The article describes the impact of climatic factors on expanded polystyrene slabs when the facade is not protected with external layers (plastered, painted). An overview of articles collected by different authors on climatic factors and their complex impact is provided. The publication also describes studies of the long-term impact of climatic factors in natural conditions of a facade made from expanded polystyrene slabs that are not protected with any coating. The following properties were studied: tensile strength, compression strength, water absorption; studies of the macro and microstructure were also carried out.
