The case of family-based farming Evaluación cuali-cuantitativa de aislaciones térmicas alternativas para viviendas. El caso de la agricultura familiar Viegas, Graciela Melisa Walsh, Carolina Barros, Maria Victoria Family-based farmers of Greater La Plata and Berazategui (Buenos Aires, Argentina) are conditioned by their position as leaseholders of land by which they live and work and by their fragile economicproductive situation. Low-cost dwellings with low habitability standards and poor insulating properties are observed. This paper proposes the exploration of alternative insulating materials through the reuse of resources. These materials may contribute to the improvement of both existent (recycling) and new dwellings. Such an exercise involved the measurement of the thermal transmittance of materials through hot box methods. Different analyses of the most representative materials were conducted during 2014; these elements were divided into four categories: natural fiber, plastic, paper and soil. Interviews and consultations were conducted in order to elaborate quantitative analyses that were contrasted with the opinion of potential users and the viewpoint of technicians involved in this social segment. Results show that corrugated cardboard and recycled polyethylene have good insulating properties, are affordable or obtained for free and reduce the amount of existing waste; likewise, users consider the use of these materials a possible solution if they solve sealing, humidity and condensation issues. Los agricultores familiares del Gran La Plata y Berazategui (Buenos Aires, Argentina) están condicionados por la situación de arrendamiento de la tierra en la que viven y trabajan y por su frágil situación económico-productiva. Se observa la construcción de viviendas de muy baja inversión con altos déficit de habitabilidad y deficiencias de la envolvente. Este trabajo propone la búsqueda de materiales alternativos para la aislación térmica de viviendas, reutilizando recursos. Estos materiales podrían colaborar tanto a la mejora de la vivienda existente (reciclado) como a la nueva. Para ello se desarrolló un equipo de medición de la transmitancia térmica de materiales, basado en el principio de “caja caliente”. Durante el año 2014 se realizaron mediciones de los materiales más representativos agrupados en cuatro categorías: fibras naturales, plásticos, papel y tierra. Las mediciones cuantitativas fueron contrastadas con la opinión de los posibles usuarios de estos materiales y la de técnicos que trabajan con este sector social, a través de entrevistas y consultas. Los resultados mostraron que el cartón corrugado y el polietileno reciclado tienen buena respuesta térmica, costo bajo o nulo, reducen un desecho existente y los usuarios consideran posible su aplicación si se resuelven problemas de estanqueidad, humedad y condensación.
