Abstract

The paper deals with the protection of wood in wooden building constructions, in accordance to the current trends in the use of organic materials in the construction sector and also in the woodworking industry. The attention is paid to the assessment of the effectiveness of selected retardant protective substances applied to spruce wood that was thermally loaded for prediction of flammability properties and assessing the suitability of their application. In the experiment, there was used the modified testing method with evaluation of the characteristics of thermal degradation. At the same time, there were evaluated selected material characteristics, in relation to the adhesion of retarding coatings applied.

The paper deals with the design of quantitative evaluation resulting from the decomposition products of surface-treated wood in the combustion process. This proposal evaluation in addition to monitoring the quality characteristics of the surfactant treated wood will add information on fire protection and selected environmental characteristics (emission of volatile organic compounds).
