Our fire stopping systems are designed to contain fire and smoke by sealing service penetrations, construction joints, and other openings in fire-rated assemblies. These systems are essential for compartmentalization, helping limit fire spread and protect escape routes in case of emergency. Applied in a wide range of environments—from high-rise buildings to healthcare facilities—our fire stopping solutions comply with stringent international safety standards. We ensure precise application and material compatibility to maintain the fire-resistance rating of building envelopes, supporting architects, engineers, and contractors in delivering safe, code-compliant structures.
Firestop sealants are specially formulated materials designed to seal gaps and penetrations in fire-rated walls and floors. Available in intumescent and silicone-based types, they expand under heat to block fire, smoke, and toxic gases. Ideal for sealing around pipes, cables, and ducts, these UL-listed sealants maintain the integrity of fire barriers. Intumescent sealants swell to fill voids during fire, while silicone-based variants offer superior flexibility and moisture resistance. Both meet ASTM E814 and UL 1479 standards, ensuring code-compliant, long-lasting firestop protection in commercial and industrial applications.
Firestop putty is a moldable, intumescent firestopping solution used to seal electrical boxes, cable penetrations, and irregular openings in fire-rated assemblies. Available as pads or sticks, firestop putty expands when exposed to heat, creating a fire-resistant seal that blocks flames, smoke, and gases. It’s ideal for retrofitting and tight spaces where traditional firestop products are hard to apply. Firestop putty complies with UL 1479 and ASTM E814 standards and is frequently used in data centers, schools, and commercial buildings to maintain passive fire protection integrity.
Firestop mortar is a lightweight, cementitious fire barrier used to seal large openings around cables, pipes, and conduits in fire-rated walls and floors. It provides a robust, non-shrinking firestop solution that resists high temperatures and smoke transmission. Firestop mortars are easy to apply, durable, and compatible with other firestop systems. They are tested to UL 1479 and ASTM E814 standards, delivering fire ratings of up to 4 hours. Ideal for electrical riser rooms, mechanical shafts, and commercial fire-rated assemblies requiring long-term protection.
Intumescent firestop collars are specialized devices designed to encircle plastic pipes penetrating fire-rated walls and floors. In a fire event, the collar’s intumescent material rapidly expands, crushing and sealing the melting pipe to block flame and smoke spread. These UL-listed collars are ideal for PVC, CPVC, and ABS piping in residential, commercial, and industrial buildings. Easy to install and tested to UL 1479 and ASTM E814, intumescent firestop collars are a reliable, code-compliant solution for maintaining fire resistance at pipe penetrations.
Intumescent wraps and strips are flexible, fire-resistant materials that expand under heat to seal pipe and cable penetrations. Ideal for use around plastic pipes, insulated metal pipes, and bundled cables, they prevent the spread of fire, smoke, and toxic gases through fire-rated assemblies. These wraps are used alone or in conjunction with firestop collars and sleeves. Intumescent wraps comply with UL 1479 and ASTM E814 standards and are suitable for a variety of construction applications where space or configuration requires a flexible, high-performance firestop solution.
Firestop foam is a polyurethane-based, expanding firestop material designed to seal annular spaces around mechanical, electrical, and plumbing penetrations. It expands to fill irregular gaps, providing up to 2-hour fire resistance while also blocking smoke and toxic gases. This UL-listed foam is ideal for sealing pipes, cables, and conduit penetrations in concrete and gypsum assemblies. It complies with ASTM E814 and UL 1479 standards and offers fast application, excellent adhesion, and long-term performance in commercial, institutional, and industrial settings.
Firestop pillows are compressible, intumescent blocks designed for temporary or permanent sealing of large cable trays, conduit banks, and floor openings in fire-rated assemblies. They expand under fire exposure to fill voids, maintaining the fire barrier integrity. Firestop pillows are UL-tested and ideal for locations requiring frequent access for maintenance or re-entry. They comply with ASTM E814 and UL 1479 standards and provide flexible, non-messy firestop solutions for data centers, utility rooms, and other critical infrastructure requiring both fire protection and reusability.
Firestop sleeves are factory-assembled devices used to protect penetrations through fire-rated walls and floors, primarily for cable bundles or conduit runs. These sleeves integrate intumescent technology that expands to seal around cables during fire, preventing flame and smoke spread. Ideal for clean installations and areas requiring future cable changes, firestop sleeves are UL-listed and comply with ASTM E814. Their modular design allows for quick, code-compliant installation, making them perfect for IT rooms, data centers, and commercial buildings with high cable density.
Firestop gaskets and pads are pre-formed, intumescent materials used to maintain fire ratings around electrical outlet boxes and other wall penetrations. Installed behind electrical boxes, they expand when exposed to heat, sealing the box to prevent fire and smoke spread. These products are ideal for multi-family dwellings, schools, and healthcare facilities where code compliance and fire safety are critical. Firestop gaskets and pads meet ASTM E119, E814, and UL 263 standards, offering a clean, reliable alternative to messy sealants or putties.
Firestop composite sheets are multi-layered firestop materials made of steel foil, intumescent compounds, and insulation. Designed to seal large openings with multiple penetrants such as cables, pipes, and ducts, they provide up to 4-hour fire resistance. Composite sheets are easy to cut and install, offering high-performance fire, smoke, and acoustic sealing in a compact form. UL-listed and tested to ASTM E814, they are ideal for utility rooms, telecom facilities, and industrial firestop applications requiring maximum protection with minimal space usage.
Fire-rated boards made from mineral wool or calcium silicate are rigid panels used to construct firestop barriers and enclosures around mechanical services, ducts, and structural steel. These non-combustible boards resist temperatures up to 1000°C and provide 1- to 4-hour fire ratings. They are ideal for fire-rated partitions, cable enclosures, and HVAC duct firestopping. Compliant with ASTM E119 and EN 1366-3, fire-rated boards offer excellent mechanical strength, moisture resistance, and long-term stability for high-performance passive fire protection in commercial and industrial buildings.
