This study was carried out, using toxicity test apparatus, to analyze toxic gases of heat insulation material and adhesives of composite panels used for the architectural surface material when a fire occurs. The findings of this study show that CO, CO2, HCOH, CH2CHCN and NOx were detected from styrofoam, reinforced styrofoam, polyurethane foam and glass fiber, but in the case of the polyu- rethane foam, HCl and HCN were detected as well. All the architectural adhesives released CO, CO2 and NOx, but HCHO was only detected from the adhesives for styrofoam, wood, tile, windows and doors; CH2CHCN was only from those for wood and stone; C6H5OH was only from those for wood. The toxicity index was also measured for architectural surface material and adhesives. Polyurethane foam showed the highest index, 11.7, and glass fiber was followed as 6.8. Reinforced styrofoam showed 5.7 and styrofoam revealed the least 4.9. In the case of archi- tectural adhesives, the highest ranking was those for stone 7.4, windows and doors 6.1, wood 5.3, tile 3.8, and styrofoam 3.7 were followed, respectively.
