Why Airtight?

Airtight building is not only required by law in many territories but is also essential for protecting against mould and heat loss. Building regulations and standards mandate airtight constructions for a good reason: the airtightness layer helps to save energy, prevent moisture damage to structures, and avoid unpleasantly warm indoor temperatures in summer.

Thermal insulation is crucial in decoupling the indoor climate from the outdoor climate. The temperature difference between the two climate zones creates air flow, also known as convection. During winter, warm air from inside the building exits through the structure into the exterior surroundings. The airtightness layer prevents this air flow, thereby hindering the loss of warm air to the outside. Additionally, it helps to prevent mould and moisture damage to building structures due to condensation, and provides a comfortable indoor climate in summer.
