Abstract
The roof structure of a work vehicle cab is provided with a roof panel having a top surface exposed to the outside and a bottom surface facing the interior of the cab. A sound insulating foam liner is located under the roof panel and secured thereto by adhesives. The bottom surface of the foam liner is provided with ventilating channels. The ventilating channels have two sidewalls and a top wall extending between the sidewalls. A headliner is located below the foam liner and encloses the ventilating channels formed in the foam liner thereby forming ventilating ducts. A headliner mounting structure is also disclosed in which upstanding flanges around the perimeter of the headliner have slots that receive inward extending tabs on the frame to support the headliner.
