Standard Specification for Faced or Unfaced Rigid Cellular Phenolic Thermal Insulation
ASTM C1126-24
Organization:
ASTM - ASTM International
Year: 2024
Abstract: This specification covers faced or unfaced rigid cellular phenolic thermal insulation. Insulations in the form of boards shall be faced or unfaced, while tubular forms shall be unfaced. This specification does not apply to field expanded cellular phenolic materials. Materials covered by this specification are used as roof insulation; sheathing or rigid board for non-load bearing, building material applications; and pipe insulation for use at specified temperature ranges. Type II Grade 1 and Type III Grade 1 materials with an appropriate vapor retarder covering on the warm surface can be used to a lower temperature limit. The thermal insulation shall be of the following types and grades: Type I, for use as roof insulation board and produced without integral vapor retarder facers; Type II, for use as sheathing or rigid panel for non-load bearing applications and produced with integral vapor retarder facers; Type III, for use as pipe insulation and produced without integral vapor retarder facers; Grade 1, closed cell material; and Grade 2, open cell material. Materials shall be sampled, prepared, tested, and conform accordingly to the following physical properties: density; compressive resistance; tensile strength; apparent thermal conductivity; dimension stability; water absorption; water vapor permeance and permeability; flame spread index; and smoke developed index.

| scope | 1.1 This specification covers faced or unfaced, rigid cellular phenolic thermal insulation. Boards shall be faced or unfaced. Tubular forms and board cut from a block or bun covered by this standard shall be unfaced. It does not apply to field expanded cellular phenolic materials. Note 1: If a facer or vapor retarder is to be used for the tubular form or board, then refer to Practice C921. 1.2 Materials covered by this specification are used as roof insulation; sheathing or rigid board for non-load bearing, building material applications; and pipe or board insulation cut from a block or bun for use between −40 and 257°F (−40 and 125°C). Type II and Type III materials with an appropriate vapor retarder covering on the warm surface are used to a lower temperature limit of −290°F (−180°C). (See 7.3.) 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This specification covers closed cell rigid cellular phenolic thermal insulation manufactured using blowing agents with an ozone depletion potential of 0 (ODP 0). 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 16. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. | |
