Standard Specification for Asphalt-Coated Glass Fiber Base Sheet Used in Roofing
Also Known As:
The ASTM D4601/D4601M-04 (R2020) standard outlines the requirements for asphalt-impregnated and coated glass fiber base sheets used as the initial layer in built-up roofing systems. These sheets may also be employed as vapor retarders under roof insulation or between multiple layers of insulation.
According to the standard, the materials must meet the specified physical criteria, dimensions, and masses. The base sheet should be flexible and unroll smoothly without cracking or being excessively sticky. This ensures that the installation process is efficient and that the sheet maintains its integrity during application.
To ensure the quality of the product, the specification includes tests to evaluate properties such as breaking strength, moisture content, and pliability. By subjecting the specimens to these tests, manufacturers can verify that the base sheets meet the necessary performance requirements.
