UNIFRAX FYREWRAP ELITE 1.5 GREASE DUCT INSULATION ASTM E-2336

DOUBLE LAYER APPLICATIONS

Unifrax’s FyreWrap Elite 1.5 Duct Insulation is a two-layer flexible enclosure for one- and two-hour rated commercial kitchen grease ducts and hazardous exhaust ducts including chemical fume ducts.

FyreWrap Elite 1.5 Duct Insulation is tested per ASTM E-2336 and is acceptable as an alternate to a traditional fire-rated shaft. Installed as a two-layer system, FyreWrap Elite 1.5 complies with AC101 and the 2006 Edition of the International Mechanical Code (IMC).

Product Composition:

Core Material: FyreWrap Elite 1.5 incorporates Insulfrax Thermal Insulation as its core material. Insulfrax is a high-temperature insulation made from a calcia, magnesia, silica chemistry designed to enhance biosolubility. It provides excellent insulation in a noncombustible blanket product form. 

Encapsulating Material: The core insulation blanket is completely encapsulated in an aluminum foil fiberglass reinforced scrim covering. This scrim provides additional handling strength as well as protection from moisture absorption and tearing.

Features of FyreWrap 1.5 Grease Duct Insulation - Double Layer:

  • Complies with 2006 IMC and UMC
  • Tested per ASTM E-2336
  • Two-layer system; first and second layers utilizes butt joint only (no overlaps)
  • High-temperature, biosoluble insulation
  • Zero clearance to combustibles, at any location
  • 2-hour fire endurance rating
  • Alternate to shaft enclosure
  • GREENGUARD listed for Microbial Resistance

FyreWrap products offer solutions in applications such as:

  • Grease, HVAC Ducts
  • Railroad Tank Cars
  • Cable Trays, Conduit
  • Transit Cars
  • Control System Covers
  • Ships
  • Above Ground Storage Tanks
  • Expansion Joints
  • Marine Bulkheads, Decks
  • Fire Door Seals
  • Structural Steel
  • Chimney Liners
  • Construction Joints
  • Ceiling Air Diffusers
  • Curtain Walls/Safing
  • Hazardous Material Containers

BASIC INSTALLATION:
The FyreWrap Elite 1.5 Duct Insulation ASTM E-2336 System consists of a two-layer system applied directly to the duct surface. The FyreWrap Elite 1.5 insulation system may be installed at zero clearance to combustibles at any point. Install both layers of wrap with transverse (perimeter) and longitudinal butted joints. Between the first and second layers of wrap stagger transverse joints and offset longitudinal joints to different corners. All visually exposed blanket edges are to be sealed with minimum 3" wide aluminum foil tape and the use of filament tape is not required but is permitted to ease installation.

UNIFRAX FYREWRAP 0.5 PLENUM WRAP INSULATION

Unifrax FyreWrap 0.5 Plenum Insulation is a high temperature insulation blanket specifically designed to provide a single layer, flexible enclosure around combustible items located within fire-rated return air plenums.

New construction, building renovations or modifications to the electrical and mechanical systems may result in the installation of plastic pipe or plastic-coated cables that cannot meet the minimum combustibility requirements defined in the Mechanical Code.

FyreWrap 0.5 Plenum Insulation provides fire protection for these installed items by preventing flame propagation and smoke development in the plenum area.

FyreWrap Plenum Insulation incorporates Insulfrax Thermal Insulation as its core material. Insulfrax is a high temperature insulation made from a calcia, magnesia, silica chemistry designed to enhance biosolubility.  It provides excellent insulation in a noncombustible blanket product form. 

The core insulation blanket is completely encapsulated in an aluminum foil fiberglass reinforced scrim covering. This scrim provides additional handling strength as well as protection from moisture absorption and tearing.

APPLICATIONS:

Provides Passive Fire Protection for Combustible Materials Inside Air Plenums (Including above drop-ceiling return air)  The following items are common combustibles that may be installed inside plenums:

  • PVC Piping (Drain Lines / Bathroom Exhaust
  • Internet/Ethernet with plastic coated wiring
  • Electrical Wiring (Romex)
  • Plastic Electrical Conduit

INSTALLATION METHOD:

  • FyreWrap 0.5 Plenum Insulation consists of a single layer system applied directly on to the surface of the combustible item.

  • Cut the insulation to a length sufficient to wrap around the combustible item(s) plus provide a minimum 1" perimeter overlap.

  • Seal all cut edges with aluminum foil tape to ensure there is no exposed fiber.

  • Cut the adjacent piece of Plenum Insulation long enough to wrap around the circumference of the item plus a 1" perimeter overlap.  This piece shall also be installed with a minimum 1" longitudinal overlap on to the previously installed piece.

  • Stainless steel tie wire or ½” stainless steel banding should be utilized as a permanent attachment. Locate the wire or banding ½” from the blanket edge and on 11½” centers.

  • Twist tension the wire or tighten banding to firmly hold the wrap system in place, but not so tight as to cut or damage the blanket.  Hand tightening of wire is adequate.
