Venetian blind inside double glass in Illa Diagonal 
The exterior layer of the ventilated facade is a thick travertine sheet, perforated by a strict grid of windows, framed with a stainless steel profile.
<p><span lang="EN-US">The ventilated facade gets its sealing with the ventilated and drained air space. A perimeter frame is placed to hide this space in holes. It is called “premarco-telar”.</span></p>
<p><span lang="EN-US">The joinery is formed by a double leave window. The inner part can be opened to access the space where a venetian blind (with stackable and adjustable louvers) is placed, or open the whole system. This element is used on the south facade, the most affected by solar radiation.</span></p>
