What is a headliner?

Headliners are made of composite fabrics, a combination of different materials with different functionalities. The composite parts are adhered to the roof of the car and help to improve the interior appeal as well as provide an element of insulation against heat and noise.

A typical headliner consists of multiple layers: a face side, a rigid core in the center, and a backing. The different layers consist of a multitude of materials such as knit or non-woven fabric, rigid foam, reinforcement material, etc. Liquid and dry adhesives (film, web, net) are then used to bond the different layers together in order to enhance the headliner’s unique shape and contours.

What is the function of headliner ? 

The multi-layered headliners bring together various functionalities:

  • better look and comfort through soft touch
  • stiffness of the roof
  • absorption of excess noise from the outside
  • insulation against heat and cold, regulation of internal temperature
  • improved acoustics for audio systems
