Kokonaislämmönläpäisy
Kokonaislämmönläpäisy, often referred to as the U-value or overall heat transfer coefficient, is a measure of how effectively a building component or structure prevents heat flow. It quantifies the rate of heat transfer through a unit area of the component for a unit temperature difference between the two sides. A lower U-value indicates better thermal insulation, meaning less heat is lost or gained.
The U-value is the reciprocal of the total thermal resistance (R-value). Thermal resistance considers the insulating
In building physics, kokonaislämmönläpäisy is a crucial parameter for assessing the energy efficiency of buildings. It
Factors influencing the U-value include the type and thickness of insulation used, the materials of the structural
