ASTM C1423-14

Standard Guide for Selecting Jacketing Materials for Thermal Insulation

SIGNIFICANCE AND USE
4.1 This standard is intended to be used by engineers and designers as a guide to assist them in selecting appropriate thermal insulation jacketing materials. As a guide, it can be used to identify performance characteristics that might be necessary for a particular insulation jacketing system. This guide is not a specification and therefore should not be used as such. It might, however, be useful in writing a specification. Specification C921 can also be used to determine properties of jacketing materials for thermal insulation.
SCOPE
1.1 This guide covers criteria for selecting thermal insulation jacketing materials and is not intended for use as a performance or product specification.  
1.2 This guide applies to jacketing materials applied over thermal insulation for piping, ducts, and equipment.  
1.3 This guide includes jacketing materials used over thermal insulation whether the insulation is in the form of pipe, board, or blanket, or field applied materials that are self-supporting, including insulating cements.  
1.4 This guide does not include covers or other retaining walls that contain loose fill, other nonsupporting insulation materials, or conduits or containers for buried insulation systems.  
1.5 This guide does not include mastics and coatings and their reinforcements.  
1.6 The values stated in inch-pound units are to be regarded as the standard. The SI values given in parentheses are provided for information only.  
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

4. Significance and Use
4.1 This standard is intended to be used by engineers and designers as a guide to assist them in selecting appropriate thermal
insulation jacketing materials. As a guide, it can be used to identify performance characteristics that might be necessary for a
particular insulation jacketing system. This guide is not a specification and therefore should not be used as such. It might, however,
be useful in writing a specification. Specification C921 can also be used to determine properties of jacketing materials for thermal
insulation.
5. Materials and Manufacture
5.1 Jacketing materials may be composed of a single material or a lamination of several components. The material may be in
the form of rolls or sheets or preformed to fit the surface to which they are to be applied. The materials may be applied in the field
or may be a factory-applied composite with the insulation.
5.2 Metallic:
Available from Technical Association of the Pulp and Paper Industry (TAPPI), 15 Technology Parkway South, Norcross, GA 30092, http://www.tappi.org.
C1423 − 14
5.2.1 Metallic jacketing materials are those whose primary material (usually the component of greatest thickness) is metal, such
as, aluminum, coated steel, and stainless steel. The metal may be smooth, corrugated, or embossed. The dimensions of corrugations
(pitch and depth) may be specified by the purchaser for interchangeability, constant rigidity, and control of sizes. The inner surface
of metallic jacketing materials may be coated or covered with a moisture resistant film to retard possible galvanic and/or chemical
corrosion of the jacketing.
5.2.1.1 Aluminum jacketing materials can should be manufactured from in compliance with Specification B209C1729, Type
3003, 3004, 3105, 5005, 5010, 5020, or 1100 aluminum, temper ranges which incorporates by reference the chemical composition
and physical properties of Specification B209from H14 (half hard) through H19 (full hard). Where ambient conditions are severe,
. Where ambient conditions are particularly corrosive or when a higher surface emissivity is desired, the outer surface of the
aluminum may be coated when specified. Thicknesses generally available are from 0.006 to 0.040 in. (0.15 to 1.02 mm).with paint
or plastic film.
5.2.1.2 Steel Coated steel jacketing materials can be manufactured from Specification in compliance with several Specifications
including A366/A366M, Type and A1008/A1008M using alloys 1010, 1015, or 1020 steel. The outer surface is typically protected
by aluminizing, galvanizing, or coating with plastic film or enamel to retard exterior corrosion, or a combination thereof. another
type of corrosion resistant metal alloy. Metal thicknesses generally available are from 0.010 to 0.019 in. (0.25 to 0.46 mm).
5.2.1.3 Stainless steel jacketing materials can should be manufactured from in compliance with Specification A240/
A240MC1767, Type 301, 302, 303, 304, or 316 stainless steel, hardness B85 (soft which incorporates by reference the chemical
composition and physical properties of Specification A240/A240Mannealed). Thicknesses generally available are from 0.010 to
0.019 in. (0.25 to 0.46 mm).
5.3 Nonmetallic and Laminated Jacketing:
5.3.1 Laminated jacketing materials are typically manufactured from combinations of plastic films, plastic composites, metallic
foils, reinforcing fabrics, papers, or felts selected to obtain the required performance characteristics. For flexible low permeance
vapor retarders, see Laminated jacketing for outdoor applications should be manufactured in compliance with Specification
C1136C1775.
5.3.1.1 One common type of laminated jacketing is flexible low permeance vapor retarders, which should be manufactured in
compliance with Specification C1136.
5.3.2 Textile or cloth jacketing materials are woven or knitted of textile yarns. Commonly available forms are 4, 6, or 8 oz/yd
(0.14, 0.20, or 0.27 kg/m ) cotton canvas, various weaves of glass fiber yarns, presized glass cloth, knit, or woven plastic fibers.
5.3.3 Plastic jacketing materials are manufactured in various forms and types. Thicknesses generally available are from 0.003
to 0.035 in. (0.08 to 0.89 mm). Various materials can be used such as poly-vital chloride (PVC), CPVS, fiberglass reinforced plastic
(FRP), and others.
5.3.4 Saturated felt or cloth jacketing materials are manufactured from various base felts or cloths that have been impregnated
with bitumen or resinous materials. Examples: Glass fiber, polyester fiber, polyolefin fiber. This definition does not include tar
paper, asphalt paper, or other paperboard materials or other products, such as rag felt, that are made out of waste and they do not
represent a continuous and resistant base for a jacketing.
5.3.5 Rubber containing membranes are manufactured from combinations of layers of various rubber containing materials such
as butyl rubber or rubberized bitumen with layers of other materials such as plastic films, metallic foils, reinforcing fabrics, or a
combination thereof.
5.4 Classifications used in jacketing specifications—Each of the various ASTM specifications for jacketing contains a different
classification system appropriate for that material. While each individual ASTM specification should be consulted for the details,
the general outlines for each of these systems are shown below.
5.4.1 Specification C1136 Flexible Low Permeance Vapor Retarders

6. Physical and Chemical Performance Considerations
6.1 This section includes a number of performance issues that should be considered when using this guide to select a jacketing
material for thermal insulation. Some may not be applicable to the particular application. However, to be certain none are
overlooked, the user should consider all materials initially and then eliminate those that are not applicable.
6.2 Abuse Resistance—Consideration should be given to the ability of a jacketing material to withstand a variety of physical
conditions in excess of required functional design criteria. Prior to selection, consideration should be given to the expected
intensity and types of abuse as well as the length of time the jacketing material is expected to withstand a given level of
