The quantity of paper and cardboard waste in Indonesia ranks fourth among all waste types, constituting around 11% of the total waste volume. The practise of reutilizing substantial quantities of garbage holds significant importance in mitigating the potential harmful consequences associated with its disposal in landfills, such as increased deforestation, heightened greenhouse gas emissions, and various other concerns. This article investigates the feasibility of utilising recycled cardboard to insulate roofs as well as the potential effectiveness of the material in lowering interior and attic ambient air temperatures. To accomplish the desired goal, identical components were utilised to construct two test cells: a multiplex ceiling, unpainted multiplex walls, and an unpainted corrugated zinc roof. One of the models, referred to as the reference model, did not incorporate any roof insulation, while the other model utilised cardboard insulation. In the context of zinc roofs, which have the capacity to function as heat radiators, it is imperative to develop roof insulation that effectively hinders both conduction heat and radiation. Consequently, the utilisation of aluminium foil involves its attachment to the upper surface of cardboard insulation, serving as a radiative barrier. The evaluation of the efficacy of utilising cardboard insulation to mitigate indoor and attic air temperature is conducted through the comparison of three sets of models: single-layer, double-layer, and double-layer cardboard, in combination with roof ventilation systems. The research conducted revealed that the implementation of recycled cardboard insulation resulted in a significant decrease in temperature. The most notable reduction in temperature was observed when employing a double layer of cardboard insulation. This shows that using recycled cardboard can lower the temperature in both the attic and the living area, especially in buildings with zinc roofs. Using cardboard waste has a number of effects on society, the economy, and the environment. Certain changes have happened, such as more people knowing how to reuse cardboard, less cardboard being thrown away, more money for people who collect used cardboard, and easier access to building materials for people with lower to middle incomes.
