What does permeance measure in drying practices?

Permeance measures the ability of materials to allow water vapor to pass through them. This concept is crucial in drying practices, as it helps determine how effectively moisture can move through and be released from a material. When drying a structure after water damage, understanding the permeance of various materials can inform the drying process, as materials with high permeance will allow moisture to escape more easily than those with low permeance.

In the context of drying, permeance is specifically focused on the water vapor transmission of materials of specific thickness, influencing decisions on dehumidification and air movement during the drying process. It helps professionals assess how well materials can breathe and dry out after exposure to moisture, impacting the overall efficiency and efficacy of restoration efforts.
