Standard Specification for Asphalt-Saturated and Coated Organic Felt Base Sheet Used in Roofing
Also Known As:
The ASTM D2626/D2626M-04 (R2020) standard specifies the requirements for asphalt-saturated and coated organic felt base sheets used in roofing applications. These sheets are commonly used as the first ply of a built-up roof or as a vapor retarder. The felt is primarily made from organic fibers and may have mineral surfacing on the top side, with or without perforations.
The standard sets out specific physical requirements for the felt base sheets. These include pliability, breaking strength, and water vapor permeance. The sheets should have a smooth and uniform surface and be reasonably free of lumps and foreign particles.
The use of these asphalt-saturated and coated organic felt base sheets provides a reliable and durable roofing solution. The standard ensures that the materials used in the manufacturing of these sheets meet the specified requirements, providing quality and performance assurance for roofing applications.
