Ventilated facades for healthy environments

A Eliane Tec – service Eliane Ceramic Tiles specializes in complete construction systems – has a portfolio focused on solutions that combine technologies and innovations in favor of sustainability and eco-efficiency in buildings. Among the possibilities of the brand, as Ventilated facades stand out for their energy efficiency, elimination of pathological manifestations and deterioration of the building, in addition to providing thermal comfort in indoor environments and facilitating the maintenance of outdoor areas.

As explained in the image beside, as Ventilated facades present a gap between the construction itself and the external cladding, attached to a special metal device attached to the facade. Through this cavity called the air chamber, ventilation occurs by the chimney effect, where cold air enters the bottom and heated air is removed from the top, allowing continuous ventilation in the vertical direction.

This air circulation provides, among several benefits, greater thermal comfort to indoor environments. This is because it allows low heat dispersion in cold periods and low absorption of hot air in months with higher temperatures., keeping the climate of interior spaces always mild. This reduces a building's energy consumption - used in air conditioning systems, for example - approximately 30%.

Beyond eco-efficiency, as Ventilated facades they also eliminate so-called thermal bridges - specific points in the structure of a building responsible for the heat exchange of external and internal environments in an uncontrolled way, which constantly changes the temperature of the interior spaces. This situation causes some setbacks, as structural and aesthetic imperfections. These variations accelerate the condensation process of air humidity, which can accelerate the appearance and proliferation of molds, molds and fungi. In addition to degrading the materials used in construction - causing damage and cracks in walls, you facades, ceilings and floors - which can trigger allergic reactions in people who attend such ventures.

"The system of Ventilated facades also promotes important reductions in building maintenance costs, since the high impact resistance, wind loads, chemical attacks and action of ultraviolet rays prevents the degradation of coatings applied on the outside, in addition to avoiding structural damage caused by rain due to low water absorption ”, explains the manager Eliane Tec, Karina Campos.

When it comes to cleaning and maintaining the façades, the union of the system with nanotechnology Cleantec reduces the periodicity of performing such tasks. In the case of application on facades, nanotechnology – a layer invisible to the naked eye – presents a combination of decomposition of organic matter and hydrophilicity – that is, rainwater itself helps to remove dirt from the lining surface. This makes it difficult for dirt to stick, which reduces the use of aggressive chemicals and promotes water savings, facilitating cleaning and reducing the frequency of maintenance of facades. The technology is a partnership between Eliane Tec and the Japanese company Toto.

Comprising a hybrid technology based on noble metals and titanium dioxide, O Cleantec is effective in preventing bacteria * and viruses **, eliminating these organisms. The product is applied on ceramic tile and has separate formula for each of their applicability, related benefits and their place of use. The Cleantec can be used in facades, walls, floors and countertops of commercial and residential buildings. Besides that, It has elements that guarantee the effectiveness and durability of the product
