A fire resistant gasket for architectural joints comprises an intumescent material mat having a first major surface and a second major surface, wherein at least one of said first and second major surfaces has coated thereon an adhesive. A fire barrier is provided comprising: at least one fire resistant intumescent gasket material having a first major surface and a second major surface, wherein at least one of said first and second major surfaces has coated thereon an adhesive, and at least one fire resistant material barrier layer bonded to a portion of one of said first and second major surface, preferably adhered to a portion of said adhesive coated gasket surface. A process for installing a building joint fire barrier comprises providing at least one fire resistant intumescent gasket material having a first major surface and a second major surface, wherein at least one of said first and second major surfaces has coated thereon an adhesive, adhering the gasket material to at least one of a building member and a fire resistant material barrier layer, and affixing the fire resistant material barrier layer to the building member with the gasket material interposed therebetween.
