The paper explores the use ofpolycarbonate modular systems in the construction of translucent building envelopsfor sports facilities. Basedonthecomparisonofthelighttransmissionperformance involving the most widely used translucent materials, it is easy to see that they are inferior to nearly all other materials. Certain characteristics of cellular polycarbonate sheets are summarized intabularform depending on the number of layers and the cellular structure. Further emphasis is made on the fact the existing lock connections for assembly of large-scale planar structures are not always consistent with the constructability and occupational safety requirements.
