American Gypsum wallboard installed backwards /
To Whom It May Concern;
I understand on the project listed above that the contractor has installed American Gypsum's 1/2" FireBloc
Type C wallboard on the ceiling to ensure the specified fire rating (see below), with one piece of wallboard
installed backwards - or with the back of the panel facing towards the floor.
American Gyp§um's
1/2" FireBloc Type C wallboard
UL classified panels like our 1/2" FireBloc Type C wallboard have a front and a back - with the front of the
panel having tapers along the long edges to help with finishing using joint compound and tape. But the fire
resistance of these UL classified panels is the same from either direction, and the inadvertent application of
drywall with the back of the panel facing out - does not take away from the fire rating of a ceiling or wall
assembly.
Please let me know if you have any additional questions.
Regards,
