What is U-value in building physics?
The U-value (W/m²·K) measures the rate of heat transfer through a structure divided by the difference in temperature across that structure. Lower U-values indicate better insulation.
Calculate thermal transmittance (U-value) for multi-layer walls, roofs and floors, and verify required insulation thickness (EPS, XPS, mineral wool).
Engineered for mechanical, HVAC, piping, and design engineers in compliance with international standards (ISO, DIN, EN, ASME, ASHRAE). Load the interactive tool for real-time calculations and automated reports.
