STI Firestop SpecSeal® Composite Sheets

• Panels are intumescent up to 15 times their original size for excellent firestopping of large or small openings.
• Once activated, these sheets form a dense insulated char, which reduces the transfer of heat and smoke.
• 50% lighter in weight and approximately 1/2 the thickness of standard composite sheet products for easy installation and handling.

These products protect openings of any shape in common construction work against fire, smoke, and combustion by-products. Another benefit to this type of firestop is that no maintenance is needed as there might be with other choices; however, it is recommended that any new openings or jobs be inspected to ensure that all remained sealed.

• Durability built in: made of an intumescent layer bonded to a galvanized steel sheet, reinforced with steel wire mesh and covered with aluminum foil.
• Easy to cut using standard sheet metal cutting tools to size your composite sheets to specs.
• Can be used with other SpecSeal® or EZ Path products by STI
