fuktregulerende

Fuktregulerende describes a property of materials or systems that can absorb and release moisture in response to changes in ambient humidity, with the aim of stabilising relative humidity in a space or product. The mechanism is primarily hygroscopic sorption, where water vapour is taken up when humidity rises and released when it falls. This buffering can help reduce condensation, limit mold risk and minimize moisture-driven damage to sensitive materials.

In building and interiors, fuktregulerende materials include breathable wall components and natural fibre insulation such as lime plaster with hemp or wood fibre boards, clay plasters and other hygroscopic finishes. These materials allow moisture to move in and out rather than form a sealed barrier, contributing to a more stable indoor climate and potentially lower peak humidity. In textiles, fuktregulerende fabrics aim to move moisture away from the skin and balance the microclimate, using hydrophilic fibres or engineered structures to manage sweat and humidity.

Benefits of fuktregulerende materials include improved occupant comfort, reduced condensation and mold risk, protection of architectural materials, and potential energy savings by reducing the need for active ventilation or dehumidification. Limitations include dependence on climate, ventilation, and proper design; performance varies with thickness and construction details; aging and cost considerations can affect long-term effectiveness. Related concepts include hygroscopicity, breathability, and moisture buffering in design.
