K-Value

The k value has the unit W/m²K (watts per square meter and Kelvin). The unit shows that the k-value provides information about how much heat output per square meter disappears through the component with a temperature difference of 1 Kelvin between inside and outside.

The normal range of serum potassium levels for adults is 3.6-5.0 mmol/l. A serum potassium level above 5.0 mmol/l requires prompt monitoring.

The heat transfer coefficient (U-value) indicates the amount of heat that passes through 1 m² of a component per unit of time with a temperature difference of 1 K between the adjacent indoor and outdoor air. The smaller the U-value, the greater the thermal insulation. The unit of measurement is W/m²K.

THIS IS WHAT THE LAW REQUIRES. The Building Energy Act (GEG) stipulates maximum U-values for changes to existing buildings. For external walls this is 0.24 W/(m²*K).
