Vindtætteheden
Vindtæthed refers to the ability of a material or construction to resist the passage of air. This property is crucial in building envelopes and outdoor gear to prevent unwanted air infiltration or exfiltration. In buildings, good vindtaettedt contributes to energy efficiency by reducing heat loss in winter and heat gain in summer, thereby lowering heating and cooling costs. It also plays a role in maintaining indoor air quality by controlling ventilation and preventing the entry of pollutants.
Materials are tested for their vindtaettedt using standardized methods, often involving controlled air pressure differences across
Poor vindtaettedt in buildings can lead to drafts, discomfort, and increased energy consumption. Conversely, excessive vindtaettedt
