the summer and warmer in the winter, reducing the need for air conditioning or heating and saving energy.

Energy efficiency glass can help to reduce energy consumption, lower utility bills, and create a more comfortable indoor environment. It also helps to minimize the amount of harmful ultraviolet (UV) radiation that enters a building, protecting furniture, flooring, and other interior items from fading.

There are different types of energy efficiency glass available in the market, each with varying levels of performance. Some types of low-E glass have a higher solar heat gain coefficient (SHGC), which allows more solar heat to enter the building, while others have a lower SHGC, which reduces the amount of solar heat that enters. The choice of energy efficiency glass depends on factors such as climate, building orientation, and specific energy efficiency goals.

Overall, energy efficiency glass is an important component in sustainable building design and can contribute to reducing energy consumption and greenhouse gas emissions.
