If your air is cooled sufficiently, a portion of the gaseous h2o vapor from the air will condense, creating liquid h2o. The highest temperature that may bring about condensation is called the “dewpoint temperature.” “Humidity ratio” is another specialized time period accustomed to characterize the moisture content of air. The humidity ratio of a parcel of air equals the mass or bodyweight of h2o vapor within the parcel divided with the mass or weight of dry (dampness-no cost) air from the parcel.

These contain an incompatibility Together with the delicate bricks and mortars encountered in older structures and an absence of insulation Qualities when compared with much more common plasters, resulting in a heightened chance of condensation. Replastering is usually one among the most costly elements of a growing damp cure.
