SpecSeal Composite Sheet Assembly 36" x 36"

The 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°F (177°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
• Easy to cut using sheet metal tools
• Highly intumescent - expands up to 15x
• Hole reduction - used in conjunction with other SpecSeal or EZ-Path products for reducing large openings
• Versatile performer for a wide range of complex applications
• Paintable

Applications

• Blank Opening
• Busway
• Cables
