Reflective glass is a type of glass which is treated with a metallic coating. This metallic coating enables the glass to reflect heat. This type of a glass reflects back the radiation, rather than absorbing radiation. These glasses are primarily used in environmental friendly structures with the purpose of reducing heat loss and gain. When the windows of a building are made from this type of glass sheets, the heat produced inside the building tends to remain in it.This can largely reduce the heating costs. Also, the heat from the outside environment stays outside because the radiation is reflected back. This helps to keep the building cool during the summers.These glasses also provide optimum light transmission and reduces glare. http://amplify.com/u/a16b8i
