What is the thermal coefficient Lambda?

The thermal coefficient Lambda is the measure of thermal conductivity and determines the heat flow through a material due to heat conduction. The lambda value shows how well or how poorly a material conducts heat and thus how suitable it is for thermal insulation. Materials that conduct heat poorly (e.g. insulation materials) have a low lambda value, materials with strong heat conduction (e.g. concrete) a high one. The thermal conductivity of most materials increases slightly at higher temperatures. In general, lambda is the heat output in watts that is conducted through 1m2 of a 1m thick layer of a material when the temperature difference between the two surfaces is 1K.

Welcome to the ENERsign® U-Value window configurator:

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.
