Abstract. This works aimed to analyze and compare the thermal conductivity of traditional adobe and adobe using different fiberglass reinforced polymer (FRP) residue contents. A chamber made of MPD (Medium Density Particleboard) of sugarcane bagasse was used. The box is insulated to the outside and lined internally by insulation layers, one styrofoam, and a thermal blanket. A source of heat, incandescent lamp, in the lower part emits a constant heat that by measurements of thermocouples can be analyzed the incoming heat and that which passes through the sample. FRP is a widely used material which, in addition to generating a large volume of waste, also has a high degradation time. The FRP residue was pre-processed. Five treatments were analyzed: 0; 2.5; 5.0; 7.5 and 10.0% of FRP of dry soil mass. The equation K=P.E/ΔT was used to calculate the energy coefficient. The samples were submitted to tests for 3.33 hours each, corresponding to 1000 measurements, being measured at the frequency of 12 seconds. A solar radiation meter was used to measure the radiation of the lamp. Each treatment was submitted to 5 replicates, and the intermediate value was chosen. The thermal conductivities were: 0.86; 0.79; 0.74; 0.72 and 0.65W.m°Cˉ¹ respectively for the treatments 0, 2.5, 5.0, 7.5 and 10.0%. It was concluded that the greater the addition of synthetic fiber residues in the adobe will decrease the thermal conductivity, thus improving its thermal comfort.
