Description
STI Firestop Composite Sheet
Lightweight, easily fabricated panels surface mount to walls and floors to provide a neat, clean firestop seal for medium to large openings with a variety of penetrants in fire-rated floors and walls.
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 up to 15 times to form a dense insulative char that minimizes heat transfer.
Features
Features:Lighter and thinner – approximately 1/2 the weight and thickness of traditional composite sheet Easier to fabricate – engineered with the installer in mind Can be cut and installed with common sheet metal tools Intumescent – expands up to 15 times when exposed to temperatures in excess of 350°F (177°C) compared to 8-10 times for competing brands. Forms a dense insulative char that minimizes heat transfer Hole reduction – reduces large openings when used in conjunction with other SpecSeal® or EZ-Path® Firestop Products Acoustically tested – reduces sound transmission
Common Applications: Medium to large openings through common constructions Single or multiple cable trays for power, voice, data Multiple metallic conduits & tubing Multiple mixed penetrants of many types Suitable for clean room/area environment Combine with the EZ-PATH® System for cable penetrations through large openings Insulated metallic pipes Blank openings Plastic pipes Metal pipes Bus ducts
