What is the importance of the car roof liner and its purpose, you ask?
Protects you from extreme temperatures for maximal comfort
The roof liner is responsible for keeping the temperature inside the vehicle from heating and getting cold excessively. Especially on a hot summer day where you are trying to keep as cool as possible, having a stable roof liner can really help stretch out the duration of your Air Conditioner so that it stays cooler for longer. Likewise during Winter, where keeping warm is key, besides, everyone knows how painfully annoying it is to drive with cold fingers.
Negates Noise Outside
The car roof liner helps reduce or block the noise that is coming from the outside into the vehicle. If you are a young parent with a little one, perhaps having extra noise protection could be very useful in keeping your child fast asleep. Nonetheless, any sound is better than the noise of honking and beeping trucks. No need to scream over your Bluetooth connected calls, reduce that traffic noise to a minimum.
