The program ThermalWall calculates some fundamental dynamic thermal characteristics, for a arbitrary wall composed of multiple homogeneous layers plans whose boundaries are submitted to sinusoidal variations of temperature or heat flow rate. This characteristics variables are: steady state thermal transmittance, time shift of the periodic thermal transmittance, time shift between the maximum temperature outside and inside, decrement factor. The physical quantities treated and their numerical procedures are those defined in the European Standard EN ISO 13786 December 2007 'Thermal performance of building components - Dynamic thermal characteristics - Calculation methods (ISO 13786:2007)'. This program must be reactivated once a month, but is completely free for unlimited personal and business use, and also the reactivation takes place for free and quickly with a button that automatically appears.
