What Is a Ventilated Facade? Materials and Useful Data

Sustainability and the efficient use of natural resources have become fundamental requirements for every architectural project. In this new landscape, ongoing research and studies have led to the emergence of new materials and construction systems aimed at sustainable development. One increasingly common example is the ventilated facade, which ensures that a building's envelope is safe, efficient, sustainable, and durable by subtly and effectively integrating air renewal. Its ease of installation, contribution to the building's overall structure, and sustainable composition make it a highly attractive alternative for all types of construction.

Buildings account for 40% of global energy consumption and 30% of CO2 emissions; consequently, improving energy efficiency has become a priority for architects and industry professionals. Ventilated facades stand out for addressing this issue, offering multiple advantages over traditional enclosure systems. In addition to promoting energy savings, they reduce lighting consumption by up to 30%, improve thermal insulation, increase the building's health, offer greater resistance to high temperatures and humidity, and require less maintenance, ensuring greater durability.

But how does a ventilated facade actually work? The ventilated facade is a solution consisting of an air cavity that surrounds the building's exterior facade. The system is composed, from the inside out, of a support wall, an air cavity, an insulating layer applied to the support, and a cladding layer. In cold climates, the air acts as a barrier against heat loss. In warmer climates, meanwhile, this air cavity allows the interior to remain insulated, preventing excessive heat gain.

Although a ventilated facade requires minimal cleaning and maintenance, direct contact with the outdoor environment can lead to dirt deposits that affect its appearance. The advantage is that the dirt does not penetrate, remaining trapped on the outer layer of the panel. To prevent this buildup, periodic cleaning with water is recommended, using soap only if necessary. Furthermore, in the event of any breakage, the pieces can be easily replaced without the need for complex construction work.

As this is the layer exposed to the elements, choosing the right materials and components is crucial. Below, the experts at Porcelanosa suggest several options for effective ventilated facade cladding, featuring various styles and appearances.

Ceramic Facades

Ceramic is an ideal choice due to its price-to-quality ratio, minimal maintenance, and durability. If a ceramic cladding is chosen, it is recommended to opt for those with higher resistance, such as STON-KER®, an exclusive material that effectively adapts to outdoor environmental conditions.

KRION® Facades

KRION® is a homogeneous mineral compact (Solid Surface) without joints or pores, making it sustainable, backlit-capable, resistant, and durable, while incorporating advanced fastening systems. Furthermore, the thermoforming capacity of its pieces allows for a wide range of custom designs.

XLight Facades

XLight is a large-format, thin-gauge porcelain tile that is an unalterable, resistant, and lightweight material. Thanks to its physical and mechanical characteristics, it is ideal for use in ventilated facades. XLight differs from other facade systems due to its dual anchoring system: chemical (polyurethane adhesive) and mechanical (stainless steel clips, which allow for the rapid attachment of the porcelain panels to the facade's metal structure).

Stone Facades - FV Stone

Natural stone cladding offers all the advantages of a traditional ventilated facade, while adding a textured, natural appearance characteristic of materials such as granite, marble, and slate. The aesthetic diversity of these stones allows for the creation of rustic ventilated facades, with shades ranging from grays and blacks to ochres, browns, and pinks.

The ventilated facade presents itself as a suitable solution for extending the service life of any type of architectural project. To learn more about cladding suitable for this type of enclosure system, visit the Porcelanosa online catalog.
