Duct Wrap Fire Protection

Duct Wrap Fire Protection for Commercial Grease Duct Systems

Fire protection for grease ducts is one of the most important safety requirements in any commercial kitchen. Whether you operate a restaurant, hotel, cafeteria, food‑service facility, or industrial kitchen, your ventilation system must be protected with materials that meet strict fire‑rating standards. Our duct‑wrap fire‑protection products are designed to deliver dependable thermal resistance, help prevent fire spread, and support full compliance with city, state, and national fire codes.

A grease duct carries extremely hot air and flammable vapors from cooking equipment to the exterior of the building. Without proper insulation and fire‑rated protection, the duct can become a major hazard. Our fire‑wrap systems provide a lightweight, durable, and code‑compliant solution that helps safeguard your building, your staff, and your customers.

Insulated Fire Duct Wrap

We supply high‑performance reflective duct‑wrap insulation engineered to reduce heat transfer and maintain stable temperatures around the duct. This multi‑layer material is commonly used for thermal control, but when applied in multiple layers, it also provides the fire‑resistance levels required for commercial grease‑duct protection. The result is a reliable, inspector‑approved system that supports safe operation and long‑term performance.

Why Fire‑Rated Duct Wrap Is Essential

Commercial kitchens generate intense heat, airborne grease, and combustible vapors. As these materials move through the duct system, the duct walls can reach extremely high temperatures. If the duct is not properly protected, heat can transfer into surrounding building materials, increasing the risk of ignition and structural damage.

Fire‑rated duct wrap plays a critical role in preventing these hazards. It helps:

• Limit heat transfer through the duct walls
• Contain potential fire inside the duct
• Protect nearby framing, insulation, and building components
• Maintain safe operating temperatures
• Support compliance with NFPA standards and local fire codes
• Ensure smooth, successful inspections

Because grease ducts are often routed through walls, ceilings, and tight mechanical spaces, the fire‑wrap system must be flexible enough to conform to corners and transitions while still providing continuous protection. Our duct‑wrap products are engineered specifically for this type of installation, offering both performance and ease of use.

How Our Duct Wrap Fire‑Protection System Works

Our fire‑rated duct wrap is built from multiple layers of reflective foil and air‑cell insulation. This construction creates a thermal barrier that slows heat transfer and helps maintain the required fire‑resistance rating. Each layer of the wrap provides approximately one hour of thermal protection, allowing installers to build the level of fire resistance needed for the project.

Most commercial grease‑duct applications require a 2‑hour fire rating. To meet this requirement, the wrap is applied in two complete layers around the duct system. When installed correctly, the double‑layer configuration provides the equivalent of two hours of fire‑resistance performance, helping the duct meet inspection standards and pass code requirements.

The installation process typically includes:

• Wrapping the duct with the first layer of insulation, ensuring full coverage
• Securing the material with approved fasteners or tape
• Applying a second full layer to achieve the required fire rating
• Maintaining proper overlap and continuity around corners, joints, and transitions
• Ensuring the wrap remains tight and uniform for consistent thermal protection

Because the material is lightweight and flexible, it can be installed quickly and efficiently, even in tight mechanical spaces or vertical shafts. This helps reduce labor time while still delivering a high‑performance fire‑protection system.

Key Benefits of Our Fire‑Rated Duct Wrap

Our duct‑wrap insulation is engineered to provide dependable performance in demanding commercial environments. It offers several advantages over traditional fire‑protection methods:

• Lightweight construction — Easy to handle, transport, and install, even in confined spaces.
• Durable multi‑layer design — Resistant to tearing and damage during installation.
• Reflective thermal barrier — Helps limit heat transfer and maintain stable temperatures.
• Flexible application — Conforms to bends, offsets, and transitions without compromising coverage.
• Code‑compliant performance — Multiple layers can be applied to meet 1‑hour, 2‑hour, or project‑specific fire‑rating requirements.
• Energy‑efficient properties — Helps reduce heat loss and improve overall duct performance.
• Versatile use cases — Suitable for restaurants, commercial kitchens, food‑processing facilities, and any building requiring grease‑duct fire protection.

Because the material is designed for both thermal control and fire‑resistance performance, it provides a dual benefit: improved energy efficiency and enhanced safety.

Meeting Fire‑Safety Codes and Inspection Requirements

Commercial kitchens must comply with a range of fire‑safety standards, including NFPA 96, local building codes, and city or state inspection requirements. These regulations are designed to ensure that grease ducts are properly protected and that fire cannot spread through the ventilation system.

Our duct‑wrap fire‑protection products help meet these requirements by providing:

• A tested and proven method for achieving required fire ratings
• A continuous thermal barrier around the entire duct system
• A lightweight alternative to traditional fire‑rated enclosures
• A solution that supports both new construction and retrofit projects

Because each layer of the wrap provides approximately one hour of fire protection, installers can easily build the level of resistance needed for the project. This flexibility makes the system suitable for a wide range of commercial applications, from small restaurants to large industrial kitchens.

Designed for Performance and Practicality

In addition to meeting fire‑safety requirements, our duct‑wrap insulation is designed to support long‑term performance. The reflective foil surface helps limit heat transfer, reducing temperature fluctuations inside the duct. This can improve airflow efficiency and help maintain consistent ventilation performance.

The material is also engineered to withstand the demands of commercial environments. It resists moisture, tearing, and compression, helping maintain its protective properties over time. Because it is lightweight and easy to handle, it reduces installation time and labor costs compared to heavier, more rigid fire‑protection systems.

For contractors, this means faster installation and fewer complications. For building owners, it means a reliable, code‑compliant fire‑protection system that supports safe operation and long‑term durability.

A Reliable Solution for Commercial Kitchens

Whether you are building a new commercial kitchen, upgrading an existing ventilation system, or preparing for inspection, our duct‑wrap fire‑protection products offer a dependable solution. The multi‑layer design provides the fire‑resistance performance required by modern building codes, while the lightweight construction makes installation straightforward and efficient.

Our duct wrap is suitable for:

• Restaurants and commercial kitchens
• Hotels and hospitality facilities
• Schools and institutional kitchens
• Food‑processing plants
• Industrial ventilation systems
• Any building requiring grease‑duct fire protection

By choosing a high‑quality fire‑rated duct wrap, you help ensure that your ventilation system operates safely, efficiently, and in full compliance with fire‑safety standards.
