Sagging headliner is one common problem faced by owners of old cars. Over the years, the headliner loses its grip from the roof of the vehicle’s interior cabin and slowly drops down.
If a headliner sags in the front, middle, or rear, the driver’s vision may be impaired, which is a dangerous situation to drive in.
A sagging headliner defeats the purpose of a headliner, which is to act as a ceiling in the vehicle and improve the aesthetic look of the interior cabin.
In this article, we will examine all you need to know about headliners, why they sag, how to fix them, and how to prevent sagging headliners.
What Is A Headliner?
Many people do not know what a headliner means in the automobile industry.
For those who do not know, the headliner is just a material installed on the roof of the vehicle’s interior cabin. The headliner acts as a ceiling, which is glued onto the headliner board, which acts as a decorated structural frame for the headliner.
The purpose of a headliner is to improve the aesthetic look of a vehicle’s interior cabin and act as an insulator material from cold and hot weather conditions.
In addition, the headliner acts as a sound dampener, which aims to keep noise out of the vehicle’s interior cabin, improving the interior cabin’s serenity while driving.
It is important to know that headliners do not remain rigid forever as, over time, they begin to sag.
Why Causes Sagging Headliner?
No car owner wants a sagging headliner, but unfortunately, some people still experience it. But why do headliners start to sag?
Here are some of the reasons why headliners start sagging;
The Use of Low-Quality Foam
The foam quality used as an insulating material when manufacturing the headliner is also a major determining factor. Most headliners that sag are produced with low quality; therefore, the foam sandwiched between the headliner board and the headliner starts to pull apart, causing the headliner to sag over time.
As we all know, there is a greater probability of experiencing a sagging headliner in older vehicles than in newer vehicles. The age of a vehicle is a major factor that causes headliners to start sagging.
Defective Manufacturing Methods
Most vehicles that have sagging headliners were produced long ago when the manufacturing processes for installing headliners were not yet perfected; therefore, there is a lower probability of modern vehicles having sagging headliners because, over time, the manufacturing process of headliners has improved drastically.
Another cause of vehicle sagging headliners is manufacturers’ use of low-quality glue to install a headliner. Low-quality glue loses its integrity quickly, and the headliner will begin sagging over a few years.
Using low-quality materials will always produce poor results and the quality of the finished product, and one should not be surprised if these products fail suddenly.
Extremely Hot Temperatures
The integrity of materials used to produce headliners usually deteriorates quickly under extremely hot weather conditions. When exposed to extreme heat for a long time, the headliners begin to unglue from the headliner board and begin to sag. You will also notice that states that experience extremely hot weather conditions have more cases of sagging headliners.
