Microventilated double wall (013)
Facades formed by double walls present the problem of possible condensation of the water on the cold side of the insulation. This problem is hardly solvable when it is committed to preserve the water vapor diffusivity of the whole enclosure. The outer wall will hardly dissipate water vapor before it condenses. Harquitectes solve this problem in this house in Sant Cugat by means of punctual microventilations, allowing them to escape from the traditional image of cavity wall. Rainwater tightness is entrusted to the characteristics of the outer ceramic layer.
