Resumen
Este estudio da a conocer un sistema de muro de hormigón armado con moldaje aislante incorporado, llamado "lnsulating Concrete Form" (ICF) evaluándolo económicamente y comparándolo con sistemas tradicionales de muros utilizados en el país (albañilería de ladrillo y hormigón armado). El ICF, ampliamente utilizado en Canadá y Estados Unidos hace más de una década, consiste en un moldaje de espuma aislante de poliestireno expandido (EPS) o extruido (XPS) o poliuretano o un compuesto de cemento y perlas de EPS. Este moldaje posee un espacio entre las placas de espuma que contiene las armaduras y donde se introduce el hormigón. Por lo tanto, el muro ICF es básicamente un muro de hormigón armado, cuya única diferencia es la técnica de moldeado. Este moldaje queda incorporado en el muro, formando parte de la estructura del elemento. Este sistema es utilizado para construir los muros estructurales y no soportantes de viviendas, subterráneos, edificios para uso comercial y público.
Los moldajes de espuma no solamente proporcionan una continua aislación térmica, sino también un apoyo para las terminaciones interiores y exteriores. Aunque todos los ICF son idénticos en principio, las variadas marcas difieren en los detalles de sus formas, centros de hormigón y otros componentes, como también en la metodología de uso del sistema.
El sistema ICF ofrece una aislación térmica muy superior a muros de albañilería de ladrillo y hormigón armado. La aislación acústica y resistencia al fuego son similares y en algunos casos superiores a las otorgadas por muros convencionales de albañilería u hormigón armado. Es cierto que el ICF es más caro (es recomendable utilizarlo donde el volumen de muros a construir sea elevado) que los otros sistemas de muros, pero con el tiempo, la inversión superior se puede recuperar sólo por concepto de ahorro de energía en comparación con muros de albañilería y hormigón armado tradicionales.
This work shows a Reinforced Concrete wall system with incorporated insulating forms, called " Insulating Concrete Form (ICF). Its economical evaluation as well as its technical comparison with traditional wall building systems used in the country are made (Brick works and Reinforced concrete). ICF is well known and it has been used in Canada and the U.S.A. for more than a decade. The ICF consist of an insulating foam form made of expanded or extruded polyesthirene (EPS or XPS respectively ) or Polyurethane or a cement and EPS pearls compound .These forms leave a space between two foam plates where the frames are located and the concrete is poured into. Therefore , the ICF wall is basically a reinforced concrete wall and the only difference being the forms technique. These forms become part of the wall itself and are integrated parts of the structure element. This system is used to build structural and partition walls in houses, basements and buildings The foam forms not only give a continuous thermal insulation, but also are the indoors and outdoors finishing material support. All the ICF manufactured by different companies have the same basic principle, and the products offered differ from each other in their shape details, concrete cores and other components, as well as in the system's applications methodology. The ICF system offers a much higher thermal insulating capability than the brickwork walls and reinforced concrete walls. Its acoustical insulation and fire resistance are similar and sometimes better than the ones of conventional walls made of brickworks or reinforced concrete. The building cost with ICF system is higher ( manufactured recommendations are that ICF be used where the wall building volume is high) than with other methods, but considering time, the higher investment can be recovered in terms of saving thermal energy compared to traditional masonry and reinforced concrete walls.
