3M Fire Barrier Duct Wrap 615+, 24 in x 25 ft
Features include a proven alternative to traditional shaft enclosures for grease ducts, with a lightweight, thin profile that eases installation and saves space. It supports multiple layers where needed and uses a butted inner layer in 2-layer grease duct applications. Best for projects requiring lightweight, adaptable fire resistance and easier handling in tight spaces. Caution: verify compatibility with duct configurations that need dual-layer protection.
3M Fire Barrier Duct Wrap 615+, 48 in x 25 ft
Best for larger ducts needing robust protection recognized by UL and Intertek. It protects both grease and air ducts and is certified to key life safety codes, including ASTM E2336 and ISO 6944. It provides fire resistance for up to 2 hours and uses an inorganic fiber blanket encapsulated with a scrim-reinforced foil. Choose this when regulatory compliance and a higher duration rating are critical. Caution: heavier roll may require more handling and cutting precision.
FyreWrap Elite 1.5 Duct Insulation – 24×25
ASTM E2336 certified for grease duct applications, providing a fire barrier with ample coverage on large ducts. The roll size (24×25) supports efficient installation for sizable duct runs. Best for kitchens and industrial settings where grease duct fire protection is essential. Caution: ensure surface preparation aligns with installation guidelines for maximum performance.
Sasylvia Fire Rated Duct Wrap 1.5″ 24×17′
Designed to withstand extreme heat up to 1000°C, this fully encapsulates ducts for complete thermal protection. Its full 360-degree coverage helps minimize gaps where fire can spread. Best for high-heat grease ducts in demanding commercial kitchens. Limitation: larger ducts may require multiple wraps for complete coverage.
US Energy Products R-8 Duct Wrap 4×25
Offers double-sided reflective insulation with a heavy-duty scrim. It is Class 1 / Class A fire rated and ASTM certified, meeting fire code requirements. Best for applications needing a reflective barrier in addition to a fire-rated wrap. Caution: ensure compatibility with existing reflective insulation layers and duct materials.
Buying Guide
What should you consider when choosing fire rated duct wrap?
- Fire rating and code compliance: Look for products certified to ASTM E2336, ISO 6944, and local codes. A higher rating (up to 2 hours) may be required for certain installations.
- Application type: Grease ducts vs. air ducts, single-layer vs. multi-layer installations, and whether a complete 360-degree wrap is needed.
- Roll size and coverage: Larger ducts need longer rolls; verify width and length match your duct dimensions to minimize wastage.
- Weight and handling: Lightweight options ease installation in tight spaces, while heavier products may require additional support.
- Material composition: Inorganic fiber, fiberglass blankets, and reflective foam cores offer different thermal performance and moisture resistance.
- Installation notes: Some products require inner layers or scrim reinforcement; check for compatibility with double-layer ducts and grease duct configurations.
FAQ
- What is fire rated duct wrap used for?
It provides a protective barrier around ducts to slow fire spread, meet life safety codes, and protect surrounding areas in kitchens and industrial settings.
- Which rating is typically required for grease ducts?
Many installations seek up to a 2-hour fire resistance rating, depending on local codes and duct configuration.
- Is a 48-inch wide wrap better than a 24-inch wrap?
Wider wraps cover larger ducts, reducing seams and installation time, but require compatible duct dimensions and proper mounting.
- Should I choose a reflective foam core?
Double-sided reflective foam cores can improve thermal performance while providing moisture resistance in certain environments.
- Do these wraps work for both grease and air ducts?
Many options are certified for both grease and air ducts, but always verify the product’s listed certifications for your specific duct type.
- What installation cautions should I follow?
Follow manufacturer guidelines for surface prep, layering, and securing wraps to prevent gaps or loose sections that could compromise performance.
