The Ponzio Ltd. makes available to all its customers this free software to determine the thermal transmittance Uw of windows.

This calculation is crucial to meet the parameters for energy efficiency as defined by D.M. minimum requirements and to get tax deductions of 65% described in the 2008 Budget.
However, it should verify that there are no values in their common transmittance limit different from those in force at the national level.

This calculation is performed according to the regulations currently in force, the UNI EN ISO 10077-1, and taking into account the transmittance Uf of each node constituting the frame, the value determined in accordance with the UNI EN ISO 10077-2.

In addition, this software allows you to know the value of Thermal Transmittance Uw of the frames taking into account the simplifications defined in the product standard EN 14351-1 for the CE marking of windows and doors.
