The Role of Viroc in the construction of Ventilated Façades

Viroc is a composite panel consisting of a mixture of wood and cement particles called Cement Bonded Particle Board (CBPB). These panels combine the flexibility of wood and the endurance of cement, allowing a vast range of applications. One of the main applications of the panels is their use in façades. Find out about their advantages in this article.

Ventilated façades and wall linings were developed to protect buildings from the combined action of rain and wind, reducing the effects of water striking against the walls, keeping the inside of the building dry, as well as providing an aesthetically pleasing finish and undisputable benefits as regards thermal and acoustic insulation.

Ventilated walls:

  • Eliminate the risk of cracks;
  • Eliminate the risk of the wall lining material detaching itself from the wall;
  • Protect against the wall bending as a direct result of the climatic conditions;
  • Eliminate surface condensation (the presence of a ventilated allows the free circulation of air, facilitating ventilation and allowing interior water and any damp to be removed);
  • Endow lasting efficiency to the exterior insulant, which stays perfectly dry thanks to the excellent ventilation;
  • Are easy to install on-site regardless of the weather conditions;
  • Create a technical ventilated for the installation of pipes and ducts.

Viroc panels are an excellent option to use in ventilated façades, providing the durability of traditional building techniques, with increased thermal comfort of the buildings, thus leading to energy savings. Ventilated façades reduce the amount of heat that buildings absorb in hot climates thanks to the shading produced for the wall of the buildings, combined with the ventilation of the air ventilated between the panel and the wall, leading to savings in cooling costs as there is less need for air-conditioning.

In contrast, in winter ventilated façades retain heat thanks to an insulating layer against the wall of the building, leading to savings in heating costs. This system allows efficient natural ventilation, ensuring a high level of comfort for the home.

From the functional point of view, the façade comprises a support frame, comprising metal or wooden sections clamped to the wall of the building using brackets and clamping devices. The panel is installed as an “independent” layer that is added around the entirety of the building, forming a ventilated air ventilated between the back surface of the panel and the insulation layer attached to the wall.

As well as the attractive appearance of the Viroc panels, they can be used in new buildings or to refurbish old buildings, bringing numerous benefits, as listed here. With the installation of a ventilated façade, a range of faults can be corrected.

  • Cracks and warping;
  • Deterioration of the materials of the buildings;
  • Crumbling;
  • Displacements;
  • Faults in materials, such as concrete;
  • Excessive distortion;
  • Dampness stains;
  • Mould and/or other microorganisms;
  • Efflorescence;
  • Poor functioning of framework/corners;
  • Excessive vibration;
  • Ventilation problems;
  • Changes in the colouring of the material.

To ensure good application, this newsletter does not dispense with need to carefully read the technical dossier for the application of Viroc panels.

It is very important to ensure that the technical information, transmitted to your customers and applicators or installers, is always the best and the most precise. Therefore, because we want you to have the necessary technical information for the best use / installation of Viroc products, we leave you with a link for the manual installation of Viroc products, a vital tool for your business activity and also for the success of the quality of its installation.
