Abstract
Abstract A portable insulation blanket made of flame resistant materials for protecting concrete surfaces. The blanket has a flame resistant core having a plurality of layers of insulating structures. Each layer of insulating structure has a plurality of closed cell portions defining gas containing chambers. A cover of flame resistant plastic sheet material encloses the core. The cover has edges that are stitched or welded together. A plurality of holding assemblies are mounted on the cover and project through the core to hold the core in a flat position between the covers.
