What material are your headliners made of?

Our headliner material is 100% nylon knitted material, just like comes in your car or truck from the manufacturer. It has 3/16 inch foam laminated to it, so the construction would be cloth/foam; this is what makes headliner material. There are a few different thicknesses of headliner material in automobiles today; 1/4 and 1/8; we prefer the 3/16 inch foam, because this will work for just about every car made today.
