SpecSeal SIL Self-leveling Silicone Firestop Sealant
SpecSeal® SIL300 SL Self‑Leveling Silicone Sealant is a high‑performance silicone firestop sealant engineered to protect construction joints and through‑penetrations from the spread of smoke, flame, and water. Its self‑leveling formulation ensures smooth, effortless application on horizontal surfaces, making it ideal for slabs, joints, and other large‑format penetrations. Once cured, SIL300 forms a flexible, durable fire‑resistant barrier designed to withstand building movement while maintaining long‑term system integrity. The sealant also carries a Class 1 W Rating for water resistance (ANSI/UL 1479), verifying its ability to prevent water passage —an essential feature for assemblies requiring moisture protection in addition to firestopping. Engineered for demanding commercial, industrial, and high‑rise environments, SpecSeal SIL300 SL delivers reliable, code‑compliant fire, smoke, and water protection in a versatile, self‑leveling silicone formula
Marine Snap-Seal Cable Plugs
Snap-Seal features a split design for easy installation around new or previously installed penetrants, and was specifically designed for small cables and metallic/plastic tubes. This device is ideally suited for use with surveillance cameras, speakers, lights, data cables and hydraulic lines penetrating steel and aluminum divisions.
Marine Wrap Strip
This intumescent wrap strip comes in convenient cut-to-length rolls providing an economical solution for firestopping combustible penetrants. MWS offers a flexible, high-performance option to seal bulkheads and decks by forming an effective barrier against fire, smoke, and hot gasses.
Marine RTV Firestop Foam
This two-component RTV silicone foam features excellent crack-and-void filling capabilities and provides high resilience to accommodate vibration. MRF is designed as a seal for both deck and bulkhead pipe penetrations, which when properly mixed, expands 2 to 4 times its original volume, filling available spaces and forming an effective barrier against fire, smoke, hot gas and water penetration.
SpecSeal Cast-in Device for Large Diameter Pipes
The SpecSeal® 8‑Inch Cast‑In Firestop Device is a fully integrated sleeve and firestopping solution designed to create a clean, ready‑to‑use opening with its convenient removable core. Built with a durable sheet‑metal housing, the device surrounds a high‑performance intumescent firestop and smoke‑sealing system, ensuring reliable protection in concrete floor penetrations. Engineered for versatility, the 8 in. (203 mm) Cast‑In Firestop Device is available in two configurations to accommodate both plastic pipe and metallic pipe penetrants. This makes it an ideal firestopping choice for new construction projects requiring code‑compliant, large diameter penetrations in concrete slabs.
SpecSeal Firestop Block
SpecSeal® Firestop Blocks are high‑performance intumescent penetration firestop solutions engineered to resemble lightweight, easy‑to‑handle foam bricks. Made from durable intumescent urethane foam, these blocks are installed by compressing and stacking them into openings in a brick‑like fashion, creating a clean and efficient firestop seal without the need for caulks, putties, or mineral wool. When exposed to high temperatures, SpecSeal Firestop Blocks rapidly expand, forming a dense, insulating char that helps block the spread of fire, smoke, and hot gases through wall and floor penetrations. Their re‑enterable design makes them ideal for cable tray openings, busways, complex MEP conditions, and blank penetrations. Engineered for versatility and code‑compliant fire protection, SpecSeal Firestop Blocks provide a simple, reusable, and time‑saving solution for both new construction and retrofit applications.
EZ-Path Series 84+ Fire-rated Pathway
The EZ Path Series 84+ Fire‑Rated Pathway is an engineered passive fire‑protection device designed to accommodate high‑density cable installations passing through fire‑rated wall assemblies. The pathway utilizes integrated, self‑adjusting intumescent pads that maintain a constant seal around cables by automatically conforming to variations in cable fill, eliminating the need for manual maintenance or re‑packing. Under elevated temperature or direct fire exposure, the intumescent materials expands forming a dense char, generating a tight seal that mitigates the transmission of smoke, hot gases, and flame through the penetration. This automatic activation ensures the preservation of the barrier’s fire‑resistance rating while supporting continuous cable management operations, including moves, adds, and changes, without compromising system integrity.
