The aim of the publication is a preliminary analysis of the strategy of creating a message in architecture with a glass facade as the carrier. Several examples will present: ways of creating an image language using a metaphor and the use of visual codes in creating specific content. Repeated plastic treatments related to the construction of the image, and characteristic of facade art glass, will be analyzed. Their impact on the strength of the message will be analyzed. The collected material includes realizations of various themes and pictures. Among 30 projects, representative glass projects were distinguished, in which the authors use metaphor as one of the forms of expression. The metaphor was used in the text, figurative material, abstraction. Intermediate forms existing between the above-mentioned groups were noticed, i.e. a figurative image made of lettering elements, an abstract image created in figurative elements. The analysis was made in five sections. Due to the global nature of plastic phenomena, there is no limited area of research.
