Vindtætte

Vindtætte is a Danish term describing something that is resistant to wind penetration. It is commonly used in two main domains: construction and clothing. In construction, vindtæt refers to components of the building envelope that prevent wind from entering the interior while still allowing for controlled ventilation where needed. A wind-tight barrier reduces drafts, helps maintain energy efficiency, and works in conjunction with moisture management systems such as vapour barriers and breathable membranes. It is distinct from airtightness, which focuses on preventing air leakage more generally; vindtæt elements are often specified with a wind-load or wind-pressure capability for doors, windows, and cladding.

In clothing, vindtæt describes fabrics or garments designed to block wind chill. Windproof materials may rely on tightly woven textiles, laminated membranes, or other barriers. Many vindtætte garments aim to combine protection from the wind with breathability, allowing moisture vapor to escape to reduce discomfort during physical activity.

The term appears in product specifications, building codes, and safety guidelines. While vindtætness contributes to thermal comfort and energy use, it must be balanced with ventilation requirements to prevent moisture buildup and indoor air quality problems. Testing methods vary by industry but may involve exposing a sample to simulated wind pressures and measuring air leakage or wind resistance. In everyday use, vindtætte implies a practical level of wind protection appropriate for the intended application, rather than a formal standard.
