First Claim
Patent Images
1. A fire and water resistant expansion joint system, comprising:
- a core;
a fire retardant in the core; and
a water resistant layer disposed on the core;
wherein the water resistant layer facilitates compression of the expansion joint system when installed between substrates, and the core with the fire retardant therein when compressed has a density of about 160 kg/m3 to about 800 kg/m3; and
wherein the expansion joint system is angled around a corner, and the fire and water resistant expansion joint system and the core with fire retardant therein are configured to pass testing mandated by UL 2079.

Abstract
A fire and/or 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. The system comprises a core having a fire retardant therein. A layer of a water resistant material is disposed on the core to facilitate the compression of the expansion joint system when installed between substrates. The system can be delivered to a job site in a pre-compressed state ready for installation into the building joint.
