The importance of natural ventilation: Louvres, Screenwalling and Loopholes

Natural ventilation is a basic bioclimatic concept that has always played an important role in architectural design for many reasons. For example, in the vernacular tradition of many countries, warehouses for both wheat and other food products were designed to allow air to circulate easily and keep products safe from moisture. On the other hand, ventilation in houses, as in all environments intended for collective use, was considered- and it is today- fundamental. In terms of health and hygiene, ventilation avoids the congestion of viruses and the spread of diseases. And for safety, it facilitates evacuation in case of gas or other fumes leak.

As a consequence of the nineteenth-century pandemics – cholera and plague, among others-, a reflection on the relationship between health and architecture began, allowing a leap of quality in the design of many European cities. Today, due to the COVID-19 pandemic, attention has been driven on this issue one more time, opening up again an old debate on the need to include natural ventilation in all architectural projects. At SAS, we are aware of the importance of natural ventilation. For these reasons, for years, we have included in our catalogue specific products to facilitate the circulation of air in closed and open spaces.

Slat Screenwalling

Finally, we present you with our most decorative element for ventilation, the Slat Screenwalling Lamas. In two previous blogs (part I and part II), we talked about the importance of screenwalling in ancient, modern and contemporary architecture. Due to its relevance, excellent finish and minimalist design, the products of this line are among our best sellers. This screenwalling, fabricated in two colours, allows the natural passage of the wind, generates privacy and guarantees an excellent finish. It is designed to complete fences and enclosures, and it plays with the slats tilt to limit the view from the outside.
