Muros en tubos de cartón rellenos con aserrín como aislante térmico para climas fríos

Abstract

The thermic discomfort generated in cold climate is considered as a problem which engages the involving materiality of a living place. The surface material temperature is a variable that contributes to produce comfort inside itself. In this research was the searching of materials that possess thermic properties in order to be implemented in the facade walls system. The cardboard tubes have a thermic conductivity coefficient between 0, 14 to 0, 53 W/ (M*K), and the sawdust 0,071 W/ (M*K), therefore, it was built a facade walls system with these materials in a prototype using a 1:2 scale. Their surface temperature was analyzed to verify their efficiency, as well as it was taken the temperature of the traditional masonry system to stablish a comparison between them. After making the experimental tests the results obtained shown as average an enhancement of 3,3 °C in temperature between these two systems, it refers to, meanwhile the masonry system shown an increasing average of 0,9 °C from outside to inside, the cardboard tubes system increased 4,2°C on average, where this last temperature keeping a rank between 21°C to 24 °C, it has been being an appropriated temperature (according to the Givoni’s diagram) to generate a favorable habitability condition in contrast with the offered currently by the traditional construction.
