Active Standard: C1280 - 13a
Development of provisions outlining procedures for preventing moisture damage to gypsum sheathing. This project grew out of withdrawn negatives on a ballot to add a minimum ground clearance requirement to the Standard. It will either be a revision to Specification C1280 or end up as a separate Standard Practice or Guide, depending on where the work leads the task group.
