Current Work


The current work has to expand and to incorporate input
from fabricators of wet and dry insulation as well as
installation contractors in order to define the general
requirements to be incorporated in the recommended
practice.
A Draft of the recommended practice has been
distributed to the subcommittee for comment and should
be available by 1st of March for submittal to SC17.
