3M Fire Barrier Duct Wrap 615+ 24″ x 25′ Roll
This duct wrap provides a lightweight, space-saving solution for grease ducts and ventilation ducts. It is designed as an alternative to traditional shaft enclosures and supports multi-layer use where installation space is tight. Best for contractors needing a compact wrap that still delivers fire resistance. Caution: ensure proper layering for multi-duct configurations to meet local codes.
3M Fire Barrier Duct Wrap 615+ 48″ x 25′ Roll
Best for larger grease ducts and commercial kitchens requiring certified life-safety compliance. This wrap is UL and Intertek certified and protects both grease and air ducts, meeting ASTM E2336 and ISO 6944 test standards. Choose this if you need strong code compliance and a robust fire barrier for larger installations. Caution: heavier and longer rolls may require more handling space during installation.
3M Fire Barrier Duct Wrap 615+ (48″ x 25″)
Ideal for commercial kitchens using double-layer grease duct systems. This model emphasizes a butted inner layer in multi-layer arrangements to optimize fire resistance while maintaining duct accessibility. Best for projects where a precise two-layer approach is planned. Caution: verify duct geometry to ensure full wrap coverage.
HOODMART 3M Fire Barrier Duct Wrap 615+ 24″ x 25′ Roll
Provides up to a 2-hour fire-resistance rating and is positioned as an alternate to shaft enclosures for grease ducts. Best for facility upgrades where space-saving wraps are preferred and two-layer installation is feasible. Caution: ensure compatibility with existing grease duct configurations before purchase.
Sasylvia Fire Rated Duct Wrap 24″ x 17′
Withstand extreme heat up to 1000°C and fully encase ducts for thorough protection. Best for high-heat grease ducts where complete coverage is required. It supports full 360-degree duct encasement to minimize exposed gaps. Limitation: higher heat rating may indicate a more specialized use case; confirm duct dimensions and fit before ordering.
US Energy Products R-8 Duct Wrap 2 ft x 25 ft
Double-sided reflective, class 1/A fire-rated wrap with a fiberglass core. Best for projects needing a reflective barrier that also delivers fire resistance. Choose this if you want a light-tight, waterproof option with simple installation across various duct shapes. Caution: confirm compatibility with duct insulation thickness and expected service temperatures.
US Energy Products R-8 Duct Wrap 4 ft x 50 ft
A larger roll option for extensive duct networks, offering double-sided insulation and class 1/A fire rating. Best for projects with longer duct runs or multi-duct installations. Caution: heavier rolls may require equipment or additional manpower for handling during installation.
Buying Guide
- What fire rating do I need? For most grease ducts in compliant kitchens, up to 2 hours is standard; verify applicable local codes and standards (IBC, NFPA, IMC).
- Which wrap is best for two-layer grease ducts? Look for products specifically noting two-layer or butted inner layer design to minimize air gaps.
- Is space a major constraint? Choose lighter, thinner wraps for tight spaces, or larger width rolls for quicker installation on bigger ducts.
- Are certifications important? Opt for wraps with UL or Intertek listings and recognized test standards (e.g., ASTM E2336, ISO 6944) when code compliance matters.
- What about durability and environmental exposure? Consider wraps with waterproofing or scrim-reinforced foil facings if ducts encounter moisture or frequent cleaning.
FAQ
- What is the typical purpose of 2-hour fire-rated duct wrap?
It provides a fire barrier for grease ducts and ventilation systems, reducing flame spread and heat transfer during a fire. - Can I use any wrap on a grease duct?
Not all wraps are designed for grease ducts; select products specified for grease ducts and validated by safety codes. - Do wraps require a specific installation method?
Many wraps require one or two layers, with attention to overlaps and butted joints; follow product instructions and local codes. - Are there heat resistance limits I should know?
Some wraps are rated for extremely high temperatures; choose a product whose rating matches your duct’s operating and emergency conditions. - How do I decide between 24″ and 48″ widths?
Wider wraps cover more surface area per piece and reduce joints, but require appropriate handling space and duct geometry assessment.
