Flexible, precured dry intumescent strips installed as an integral part of fire door assemblies to provide a positive pressure seal in the clearance area between the door and frame, at the assembly threshold, through hardware such as closers and locks, or in frame assemblies utilizing fire-rated glass in both doors and side lites.

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
