Abstract
An intumescent fire protection barrier in the form of an adhesive sheet or continuous roll of tape. The barrier comprises laminated layers of an intumescent material, a reinforcing matrix, a pressure sensitive adhesive and a release liner. The intumescent material is adhesively applied to a structural steel substrate and expands by at least 10 times its original thickness during a fire to provide fire protection to the substrate. Multiple layers of the fire protection barrier may be installed on top of one another. This application method dramatically reduces installation time as compared with sprayed on fire protection coatings.
