INCA-INSS1440 Fire Barrier Caulk | Firestop
INCA INSS1440 Firestop
High-Performance Acrylic Firestop Sealant
INSS1440 Fire Barrier Caulk is a high-performance, acrylic-based firestop sealant designed to seal gaps around cable penetrations, pipes, fire-rated walls, floors, ceilings, and fire doors.
- A high-performance, acrylic-based firestop sealant designed to seal gaps around cable penetrations, metal pipes, conduits, fire-rated walls, floors, ceilings, and fire doors. It helps prevent the spread of fire, smoke, and hot gases, maintaining the integrity of fire-rated assemblies for up to 3 hours.
- This one-component, gun-grade sealant is water-based, non-sag, and ready to use, ensuring quick and easy installation on both vertical and horizontal surfaces. During a fire, it forms a durable insulating char that enhances fire protection.
- Free from halogens and asbestos, it is also paintable after curing and suitable for a wide range of commercial and industrial applications. INSS1440 maintains its firestop performance even in high-radiation environments, making it ideal for specialized facilities.
- ARACO (Arabian Arrow Supply and Services Co. Ltd.) is an authorized distributor of INSS1440 Fire Barrier Caulk in Saudi Arabia, providing certified passive fire protection solutions for commercial buildings, industrial facilities, data centres, healthcare, oil & gas, power generation, and infrastructure projects.

Technical Specification of INCA INSS1440 Fire Barrier Caulk | Firestop
INSS1440 is versatile
Applications
Electrical Penetrations:
Sealing gaps around cables and conduits to prevent fire spread.
Mechanical Penetrations:
Ideal for sealing around pipes and ductwork
Wall and Floor Joints:
Ensuring firestopping in expansion joints and other structural gaps.
Fire-rated door perimeter sealing:
Fills gaps around fire-rated door frames to maintain the integrity and performance of fire doors during a fire.
Commercial, Industrial, and Infrastructure Projects
Suitable for offices, factories, warehouses, airports, educational facilities, and other projects requiring certified passive fire protection.
Data Centres, Hospitals, Power Plants, and Oil & Gas Facilities
Ideal for critical facilities where reliable firestopping is essential to protect vital equipment, services, and occupants while ensuring compliance with fire safety standards.
Benefits of INCA Firestop
Acrylic-Based Composition
The acrylic base ensures strong adhesion to a wide range of substrates.
It provides flexibility, allowing for movement within the sealed joints without compromising the seal’s integrity.
Fire Rating
INSS1440 offers a fire rating of up to 3 hours.
This means that in the event of a fire, the caulk can effectively prevent the spread of flames and smoke through sealed gaps for this duration, providing critical time for evacuation and fire response
Radiation Resistance
One of the standout features of INSS1440 is its resistance to high levels of neutron and gamma radiation. It can withstand exposure to 1×10^6 Gy (1×10^8 rad) without losing its firestop capabilities.
This makes it suitable for use in environments with high radiation levels, such as nuclear power plants and research facilities.
