This duct wrap is designed as a lightweight, space-saving alternative to traditional shaft enclosures for grease ducts. It’s suitable where a two-layer installation is possible and supports custom configurations with multiple layers. Best for facilities seeking a proven fire-rated barrier without bulky enclosures. Use caution: verify compatibility with duct dimensions and local codes before selecting a multi-layer approach.

This 1.5 inch thick fiberglass blanket is rated to withstand up to 1000°C, making it a strong option for high-heat grease ducts in commercial kitchens. It provides full 360-degree duct encasement to minimize gaps and improve thermal protection. Best for kitchens with very hot exhaust lines or where a comprehensive wrap is required. Limitation: due to heat tolerance, placement should consider long-term exposure and edge conditions to avoid insulation compression over time.

Designed for larger grease duct runs, this roll provides longer spans with fewer seams, expanding the practical reach for larger kitchens. It remains UL and Intertek certified, meeting key life-safety codes. Best for facilities needing higher coverage with fewer connection points. Choose this if duct length or space reduces the number of rolls required; avoid if you have very tight installation areas where maneuverability is limited.

This option mirrors the 3M duct wrap’s space-saving approach and is positioned as an alternative to shaft enclosures for grease ducts. It’s best for projects wanting to apply in two layers and still maintain a clear, efficient install. A limitation to consider is whether the available duct dimensions support a clean, two-layer wrap without gaps or overlaps.

This eight-pack provides bulk convenience for large facilities or ongoing maintenance programs. Best for operators who want steady supply for multiple grease duct runs. It’s a straightforward choice when consistency and long-term planning are priorities. Caution: verify that the installation space accommodates rolled material storage and that roll selection aligns with duct dimensions to minimize waste.

Buying Guide: Key Considerations For Grease Duct Fire Wrap

What fire rating do you need? Look for products with up to two-hour fire resistance and approvals from UL, Intertek, or equivalent authorities. Higher ratings are essential for larger ducts or spaces with stricter code requirements.

What duct size and length are you wrapping? Select rolls that minimize seams for smoother coverage. Larger rolls reduce the number of necessary joints but may be harder to maneuver in tight areas.

Two-layer versus single-layer installations: Some ducts require multiple layers to meet the safety standard. Plan the installation sequence to ensure complete wrap around the duct with no exposed gaps.

Material and temperature performance: Fiberglass wrap and inorganic fiber blankets perform differently under heat. For very hot exhausts (close to 1000°C), choose a product with robust heat barrier properties and full 360-degree encasement.

Code compliance and testing: Verify that the product is tested against recognized standards (e.g., NFPA, ASTM) and rated for grease duct installations as required by your building codes and local authority having jurisdiction.

FAQ

  1. What is grease duct fire wrap? It is a fire-resistant lining applied around grease ducts to slow fire spread and provide thermal protection in commercial kitchens.
  2. Why choose a two-layer wrap? A two-layer approach improves fire resistance and can meet stricter code requirements for grease ducts.
  3. Can I use duct wrap on all duct shapes? Most wraps are designed for round or rectangular ducts; ensure the product covers corners and irregularities effectively.
  4. Is UL certification required? Certification helps ensure compliance with life-safety codes; verify approvals for your project.
  5. How do I know which size to buy? Measure duct diameter and check the roll length to minimize seams and waste.
  6. Do these wraps affect airflow? Proper installation should not impede airflow; avoid excessive bulk at turns or junctions.
