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 comprises a core; and a fire retardant included in the core in an amount effective to pass testing mandated by UL 2079. The core with the fire retardant is configured to facilitate compression of the expansion joint system when installed between substrates by repeatedly expanding and contracting to accommodate movement of the substrates; and the core with the fire retardant included therein is configured to pass the testing mandated by UL 2079.

Abstract: A water resistant expansion joint system for installation into a building joint in vertical and horizontal configurations is designed such that it can be used for either an inside or outside corner. According to an aspect, the system comprises open celled foam having a water-based acrylic chemistry infused therein. A layer of an elastomer is disposed on the open celled foam and is tooled to define a profile to facilitate the compression of the expansion joint system when installed between coplanar substrates. The system is delivered to a job site in a pre-compressed state ready for installation into the building joint.

Abstract: A fire and water resistant, integrated wall and roof expansion joint seal system includes an expansion joint seal for a structure. The seal includes a central portion having an underside and at least one central chamber disposed around a centerline, a first flange portion extending outwardly from the centerline and a second flange portion extending outwardly from the centerline in a direction opposite the first flange portion. The system further includes a joint closure. The joint closure includes a core and a layer of a water resistant material disposed on the core. The joint closure further includes an end portion configured to match and integrate with the underside of the central portion to form the watertight, integrated wall and roof expansion joint seal system. A fire retardant material is included in the core in an amount effective to pass testing mandated by UL 2079, and the core with the fire retardant material therein is configured to facilitate compression of the core when installed between the first substrate and the second substrate by repeatedly expanding and contracting to accommodate movement of the first substrate and the second substrate; and the core with the fire retardant material included therein is configured to pass the testing mandated by UL 2079. Movement of one or both of the first substrate and the second substrate causes a response in the central portion to maintain the seal.

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.
