1. Understanding the Car Headliner
What is a headliner in a car, and why is it important?
A headliner is the fabric lining attached to the interior roof of your car. According to a study by the University of Michigan’s Transportation Research Institute in 2022, headliners provide thermal insulation, absorb sound, and enhance the overall aesthetics of the vehicle’s interior. It consists of several layers, typically including a foam backing (often polyurethane) attached to a headliner board. This design helps regulate temperature and reduce noise levels inside the car.
