Aerocel® EPDM Sheet

Aerocel-Sheet

Closed Cell Elastomeric Thermal lnsulation for HVACDuct Lining and Wrapping

Aerocel® EPDM Elastomeric Sheet Insulation is a flexible closed cell and lightweight elastomeric material with a smooth and durable surface, designed for insulating air ducts internally and externally, air handling cabinets, air terminal devices, and more. With low moisture absorption and low water vapor transmission, Aerocel can be used both as an internal and external insulation for all kinds of ducting systems and air distribution system components, warm and cold. Ducts can be located indoors or outdoors, and Aerocel will be unaffected. Aerocel is available in 3’ x 4’ flat sheets and rolls suitable for automated duct liner application equipment, in thicknesses of 1/8”, 1/4”, 3/8”, 1/2”, 5/8”, 3/4”, 1”, 1-1/4”, 1-1⁄2” and 2”.

Aerocel® sheet meets the standards of UL 181 for mold growth/humidity, air erosion and passes ASTM G 21, Fungal Resistance.

Aerocel® EPDM elastomeric sheet and roll insulation is fully tested for and meets or exceeds the performance criteria of ASTM C 1534, Type I, Standard Specification for Flexible Polymeric Foam Sheet Insulation Used as a Thermal and Sound Absorbing Liner for Duct Systems.

Aerocel EPDM is manufactured to consistently provide tested values – not theoretical calculations – on these key performance criteria for mechanical system insulation:

Thermal Conductivity: 0.245
Water Vapor transmission: 0.03
Fire Rating: Will not contribute significantly to fire (simulated end-use testing).

Aerocel Pipe lnsulation in 3/8″, 1/2″, 3/4″,  1″, 1-1/4″, 1-1/2″ and 2″  thicknesses has a flame spread rating of 25 or less and a smoke developed rating of 50 or less as tested by ASTM E 84 “Surface Burning Characteristics of Building Materials.”

Note: Numerical flammability ratings alone may not define the performance under actual fire conditions. They are provided only for use in the selection of products to meet limits specified.

Key Benefits

  • Quiet Operation
  • Energy Saving
  • No Moisture Generated Concerns in Duct
  • Eases Compliance for IAQ Needs
  • Resists Microbiological Growth
  • Durable, Cleanable
  • Accurate Air Delivery

Uses

Besides being the ideal insulation for many kinds of piping systems and equipment, Aerocel® is also used as insulation for all kinds of HVAC ducting systems, including supply, return and intake air. Aerocel® EPDM
Elastomeric Sheet is an excellent choice for insulating duct work, both internally lined and externally wrapped.Aerocel® sheet makes an ideal choice for HVAC duct systems because it is a low density, light weight productthat also serves as an efficient acoustical absorber and an excellent thermal insulator reducing noise generated by equipment, cross-talk, air movement and the expansionand contraction noises of sheet metal ducts. Because of the highly efficient thermal insulation that Aerocel provides.Aerocel makes an excellent energy saving component of air distribution systems. Aerocel® has been favored over fibrous insulating materials mainly because of the possible dangers and health concerns with the use of fibrous materials.

Resistance to Moisture Vapor and Liquid Flow

The closed-cell structure of Aerocel EPDM lnsulation effectively retards the flow of moisture vapor, and Aerocel EPDM is considered a low transmittance vapor retarder. Aerocel EPDM requires no supplemental vapor retarder protection.  EPDM is a water barrier material and will not allow liquid water to pass or wick.

Application

Aerocel® EPDM elastomeric sheet is flexible and easy to use for a wide variety of jobs including large air ducts and inside air handling panels. When used in duct lining applications, SMACNA duct lining practices are to be used for gluing and pinning Aerocel® to the sheet metal. An ASTM C 916 compliant duct liner adhesive** is to be used. Different adhesives will yield different performance characteristics when holding Aerocel® to sheet metal. Duct liner pins that mechanically attach, weld, or adhere to the sheet metal, and have a shank length that is equal the thickness of the insulation must be used. After installation, and prior to occupancy, blow out duct system to remove any cutting scraps or foreign material remaining in the duct.

In addition to the specifications listed below, Aerocel EPDM also conforms to the following: ASTM C 534, ASTM D 1056, NY City MEA #171-04-M, City of LA RR-8413, UL 181 Section 12 Mold GrowthIHumidity, UL 181 Section 17 Air Erosion, UL 94 5 V-0, UL 723, NFPA 90A & 90B, MIL l528OJ.
