What is a ventilated façade, and why will it define architecture in 2021?

Ventilated façades improve buildings’ energy efficiency and thermal insulation, extending the lifespan of projects thanks to the minimal maintenance they require.

Sustainability and reusing natural resources are two concepts key to new urban city planning, where inclusive architecture is gaining more and more popularity.



Given this new landscape, and the fact that more emphasis is going to be placed on renovating existing offices and homes (as proposed in the EU’s Green Transition Plan in a bid to combat climate change) research and development into new construction materials has led us to rethink the way we build and inhabit spaces.

Improving buildings’ energy efficiency (they produce 40% of energy consumption and 30% of CO2 emissions on the planet) and designing healthier spaces has become a priority for architects and professionals in the sector. Solutions such as L’AC natural wood, ventilated façades and bathrooms prefabricated by Butech, and sterile products such as the Krion® mineral compact and XTONE (PORCELANOSA Group) all represent steps forward in this direction.

What are ventilated façades?

Ventilated façades improve buildings’ longevity thanks to energy saving (they reduce lighting consumption by up to 30%) and the thermal insulation they provide to home interiors.

A ventilated façade consists of a supporting wall, air chamber, insulating layer over the support and, finally, a layer of cladding.

Butech is the company responsible for designing, consulting and evaluating each ventilated façade system, all with the PORCELANOSA Group guarantee and quality.

What are the advantages of ventilated façades?

Ventilated façades offer a number of advantages in comparison with traditional systems. Let’s look at some of the main benefits:

  • They promote energy savings and reduce electricity spending by up to 30%.

  • They improve thermal insulation because they completely envelop the building, eliminating thermal bridges. The air chamber makes the façade more efficient and improves insulation thanks to the ‘stack effect’ it creates.

  • They make buildings healthier, with higher resistance to extreme temperatures and humidity.

  • Less maintenance, more durability. In contrast to traditional façades, these systems don’t require ongoing repairs, increasing longevity and improving integration with the urban environment.

  • They reduce on-site construction times and optimise human resources (façade manufacture, distribution and installation are carried out by the same supplier).

The most frequently-used materials for ventilated façades

Amongst the most frequently-used materials for ventilated façade systems are ceramics – thanks to their excellent value for money, minimal maintenance and durability. Also sheets in Krion®: a sustainable solid surface mineral compact, backlit and join-free, with thermoforming properties and high resistance to extreme environments making it adaptable to any façade.

Why are ventilated façades the future?

Ventilated façades are one of the most efficient, safe and sustainable construction systems for building enclosures. The easy installation, improvements they lend to a building’s overall structure and sustainable composition make them a solution fit for the architecture of the future.


Ventilated façades and Exterior Insulation Finishing Systems (EIFS) are two different types of façade construction systems. But the important difference between them is that a ventilated façade provides better thermal insulation efficiency and durability. And because they require next to no maintenance and can be provided in customised designs, these systems can mask any imperfections buildings may have.

This type of façade adapts to the technical needs and qualities of each individual project: they’re installed directly over a building’s overall structure and are more durable than other systems. If you’d like to know more about these types of solutions, visit your trusted Porcelanosa store where you can get a bespoke quotation.

If you want to improve a home’s façade, you could install cladding inspired by natural materials or a ventilated ceramic façade.

There are a large number of façade systems in construction, all varying according to their weight (lightweight or heavy). Thanks to their innovative and sustainable composition, Butech’s lightweight façades have become the best option for building renovations. Other types of façades include prefabricated façades built with EIFS, or traditional façades made from brick, stone, wood or ceramics.
