UD-Value Calculator

Utilize our UD-Value Calculator on our SL Thermo+ doors to see how much you can reduce in heat transmissions on your door.

UD-Value Calculator

The heat transfer coefficient U of a door plays an essential role in modern building envelopes. Thanks to the ASSA ABLOY SL Thermo+ 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 UD-value calculation. The UD-Value Calculator will help you to do just that.
