UD-Value Calculator – Optimize Energy Performance

Make informed choices with Record’s U_D-Value Calculator. Designed to support the specification process, it lets you evaluate the thermal performance of our door systems based on your project’s unique conditions. Achieve energy efficiency, ensure compliance, and choose the right solution with confidence.

U_D-Value Calculator

The heat transfer coefficient U of a door plays an essential role in modern building envelopes. Thanks to the Record THERMCORD doors, unwanted heat transmission can be significantly reduced. Depending on the glass type and size, we can achieve values of U=1.1 W/ m2K. Since the parameters for glass and size play an essential role, each door must be recalculated for the U_D-value calculation. The U_D-Value Calculator will help you to do just that.
