Metacaulk® Firestop Sealants

BlazeSeal™ creates a firm seal that prevents the flow of hot smoke, gases, and flames through the door-to-frame clearance of single or double-leaf doors by forming a fire barrier around the perimeter.Compared to other brands, BlazeSeal™ exhibits greater intumescence by expanding to 18 times its original size which allows for more flexibility in the placement of the strip and aids in passing tests of longer duration.BlazeSeal™ may be used with standard door and frame designs. A high degree of expansion allows for flexibility in the placement of BlazeSeal


Metacaulk® BlazeSeal™ is available in a broad range of standard widths, lengths And thickness as well as custom sizes.
