Abstract
A fire and water resistant expansion joint system has a cover plate; a spline attached to the cover plate along a first edge of the spline; and two portions of foam, each portion being located on an opposing face of the spline. The foam has a fire-retardant material infused therein. The spline depends from the cover plate and is positioned in a gap between substantially coplanar substrates such that the cover plate overlies the gap. Each portion of the foam is compressed between a respective face of the spline and a face of one of the coplanar substrates.

A fire and water resistant expansion joint system, comprising:
- a cover plate;
- a spline attached to the cover plate along a first edge of the spline;
- a first foam having a fire-retardant material infused therein located on a first face of the spline;
- a second foam having a fire-retardant material infused therein located on a second face of the spline;
- wherein the spline depends from the cover plate and is positioned in a gap between substantially coplanar substrates such that the cover plate overlies the gap;
- and
- wherein the first foam is compressed between the first face of the spline and one of the coplanar substrates and the second foam is compressed between the second face of the spline and the other of the coplanar substrates, and the fire and water resistant expansion joint system is capable of withstanding exposure to a temperature of about 540° C. or greater for about five minutes.
