The possibility of replacing traditional structural materials with polymer composite in the construction and reconstruction of elevator shafts of frame-attached structural solutions has discussed. The experience of using polymer composite materials and traditional materials (steel, aluminum, wood) is investigated as a comparison of their technical characteristics, advantages and disadvantages are given. The purpose of this article is to justify the use of fiberglass-based composite materials in the manufacture of structures and roofs of frame-mounted elevator shafts by comparing the characteristics of polymer composite materials and traditionally used structural materials. In the course of the study, it was found that polymer composite materials based on fiberglass has clear advantages over traditional materials, it is lighter, stronger, more resistant to atmospheric influences, it conducts heat poorly, does not pass water, and fireproof, which confirms the relevance of the chosen research topic.
