Consequences of the use of ammonium sulfate as a fire retardant when producing the ecowool are considered. In the course of the study, the pyrolysis of selected insulation was conducted with the help of the device of synchronous thermal analysis with the simultaneous analysis of gas products by the mass-spectrometer. The availability of ammonia and sulfur oxide (IV) in gaseous products of the pyrolysis makes it possible to assume that the initial sample contains ions of ammonium and ions of sulfate and sulfite in its composition. The most probable source of these components in the initial material can be ammonium sulfate. The quantitative analysis for ammonium ion was conducted by spectrophotometric method. The amount of ammonia released in the atmosphere of premises greatly exceeds the permissible limits of SanPiN.
