HArquitectes

In line with the previous post (183), referring to this “new” way of conceiving architecture, we want to share this magnificent example of reusing material with you.

Again, wall structures and materials of mineral origin are imposed.

Here we aim to exemplify the careful use of materials with which HArquitectes resolve their architecture, and therefore their façades. On this occasion, only two materials are used: thermal insulation and perforated brick (gero). In the inner wall, the structural support, the brick is arranged in such a way as to withstand the loads transmitted by the slab. In the outer wall, the same brick is rotated to show its perforated surface, which ventilates the cavity between the two walls.

Façades formed by double walls may suffer from condensation of water on the cold side of the insulation. This problem is difficult to solve when the aim is to preserve the water vapour diffusivity of the entire enclosure. The outer wall will hardly dissipate water vapour before it condenses. HArquitectes solved the problem in this house in Sant Cugat by means of regular microventilations, which escape from the traditional image of a cavity wall. Rainwater tightness is entrusted to the characteristics of the outer ceramic layer.
