  • Method of sealing openings in structural components of buildings for controlling the passage of smoke
    Patent number: 5744199
    Abstract: This invention relates to a method of sealing openings in structural components of a building to reduce the amount of smoke which may pass through the opening in the event of a fire. The method comprises filling an opening in a structural component of a building with a support material; applying a coating of a silicone composition over the filled opening and allowing the silicone composition to cure into a continuous elastomeric film having certain properties. These silicone compositions exhibit pseudo plastic rheology which facilitates their application by spraying.
