About this item

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.

  • Lightweight for easy handling and fabrication and less hanging weight on walls

  • Highly intumescent – expands up to 15X
  • Hole Reduction - Used in conjunction with other SpecSeal® or EZ-PATH® Products for reducing large openings
