Facade design essentials: Understanding weathertightness and airtightness

Weathertightness and airtightness are vital considerations in modern facade design, fundamentally shaping a building’s durability, energy efficiency, and overall occupant comfort. While both contribute to optimal performance, weathertightness shields the structure from all external weather elements, while airtightness only refers to air movement, preventing air leaks that result in energy loss.

Facade design essentials: Understanding weathertightness and airtightness explores what is meant by weathertightness and airtightness, explaining how these qualities contribute to the overall performance of a façade system. Furthermore, it reviews different types of facade systems, showcasing their individual advantages in achieving reliable performance.
