The fabric or cardboard-like lining that covers the inner roof panel and roof bows is referred to as the headliner. This component plays a crucial role in the aesthetics and functionality of the vehicle's interior. The headliner not only enhances the visual appeal by providing a finished look to the car's interior but also contributes to noise dampening and insulation.

In addition, the headliner can provide some protection from moisture and temperature variations, as it often has an insulating layer that helps to regulate the interior environment. Its installation is typically secured to the roof structure of the vehicle, making it a vital part of the overall vehicle design and comfort.

Recognizing the headliner is important for appraisers as they assess damages related to interior components during physical damage evaluations. Understanding the function and placement of the headliner helps appraisers gauge repair costs accurately and provide a comprehensive assessment of the vehicle's condition.
