    Abstract: 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.

    Abstract: A fire resistant and water resistant expansion joint system comprises a compressed lamination of fire retardant infused open celled foam, one coat of an elastomeric waterproofing or water resistant material on the lamination, and another coat of an intumescent material on an opposing surface of the lamination, thereby providing fire resistance in one direction and water resistance in the opposite direction. The intumescent material may be further coated with a similar elastomeric material, thereby providing fire resistance in one direction and water resistance in both directions. In the alternative, the compressed lamination may comprise first and second opposing layers of intumescent material thereon each having a respective layer of elastomeric material to provide both water resistance and fire resistance in both directions.

    Abstract: An expansion joint system includes a cover plate; a spline attached to the cover plate; and a core 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 core is compressible between a first face of the spline and one of the substrates and 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 core when installed between the substrates by repeatedly expanding and contracting to accommodate movement of the substrates; and the core with the fire retardant material included therein is configured to pass the testing mandated by UL 2079.

    Abstract: A water resistant expansion joint system includes foam, which has been formed into a desired shape by at least one of stamping, cutting, molding and die-cutting; and a layer of an elastomer disposed on the foam. The layer of the elastomer facilitates compression of the water resistant expansion joint system when installed between substrates. The desired shape of the foam includes an angle, and the water resistant expansion joint system is angled around a corner and accommodates thermal and seismic movement in the system by expanding and contracting, and creates a waterproof seal around the corner upon expansion of the foam between the substrates.

    Abstract: A fire and water resistant expansion and seismic joint system has a cover plate; a spline attached to the cover plate along a first edge of the spline; and a core comprising a first core portion and a second core portion, each portion being located on an opposing face of the spline. The first core portion and the second core portion have a fire-retardant material infused therein. The spline depends from the cover plate in a one piece construction and extends into the core to a depth within the core, and is positioned in a gap between substantially coplanar substrates such that the cover plate overlies the gap. Each portion of the core is compressed between a respective face of the spline and a face of one of the coplanar substrates.
