The importance of insulation liner under the bonnet and trunk lid to the car are as follows:

• Reduce the heat radiate from the cabin to the hood, as too much heat radiation is a catalyst for color deterioration on the bonnet. 

• The car’s color will be is pale, matte  and grain earlier. If such insulation liner is installed, it will maintain the color on the car’s bonnet to be radiance and shiny as close as color on the surroundings parts of the car such as left and right front fenders.

• Reduce noise from the engine room. Filter and absorb the noise to be softer.

• Reduce echo noise while the panel (Bonnet and Trunk lid) is closed or impacted by any objects.

• In case of the insulation liner under trunk lid, it will reduce the outside heat radiate into the storage cabin.

• Untidiness of piping, wiring, or rods under the bonnet and trunk lid could be hidden.
