Ventilated facades: new challenges for the construction sector

The construction sector has before it a set of challenges to overcome: the gradual loss of the craft of stonemason, the emergence of new regulations which establish more demanding quality standards for the construction, the commitment to the environmentthe demand in security from the premise that all accidents are avoidable, the rapid variation of the aesthetic criteria and constant innovation both in materials and construction systems. All of this makes a true industrialization of construction in the image and likeness to the developments that have followed other sectors.

One of the greatest advances towards industrialization had been in the facades: ventilated facade. It is a system of isolation from the outside where you create the "effect chimney", which is due to the warming of the outer wall and leads to a variation of the density of the layer of air of the intermediate space with respect to the ambient air, with the consequent movement of Ascension. The insulating effect achieved in winter you to limit the dangers of condensation and low temperature sensations. The internal temperature ranges not sharply despite interruptions of heating at night or the tips of the winter outside temperature fluctuations.

The ventilated facade system is based on a self-supporting structure against slabs with an insulation incorporated into the manufacture and whose most important quality is the ability to save time at work and significantly reduce costs. This is accomplished through a placement in dry, fast, that is not affected by the atmospheric effects, that does not require installation of fixed crane or perimeter networks, and which limits the waste generated and its treatment.

Ventilated Chamber is one step in the constructive evolution of the comfort and the environment, since it involves a few direct benefits on the air conditioning and thermal "health" of the building: uniform insulation of the building, without thermal bridges. As a result, there is a decrease in structural movements due to the variation of outdoor temperature and the dilatations differentiated between the different materials that make up a building. Energy costs are reduced, and the acoustic insulation improve.

The system is designed on a metallic structure that adds to the set a series of additional benefits, such as compensation for small problems from verticality and allow the dilatations and contractions of different materials.

Industrialized ventilated façade system allows adaptation to any type of external coating allowing complete freedom in terms of combinations and finishes, giving to the architect of great freedom to give the building its personal touch without changing the structure and cladding of the building.

The industrialisation of the sector is the solution to meet the new challenges in the construction.
