Our Aluminium Under-Bonnet Liner is designed to reduce noise over a broad frequency range whilst reflecting engine heat away from the bonnet or cabin.  This will help to protect your paintwork and improve cabin comfort as well as reducing overall noise due to its open-cell structure.

This liner can be applied to the underside of the bonnet or engine cover by itself. However, it can also be applied over a layer of Fatmat Sound Deadener as these two types of mat are designed to complement each other to give a greater reduction in noise.  It has excellent resistance to heat, moisture and non-aromatic petro-chemicals.
