What’s the difference between 197 and 394? Mil. I see the 394 is higher

The Siless sound deadener thermal shield max is a good 16th of an inch thicker and not as pliable

How much does it weigh???

Using a digital bathroom scale 1 pound per 11 3/4” X 15 3/8” sheet each

Is this fire proof as I dont have alot of clearance between engine and cover ?

As I understand, it's not fire proof but it's fire resistant .
