Glass With Super Thermal Insulation Properties. An Important Element In The Fight To Reduce Heat Consumption In Buildings

For many years the glass industry has provided highly efficient insulating glass systems with low U values as well as with various solar transmissions. This paper deals in particular with the solar contribution to the heating of buildings, state-of-the-art in the manufacturing of heat-insulating glasses with low-emissivity coatings and gas filling, and the influence of the window on the heat requirements of buildings.
