(Specification)Standard Specification for Fiberglass Reinforced Styrene-Butadiene-Styrene (SBS) Modified Bituminous Sheets with a Factory Applied Metal Surface
Standard Specification for Fiberglass Reinforced Styrene-Butadiene-Styrene (SBS) Modified Bituminous Sheets with a Factory Applied Metal Surface
ABSTRACT
This specification covers fiberglass reinforced bituminous sheet materials modified by styrene-butadiene-styrene (SBS) thermoplastic elastomer, and are surfaced with a factory applied continuous metal foil. These materials are intended for use in the fabrication of multiple ply roofing and waterproofing membranes and flashings. This is intended as a material specification only, and does not address specific roof constructions or application techniques. The specified tests and property limits are intended to establish minimum properties. Roof system design criteria such as fire resistance, field strength, impact/puncture resistance, material compatibility, uplift resistance, and others are factors beyond the scope of this specification. The properties for which the materials shall be tested on and consequently conform to are thickness, net mass per unit, back surface coating thickness, peak load value, elongation at peak load, ultimate elongation, tensile-tear strength, low-temperature flexibility, dimensional stability, compound stability, cyclic thermal shock, water absorption, and moisture content.
SCOPE
1.1 This specification covers fiberglass reinforced modified bituminous sheet materials that use styrene-butadiene-styrene (SBS) thermoplastic elastomer as the primary modifier and are surfaced with a factory applied continuous metal foil. These materials are intended for use in the fabrication of multiple ply roofing and waterproofing membranes and flashings.
1.2 This specification is intended as a material specification only. Questions regarding the suitability of the specific roof constructions or application techniques are beyond the scope of this specification.
1.3 The specified tests and property limits are intended to establish minimum properties. In place roof system design criteria such as fire resistance, field strength, impact/puncture resistance, material compatibility, uplift resistance, and others, are factors beyond the scope of this specification.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.5 The following precautionary statement pertains to the test method portion only, Section 8 of this Specification: 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.

Overview
ASTM D6298/D6298M-16(2023) is the international standard specification set by ASTM International for fiberglass reinforced bituminous sheet materials modified with styrene-butadiene-styrene (SBS) thermoplastic elastomer. These sheets are characterized by a factory applied continuous metal foil surface and are predominantly used in the fabrication of multi-ply roofing and waterproofing membranes and flashings. This standard focuses solely on defining the minimum physical properties and requirements for the material itself, not on specific roof system designs or application methods.
Key Topics
Material Composition
- Fiberglass reinforcement for added strength and durability
- SBS-modified bituminous coating for enhanced elasticity and weather resistance
- Factory applied metal foil surface for improved reflectivity and protection
Physical Properties and Test Methods
- Required conformity to minimum specifications for properties such as thickness, coating thickness, net mass per unit area, and metal foil quality
- Properties tested include peak load, elongation, tensile tear strength, low-temperature flexibility, dimensional stability, compound stability, cyclical thermal shock, water absorption, and moisture content
- Use of referenced ASTM test methods such as D5147/D5147M and D7051 for property validation
Workmanship and Quality Assurance
- Finished product must be free from defects such as holes, cracks, tears, or delaminations
- Criteria for uniformity of the metal surface and proper selvage width
- Inspection protocols as per the standard, including rejection and resubmittal processes
Packaging and Marking
- Rolls must be securely wrapped for protection and easy handling
- Product branding and mandatory marking with essential compliance information
Applications
The ASTM D6298/D6298M-16(2023) standard is vital for professionals engaged in:
Multi-ply Roofing Systems
- Used as durable waterproofing sheets in layered roofing assemblies, leveraging the SBS-modified bitumen for flexibility and the metal foil for additional weatherproofing and reflectivity
Waterproofing Membranes and Flashings
- Essential for the construction of reliable and long-lasting barriers against moisture infiltration, including building foundations, decks, and other critical areas
Industrial and Commercial Building Projects
- Suitable for environments requiring high performance against thermal cycling, moisture, and mechanical stresses
Material Procurement and Specification
- Provides architects, engineers, and contractors with a reliable base specification for selecting fiberglass reinforced, SBS modified bituminous sheet materials with metal foil surfaces
This standard specification ensures material quality which enables durable, high-performance building envelope systems that require both flexibility and protection from weather elements.
Related Standards
For full compliance and enhanced roofing and waterproofing system design, reference to related ASTM standards and documents is recommended:
- ASTM D1079 - Terminology Relating to Roofing and Waterproofing
- ASTM D5147/D5147M - Test Methods for Sampling and Testing Modified Bituminous Sheet Material
- ASTM D7051 - Test Method for Cyclic Thermal Shock of SBS-Modified Bituminous Roofing Sheets with Factory-Applied Metal Surface
Examining these related standards can help ensure appropriate terminology, thorough performance testing, and complete material validation throughout the lifecycle of the roofing or waterproofing project.
