3 in. SpecSeal® Cast-In Firestop Device for Combustible and Non-Combustible Penetrants | STI-CD302C

STI's 3 in. SpecSeal® Cast-In Firestop Device for Concrete Floors is designed for efficient installation in concrete floor assemblies where reliable fire, smoke, and water resistance are required around penetrating services. The permanent, intumescent device is engineered to expand when exposed to elevated temperatures and is tested to recognized firestop standards including ASTM E814 and CAN/ULC-S115. By incorporating the firestop function into the cast-in assembly, the device can help reduce labor and eliminate the separate firestopping step that would otherwise follow concrete placement.

• Accommodates 3 in. trade-size penetrants through concrete floor assemblies up to 20 in. thick
• Combines a sleeve, concrete form, and firestop system into a single cast-in device
• Built-in smoke- and water-resistant sealing helps protect the penetration
• Tested for use with both combustible and non-combustible penetrants
• Intumescent firestop technology expands when exposed to elevated temperatures to help maintain the protected penetration
