My metal cladding crew is scheduled to begin work just after the long weekend. This is good news as we can then finish the entire garage and finalize the building exterior.  What won’t work is the combination of screw they supplied along with my costly fire detailing on the garage.  For whatever reason the City requested fire proof walls be built in the garage.  This led to the garage walls being layered with 1 1/4 inch of type x drywall inside and out.  I bought $200 worth of expensive drywall self tapping screws but the siding guys are going to have to get more creative. 

not a lot of grip here.
