Aspects of the present disclosure relate to modular wall systems, modular wall units, and methods of installing modular wall systems for indoor environments such as medical treatment environments. In one implementation, a first outer panel and a second outer panel are spaced apart from each other to form a window, and a front panel is attached to front surfaces of the first and second outer panels. The front panel is formed of a polymeric material or a composite material, and the front panel includes an aesthetic design thereon.

A panel comprises a board having a front face and a back face. The back face has a first edge and a second edge that is aligned with the first edge. A first set of tabs and a second set of tabs are attached to the back face, the first set of tabs being positioned along the first edge of the back face and the second set of tabs being positioned along the second edge of the back face, each individual tab being oriented transversely to the respective edge and protruding from the respective edge. The positions of the individual tabs on the first edge of the back face are offset from the positions of the individual tabs on the second edge of the back face.

A rectangular or square wall- or ceiling panel is provided, comprising a first profile a first profile on two opposing edges, whereby each such first profile consists of a panel groove, an inner leg on an installation side of a panel and an outer leg on an visible side of a panel, both inner leg and an outer leg confining said panel groove, wherein both said outer legs are longer than said inner legs. A further second profile may be provided on at least one of the other two opposing edges of the panel, said at least one second profile consisting of a recess on the installation side of the panel. The visible side may be a decorative side.

A joiner clip for securing panels to a substrate is provided that includes a sheet of material that has a first portion, a second portion, a first face, and a second face. On the first face, a first anchoring cleat is located in the first portion and a second anchoring cleat is located in the second portion. A spaced guide is positioned between the first portion and the second portion of the sheet on the first face. A mounting hole is formed through the sheet and is positioned colinear with the spacer guide. A fastener from the second face secures the joiner clip and panels to a vertical stud substrate. A construction unit including the joiner clip for securing panels of material to a vertical stud substrate is also provided. A butt joint is readily formed between two secured panels.
