Certified Firestopping and Acoustical Sealant Systems for Your Building

At OJ Specialty Contracting, we pride ourselves on being leaders in installing firestop and acoustical sealant systems. We have specialized in providing top-quality firestop products, including firestop sealants, fire-rated joint and through-penetration assemblies, intumescent paint, perimeter fire containment and smoke and fire-rated through penetrations. Our services cater to various sectors, including commercial (storefronts), multifamily housing, hotels, offices, labs, schools and other occupied spaces.

Our extensive knowledge and training, combined with our memberships and certifications from leading manufacturers and third-party organizations, enable us to offer a comprehensive solution to all your firestopping needs.

Why Firestopping Matters

Fire containment is a primary concern for building designers and owners. Controlling fire, smoke and poisonous gases is critical to any structure’s overall life safety plan. Typically, this requires active fire protection systems (like fire sprinklers and alarms) and passive fire protection systems (like firestopping and spray fireproofing). These systems must meet stringent building code requirements governing building design, construction and occupancy.

How Firestopping Works

Firestopping is a passive fire protection approach that compartmentalizes various building components, including fire-rated walls, joints and floors. The goal is to prevent fire spread within a building by properly sealing every fire-rated assembly opening, penetration and joint. This process helps maintain or achieve the designated fire-resistive rating.

Contrary to common belief, firestop materials alone do not have specific fire ratings. Instead, firestop materials are one component of the overall firestop system, tested by organizations like UL (Underwriters Laboratories) or other third-party agencies. The firestop assembly, including all building components, must work together to achieve or maintain the specified fire-resistive rating.

Types of Firestopping and Acoustical Sealant Systems We Offer

Through Penetrations

We specialize in firestopping and acoustical sealing for mechanical, electrical, plumbing and fire sprinkler systems in fire- and sound-rated through penetrations. Our solutions are ideal for commercial storefronts, multifamily housing, hotels, offices, labs, schools and other occupied spaces.

Joint Systems

Our expertise extends to firestopping and acoustical sealing for concrete, masonry and gypsum fire- and sound-rated joint systems. These are crucial for ensuring the integrity of commercial storefronts, multifamily housing, hotels, offices, parking structures and other occupied spaces.

Fire Caulking and Sealants

We offer high-temperature acrylic or silicone sealants used around penetrations such as pipes, doors, or joints between adjoining surfaces to prevent the spread of smoke and gases.

Insulation and Fire Blankets

Made from mineral wool, fiberglass, or high-temperature foam, these materials help prevent the spread of heat and flames through walls, ceilings, or floors.

Mortars

Our mortars, made from gypsum or cementitious materials, seal wall assemblies to concrete floors, between adjoining concrete surfaces and expansion joints in concrete slabs.

Intumescent Coatings

These coatings expand with heat to create an insulating barrier on exposed columns and beams, protecting the surfaces beneath from heat and flames.

Collars

Collars, installed on flues, pipes, ducts and similar assemblies, help contain flames and prevent them from spreading to other areas.

Fire Wrap Blanket

If your business needs a solution for various duct systems, consider our highly effective fire wrap blanket as a firestop. It provides superior fire protection by preventing fire spread through ductwork and maintaining the integrity of these essential pathways during a fire.

• Kitchen exhaust grease ducts carry hot air, smoke, and grease-laden vapors from commercial kitchens. Due to the buildup of grease, these ducts are highly flammable. A fire wrap blanket provides a fire-resistant barrier around the duct, preventing the spread of fire both inside and outside the duct. This is crucial in protecting the building structure and occupants.
• Ventilation ducts circulate air within buildings. If a fire occurs, these ducts can act as pathways for the fire to spread. Fire wrap blankets insulate the ducts, containing the fire within specific areas and preventing it from spreading through the ventilation system.
• Dryer and exhaust ducts can accumulate lint, which is highly flammable. If a fire starts in the dryer or duct, it can quickly spread. Fire wrap blankets around these ducts help contain the fire, preventing it from spreading to other parts of the building.

Endothermic Wrap

Our endothermic wrap is a specialized fire-protection material designed to protect critical systems such as Distributed Antenna Systems (DAS) emergency conduits and fuel piping from high temperatures during a fire. The term “endothermic” refers to a chemical process where the material absorbs heat during exposure to high temperatures, which helps to lower the temperature of the protected items. This property makes the wrap effective at delaying or preventing critical infrastructure failure during a fire.

• DAS emergency conduits: DAS systems are essential for maintaining communication within a building during emergencies, including fires. These systems often include conduits carrying power and communication lines. An endothermic wrap around these conduits helps ensure the system remains operational by absorbing heat and slowing the temperature rise within the conduit, preventing failure or degradation of the cables and components.
• Fuel piping: An endothermic wrap around fuel piping prevents the fuel inside from reaching its ignition temperature by absorbing heat and protecting the pipe’s integrity. This reduces the risk of a catastrophic explosion or fire spreading from an existing blaze.
