ASTM C1902 is the ASTM standard specification for cellular glass insulation used in building and roof applications. It helps define the expectations for this insulation material so buyers, specifiers, and quality teams can evaluate products more consistently. By focusing on a clear technical specification, the standard supports more reliable material selection, procurement, and compliance review for projects that use cellular glass insulation in building envelopes and roof assemblies.

What is ASTM C1902?

ASTM C1902 is a product standard that addresses cellular glass insulation intended for building and roof applications. As a specification, it is used to help define the requirements a material should meet for these uses, supporting more consistent comparison between products from different manufacturers. In practical terms, ASTM C1902 serves as a technical reference for identifying cellular glass insulation suitable for project documentation, quality control, and specification writing. It is most relevant when a project calls for a standardized insulation product for building or roofing work.

Where is ASTM C1902 used?

ASTM C1902 is commonly used in construction and building-envelope work where cellular glass insulation is selected for roofs and related building applications. It may appear in project specifications, purchasing documents, submittals, and product evaluation processes for insulation used in assemblies that require a defined standard of performance. Contractors, designers, inspectors, and procurement teams can use ASTM C1902 as a reference when confirming that a cellular glass insulation product aligns with the intended application and specification requirements.

Why is ASTM C1902 important?

ASTM C1902 is important because it gives stakeholders a consistent technical basis for evaluating cellular glass insulation used in building and roof applications. That consistency can support compliance efforts, reduce ambiguity in product selection, and improve quality control during procurement and installation planning. For specifiers and purchasers, ASTM C1902 helps make product comparison more straightforward and can lower the risk of using materials that do not match the intended application. It is a useful reference for dependable specification and review.
