VENTILATED CONCRETEPolymer concrete for ventilated facades
Ventilated Facade System, a constructive solution for the cladding consisting of an enclosure organized in multiple layers: an inner sheet (existing enclosure of various materials), an air of varying width in which the thermal insulation is placed attached to the inner sheet and an outer sheet and natures of different materials (natural stone, cement, porcelain stoneware, extruded stoneware, phenolic panel, polymer concrete) connected mechanically to the inner sheet by a light metal substructure.
Of all materials used in the outer sheet of ventilated facades, we try here the polymer concrete composed of different types of aggregates bound by polyester resin material. There are multiple advantages that the polymer concrete offers on its use as a coating for ventilated facades, but perhaps one of the most important is its high water impermeability thus avoiding the need for placement of impermeabilizantespara sheets meet the standards of Technical Code Building, resulting in savings compared to other systems of ventilated facades in which if the installation of waterproofing sheets is necessary.
Employment in the coating of polymer concrete ventilated facades offers other advantages such as:
High strength (30.2 MPa support up front 7-9 MPa that traditional concrete supports).
Resistance to the action of most chemicals that prevents disintegration or deformation of polymer concrete.
Since its zero water absorption index, its impermeability and watertightness are ensured and smooth mirror surface permits an almost immediate evacuation of water.
Polymer concrete is an extremely lightweight material that allows custom manufacture of parts, thus contributing to greater ease of transportation and installation of precast polymer concrete.
Also, its fastness to cycles of freeze-thaw favoring the non-appearance of cracks and fissures in the ventilated facade, high impact resistance and minimal abrasion are other characteristics that make polymer concrete a material of high quality It requires virtually no maintenance.
Manufacturing precast polymer concrete using allows the realization of molds custom parts so that the possibilities for the design of ventilated facades expand.
The use on ventilated facades polymer plates precast concrete constitutes a constructive remedies for cladding ventilated to major advantages bring not only economic terms (since transport costs, handling and installation are cheaper) but also in terms of design aesthetic and its wide variety of finishes.
