We are uncompromising in the product we offer:
ENERsign®primus elements with at least triple glazing with a U-value glass of 0.52 W/m²K and a g-value of 53%. Other designs and special glasses are available on request.
The U-value window is also called heat transfer coefficient and according to the standard DIN EN 10077 it indicates the amount of thermal energy lost through a window to the outside.
The U-value window is calculated using the formula W/(m²K), i.e. watts per square metre and Kelvin. This value refers to the entire window and defines the amount of energy per unit of time that flows through an area of one square meter when the air temperature on both sides differs by one Kelvin. The lower this value is, the less energy or heat the window emits.
