DYNAMIC CONDENSATION CALCULATIONS

Ensuring the protection of the environment

The building shell is normally crossed by a flow of water vapor. The transmission of water vapor is generally correlated with the microclimate of the building's interior and with the characteristics of the materials used in the structure of the building.

Renovations of existing and historical buildings, with insulation improvements on the inside means it is not always possible to get all the answers to a Glaser test, especially when this is not checked.

There are many factors that influence the formation of interstitial condensation: from material composition, the exposure of the wall, to the presence of moisture and the percentage of rainfall.

Therefore, in the design phase or whilst the diagnosis is being carried out, it is important to perform appropriate checks in order to eliminate the risk of condensation inside and outside of the building so as to avoid mould forming and structural damage occurring.

The dynamic condensation test allows you to understand how a wall will react when in the presence of interstitial condensation over time.Because of this, even if condensation is detected it will be able to understand if levels are likely to decrease or increase over time, leading us to choose precisely what is required in the design stage of an improvement operation.

As part of passive renovations, an Ener-Phit verification is mandatory in the case of internal insulation.
