  • Easy data entry and immediate results
Features
Read full description

This application allows you to help in checking the existing and planning future isolation. After entering data on the temperature and humidity of the air and selecting all layers of the enclosing structure (starting from inside the building and ending with the exterior trim of the facade or roof) in the Thermal Transmittance Calc, you will receive information on all likely heat losses, as well as possible problems with humidity. A schedule will be built, according to which you can track how the temperature and humidity will change and where the dew point in the layers of the structure will be. - Easy to use, enter all the data and immediately get the results. - Ability to enter the temperature in both Celsius and Fahrenheit. - Ability to enter the size of the layer in centimeters and inches.
