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.
