SUMMARY
Toughened soda-lime-silicate glass is a popular material widely used in construction due to its very good functional properties, characterised by high strength, safety in use, fire resistance, and also good thermal insulation. In this study, tests were conducted to describe the dependence between the bending strength of ESG toughened float glass and the thickness of the sample, the state of the sample edge, and the application of security film. Tests were also conducted on the influence of the placement of openings used for mounting glass screens used to secure display cases and other objects of a similar nature. The information obtained was used to design glass security screens and a new type of display case, a closed cassette with a glass screen, intended for use in protecting works of art from acts of vandalism and the destructive influence of environmental conditions.
