Moisture balance of the partition This is an assessment of the balance between the moisture that penetrates the building envelope and the moisture that is vented to the outside. This parameter affects the durability of the building and the comfort of its occupants. In practice, this balance helps to reduce the risk of water vapour condensation in walls, roofs and ceilings. Designers analyse it as early as the stage of selecting materials and the arrangement of the individual layers of the partition. In doing so, they take into account the vapour permeability of materials, ventilation and the conditions prevailing on both sides of the structure.
Excess moisture This can lead to the growth of mould, a reduction in thermal insulation performance and the gradual deterioration of building materials. For this reason, appropriately selected membranes, vapour barriers and ventilation gaps are used. A well-designed partition wicks away moisture in a controlled manner and retains its properties for many years. The right moisture balance also improves the energy efficiency of the entire building.
