a frame assembly including at least one vertical frame member and at least one horizontal frame member, wherein the frame assembly is configured to define a door opening;
a door member slidably supported on the frame assembly between a closed position, wherein the door member is at least partially located within the door opening, and an open position, wherein the door member is at least partially removed from within the door opening to allow ingress and egress through the door opening;
a trim member coupled to the at least one vertical frame member, the trim member including an outwardly opening channel disposed adjacent to the door member when the door member is in the closed position;
a seal member having a first portion coupled to the outwardly opening channel of the trim member, and a second portion, wherein the second portion is spaced apart from an inner surface of the door member as the door member moves between open and closed positions; and
a trim strip coupled to the inner surface of the door member and extending inwardly from the inner surface of the door member towards the trim member, wherein the second portion of the seal member seals against the trim strip when the door member is in the closed position.

### Claim 2 (depends on 1)

The modular wall assembly of claim 1, wherein the first portion of the seal member includes one or more tabs configured to engage the outwardly opening channel of the trim member.

### Claim 3 (depends on 1)
