Batlle i Roig Arquitectectura

Beyond the indisputable formal possibilities of a double skin glass facade: blurring the structural and / or functional order, giving uniformity,  vanishing the volume limits melting them with the sky, and so on; a double skin glass facade contributes little to improve thermal aspects in our climate. 

Batlle and Roig resort in this occasion to a curtain wall where partial structures are assembled at each slab front without physical continuity between them. Glass panes are then supported over those partial structures to close the façade (have a look to "Cadireta" curtain wall structure). Each two glass panes are framed with an aluminum frame made with unitized panels profiles. Is it then a unitized façade or a curtain wall one? Maybe a mixture?
