SpecSeal Composite Sheet is a lightweight, rigid fire resistant panel consisting of an intumescent layer bonded to a galvanized steel sheet reinforced with steel wire mesh covered with aluminum foil. SpecSeal Composite Sheet is designed to seal medium to large size openings with a variety of different penetrants in both fire-resistance rated floors and walls.
When exposed to temperatures in excess of 350 degrees F (177 degrees C), SpecSeal Composite Sheet expands minimum 15x to form a dense insulative char that minimizes heat transfer.
