  • In situ molded thermal barriers
    Patent number: 6783345
    Abstract: The invention provides methods, systems, and devices for installing barriers in openings or gaps in or between structures such as walls, ceilings, and floors. At least one barrier molding bag is positioned in the hole or gap, and a flowable firestop material that is preferably operative to cure or harden, such as a hydratable cementitious slurry, is introduced into the bag to create a barrier in the hole or gap.
