SYSTEM 3E walls are designed to be airtight and resistant to wind infiltration. When the elements are stacked, they form a monolithic structure. The gaps between the elements naturally close under the pressure of the stacked layers, creating a tight seal. Additionally, the unique labyrinthine connection of the elements further prevents air from passing through.

For added protection, a layer of plaster with mesh is applied on both sides of the wall as a finishing touch. This not only strengthens the surface but also contributes to the wall’s overall resistance to wind and air penetration, ensuring excellent thermal and acoustic performance.
