WebThe U-value of a glass is defined as the amount of heat transmitted through the glass in every 1 m 2 of area and in every 1 K (1 °C) of temperature difference. Example: 200 W of heat transmitted through a 10 m 2 glass under 10 K (10 °C) of indoor/outdoor temperature difference, the glass U-value = 200 W / (10 m 2 x 10 K) = 2.0 W/(m 2 K).
