A wall module assembly usable to make interchangeable scenery, the module comprising a first support member having a first end, a second end, a first main surface, and a second main surface, a second support member having a first end, a second end, a first main surface, and a second main surface, a plurality of panel members interchangeably and removably supported by at least one of the first support member and the second support member, adjacent at least one of the first main surface and the second main surface of the first and/or second support member, and a plurality of connection members supported by the first end of the first support member and configured to be removably received within openings formed in the second end of the second support member positioned adjacent to the first support member.

The invention comprises a product. The product comprises a first foam panel having an edge, a first primary surface and an opposite second primary surface and a second foam panel having an edge, a first primary surface and an opposite second primary surface, wherein the first and second foam panels are disposed such that their edges are adjacent each other and define a joint therebetween. The product also comprises an elongate metal strip having a body portion and a projection extending outwardly from the body portion, the metal strip being disposed such that at least a portion of the projection is disposed in the joint between the foam panels and at least a portion of the body portion covers a portion of the second primary surface of the first foam panel and a portion of the second primary surface of the second foam panel. A method of making and using the composite panel is also disclosed.

The disclosure provides a heat insulation wall, and a manufacturing method and a mounting method thereof. The heat insulation wall includes at least one layer of panel, at least one layer of bottom plate and at least one layer of heat insulation board, wherein the panel and the bottom plate are connected through at least one partition body, and the heat insulation board is arranged between the panel and the bottom plate and is maintained by the partition body; the partition body includes a partition body head connected with the panel and a partition body tail connected with the partition body head and the bottom in a partition manner.

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.
