A new Task Group on Molded Silicone Seals has formed in ASTM Subcommittee C24.32 on Chemically Curing Sealants. The group will develop voluntary consensus standards for molded silicone seals on exterior joints in building envelopes, such as metal-to-metal joints in curtain walls.

Architects, engineers, and waterproofing consultants are invited to discuss proposed areas for standardization during the meetings of main Committee C24 on Building Seals and Sealants, June 24-27 in Norfolk, Va.

“As these products become more popular, it is necessary to develop consensus standards for their manufacture and proper use,” said the chairman of Committee C24, David H. Nicastro, P.E., CEO of Engineering Diagnostics, Inc., Austin, Texas.
