Ventilated Facades for Houses: Benefits and Applications
Ventilated facades for houses are building envelope systems that incorporate an air cavity between the external cladding and the building envelope. This configuration improves the protection of the home against weather conditions and enhances the thermal and hygrothermal performance of the building envelope as a whole, making it an increasingly common solution in contemporary residential architecture.
Benefits of a Ventilated Facade for a Home
In a detached house, a ventilated facade can simultaneously help improve energy efficiency, indoor comfort, protection against moisture and the durability of the building envelope. It also makes it possible to incorporate high-performance cladding and develop facade designs with a high degree of creative freedom.
Energy Efficiency and Indoor Comfort
The combination of continuous thermal insulation and a ventilated cavity helps to limit thermal bridging and reduces direct heat transfer through the facade. The constant circulation of air also helps to remove moisture and reduce condensation problems, contributing to a more stable external envelope and greater thermal comfort within the home.
How It Works in Winter and Summer
In summer, much of the solar radiation is reflected by the outer layer, while the heat accumulated within the cavity promotes the stack effect, reducing heat transfer to the interior. In winter, the inner envelope helps retain heat, while the ventilated cavity contributes to the thermal stability of the facade system and helps control condensation.
Fire Safety and Durability
The choice of cladding is fundamental in a residential ventilated facade. Extruded ceramic panels offer high dimensional stability, low water absorption and ease of cleaning, qualities that enhance durability and reduce maintenance requirements. Ceramics also offer suitable fire performance, although the overall fire safety of the facade must be assessed by considering all components and the complete system configuration.
Contemporary Design for Detached Houses
Ventilated facades can incorporate different formats, orientations, colours and textures. This allows for everything from minimalist compositions to stone-, concrete-, marble- or wood-effect finishes, integrating the external cladding into the home’s overall architectural language and creating a contemporary aesthetic without compromising technical performance.
exa|TECH| for Residential Ventilated Facades
Exagres’ exa|TECH| combines a ventilated facade substructure with lightweight, high-performance extruded porcelain panels. The panels’ cellular structure incorporates an additional cavity within the piece itself, complementing the ventilated cavity between the external cladding and the building envelope. This distinctive construction feature is combined with low water absorption, a variety of formats and finishes, and the system’s modular flexibility, allowing it to be adapted to both new-build and refurbishment projects, with technical support available throughout the design and installation stages.
