ASTM-C1149 › Standard Specification for Self-Supported Spray Applied Cellulosic Thermal Insulation
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers self-supported spray applied cellulosic thermal insulation for use as thermal insulation or acoustical absorbent material, or both. The chemically-treated cellulosic materials that are also covered in this specification are used for pneumatic applications operating within a specific temperature range. The materials are classified into two types based on the type of adhesive used and exposure of the application. Specimens for testing should be prepared and tested using the prescribed methods and should conform to the specified values of density, thermal resistance, surface bonding characteristics, adhesive strength, cohesive strength, smoldering combustion, fungi resistance, corrosion, moisture vapor absorption, odor, flame resistance permanency, substrate deflection, and air erosion.

1.1 The specification covers the physical properties of self-supported spray applied cellulosic fibers intended for use as thermal insulation or an acoustical absorbent material, or both.
1.2 This specification covers chemically treated cellulosic materials intended for pneumatic applications where temperatures do not exceed 82.2°C and where temperatures will routinely remain below 65.6°C.
1.2.1 Type I—Material applied with liquid adhesive and suitable for either exposed or enclosed applications.
1.2.2 Type II—Materials containing a dry adhesive that is activated by water during installation and intended only for enclosed or covered applications.
1.3 This is a material specification only and is not intended to deal with methods of application that are supplied by the manufacturer.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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.
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.
