What is the purpose of Jute like padding behind fender on firewall

[ramchol76]

I notice a fibrous padding behind the fender and body like in picture. Is there a specific name to it? what is its function?

I believe it is a sound deadening pad, my Denali has it and has the sound deadening rpo code

That was my first guess as well. Sound deadening and I cannot think of any other reasoning.

Yup, sound deadening

Agreed, sound deadening.

I'd think that would just cause more rust issues. Jute just sucks up moisture, and holds it.

Mine is like the type of carpet pad that's under the trunk carpet in most cars. Don't know what that's called?

I love the smell of jute and gas in the morning. It’s a (air cooled) VW thing.

I sure wish my 2019 SLT Yukon had MORE sound deadening material. It is the loudest and roughest riding GM product I’ve ever owned!!
