Dynaliner

Dynaliner is the most effective automotive thermal insulator. It is a soft, self-adhesive closed cell rubber that is resistant to both oil and water.

It is the closed cell form that is so crucial to its effectiveness at absorbing heat.

Acts as an under carpet padding material and its closed cell nature again adds benefit by making it extremely durable. Unlike traditional under carpet materials, it will not hold moisture (which is the number one reason the floor pans rust out on Alfa Romeos).
