Introduction

CYPETHERM HYGRO is a program designed to check for surface and interstitial condensation in building elements.

To do this, the application calculates the interior surface resistance factor by considering the critical surface humidity and analyses the vapour pressures and temperatures at the interfaces between the layers of the building elements, based on the hygrothermal behaviour of the materials and building products, and following the calculation methodology of ISO 13788:2012.

The calculation of the thermal transmittance is carried out in accordance with ISO 6946.
