Under hood Insulation Blanket

Greetings all, I am curious as to the function of the insulation blanket on the underside of the hood. Cowl induction I get but why the blanket? I've always ran with the impression that heat is the engines enemy so why keep it under the hood?
Thanks,
Hank

Sound deadening.

I guess I hadn't considered that. Interesting.
Thank you!!

It is Tied to the RPO Z87, the Custom Interior (a.k.a. Deluxe Interior).

All SS & ducted hood cars had hood insulation no matter what interior....Joe

In this instance the car is a standard interior. Was the decision to install blankets driven by solid lifter noise?
Thanks,
Hank

I wouldn't think so. My L48 RS/SS w/deluxe interior has the hood insulation.
