An expansion joint system includes a cover plate; a spline attached to the cover plate; and foam having a fire retardant material included therein in an amount effective to pass testing mandated by UL 2079. The spline depends from the cover plate and is configured to be positioned in a gap between substrates such that the cover plate overlies the gap. The foam is compressible between a first face of the spline and one of the substrates and the foam is compressible between a second face of the spline and the other of the substrates, and the expansion joint system is configured to facilitate compression of the foam when installed between the substrates by repeatedly expanding and contracting to accommodate movement of the substrates; and the foam with the fire retardant material included therein is configured to pass the testing mandated by UL 2079.

A flame-retardant composition has a plurality of particles with at least one porosity therein, a flame retardant gas occupying the porosity, and a matrix material in which said particles are dispersed. A sealant applied to at least a portion of the particles, wherein the sealant substantially prevents the gas from escaping the porosities. The matrix is a flame-retardant composition adapted to be applied to various surfaces. The matrix may also function as the sealant. The sealant is formed of a material that will break down and release the gas in the presence of water or flame or other selected conditions. The sealant may be a polymer material. This solves the problem of applying flame-retardant qualities to various surfaces.

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.
