Light and thin, the STI firestop composite sheet available from Discount Low Voltage has about half the weight and thickness of traditional composite sheets. That makes this product easy to work with. You can cut and install it with common sheet-metal tools. Easy to cut and fabricate, these fabric sheets provide neat, clean firestop seals for medium to large openings with many penetrants in fire-rated floors and walls.
This rigid, fire-resistant panel is tough. It has an intumescent layer bonded to a galvanized steel sheet reinforced with steel wire mesh covered with aluminum foil. At temperatures above 350 degrees Fahrenheit, the sheet expands up to 15 times to minimize heat transfer. That compares to eight to 10 times for other brands.
This STI composite sheet is suitable for many applications. It is ideal for medium to large openings through common constructions, single or multiple cable trays for power, voice and data, multiple mixed penetrants of many types, metal and plastic pipes and many other uses. It also can be combined with the EZ-Path system for cable penetrations through large openings. We offer composite sheet in assorted sizes, including:
