Description

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 350F (177C), SpecSeal Composite Sheet expands minimum 15x to form a dense insulative char that minimizes heat transfer.

Features

  • Lighter weight for easy handling and fabrication and less hanging weight on walls
  • Less than 1/2 in. the thickness of the traditional composite sheet products
  • Easier to fabricate as it can be cut and installed with common sheet metal tools
  • Higher intumescence expanding up to 15 times when exposed to temperatures in excess of 350F (177C)
  • UL Classified
