Abstract

Aspects of the present disclosure relate to modular wall systems and methods of installing modular wall systems in hygienic environments. In one aspect, gap cover apparatus are disclosed. In one aspect, backplate arrangements are disclosed. In one aspect, non-progressive installation methods are disclosed. The modular wall systems can eliminate protruding ledges while maintaining structural integrity and hygienic properties.
