Subflooringis sometimes used over the sheathing. Sub-

flooring may be a pressed particleboard (where the finished

floor is carpet), or it may be plywood or waferboard (where

the finished floor is resilient tile, ceramic tile, slate, etc.). A

careful review of the specifications and drawings will show

whether subflooring is required, as well as the type and

thickness and location where it is required. It is taken off in

sheets the same as sheathing.
