Abstract (English):	The following research work is part of the comparative evaluation of roofing materials marketed in the city of Cali and the area of influence and the elements that complement it, such as: Roof base and / or ceiling, establishing their thermal insulation capacity in the face of solar radiation, conduction and absorption phenomena occurring on the roof surface and at the level of the interior space. The research is structured based on the bimodal climatology (two dry periods and two rain periods interspersed) of the place. The test tubes (modules of 1 x 1 m) are located in the vicinity between Cali and Santander de Quilichao under real atmospheric conditions, taking into account the data issued by the Institute of Hydrology, Meteorology and Environmental Studies "IDEAM" and those thrown by the thermal measurement equipment located inside and outside the modules. Under this approach, different techno-constructive roof solutions are assembled in complete specimens whose walls do not include architectural management variables such as door and window openings. These envelopes, together with the floor envelope, are made in a sandwich panel system with a 10 cm polyurethane foam insulation that allows the variable walls to be isolated from the roof envelope given the phenomenon of thermal inertia. Next step, the temperature measurements are made inside and outside the test pieces since September 2017 and on the roof surface (Interior, exterior), determining the factors that trigger the increase in temperature within the space at a rate of the physical properties of the materials and of the heat transfer phenomena, the data is subsequently processed through a statistical analysis where maximum, minimum and average temperatures related to the hours are estimated for each module.

Abstract (Spanish):	El siguiente trabajo de investigación se enmarca en la evaluación comparativa de materiales de cubierta comercializados en la ciudad de Cali y área de influencia y los elementos que la complementan, tales como: Base de cubierta y/o cielo raso, estableciendo su capacidad de aislamiento térmico ante fenómenos de radiación solar, conducción y absorción ocurridos en la superficie de la cubierta y a nivel del espacio interior. La investigación se estructura partir de la climatología bimodal (dos periodos secos y dos de lluvia intercalados) del lugar. Las probetas (módulos de 1 x 1 mts) se sitúan en la inmediación entre Cali y Santander de Quilichao bajo condiciones atmosféricas reales, tomando en cuenta los datos emitidos por el Instituto de Hidrología, Meteorología y Estudios Ambientales “IDEAM” y los arrojados por los equipos de medición térmica ubicados al interior y exterior de los módulos. Bajo este enfoque se arman diferentes soluciones tecno-constructivas de cubierta en probetas completas cuyos muros no incluyen variables de manejo arquitectónico como aperturas de puertas y ventanas. Estas envolventes junto con la del piso, se realizan en un sistema panel sándwich con un aislamiento de 10 cm en espuma de poliuretano que permite aislar la variable de muros de la envolvente de cubierta dado el fenómeno de inercia térmica. Paso siguiente se realizan las mediciones de temperatura al interior y exterior de las probetas desde el mes de septiembre del 2017 y en la superficie de la cubierta (Interior, exterior), determinando los factores que desencadenan el aumento de la temperatura dentro del espacio a razón de las propiedades físicas de los materiales y de los fenómenos de transferencia de calor, los datos son posteriormente procesados a través de un análisis estadístico donde se estiman temperaturas máximas, mínimas y promedios relacionados con las horas para cada módulo.
