Work Item
ASTM WK91681
Revision of C991-23 Standard Specification for Flexible Fibrous Glass Insulation for Metal Buildings
Rationale
Section 6.2 covering faced insulation is being revised to better spell out the Specification C1136 requirement, including exception for non-vapor retarding applications. Section 4.1.1 and Note 1 are also revised as appropriate to that change. Also, a definition for “tab” is being added. Only the above-noted sections are being considered in voting on this ballot item. Thank you.
