| Summary: | This work aims to obtain parameters of thermal performance of various types of plaster blocks for vertical sealing. The methodology consisted of making test elements with 8 types of plaster blocks, in addition to plasterboard of different densities. Thermal resistance, transmittance, capacity, and delay were calculated, according to the Brazilian standard NBR 15220. Thermal behavior tests were carried out with controlled heating through a heat source, digital thermometer, infrared thermography, and an instrumented thermal chamber developed for this work. The experimental results corroborated with the trend indicated by the calculated parameters. The massive and hollow blocks of 100 mm had the best results followed by the 76 mm hollow blocks. The 50- and 70-mm massive blocks were among those with the worst thermal behavior. The study through the thermal chamber and real test elements associated with the normative methods allowed the practical verification regarding the thermal behavior of the components.
