How can I get the sticker/decal my order didn’t have one?

I've used several boxes of this product. No decal present in any box I've used..

Will this work on the inside walls of a cargo van? reduce noise/vibration? insulate? reduce heat? repel water?

Thank you for your question. Siless Black 50 mil will reduce noice/vibration. Together with Siless 157 mil closed cell, installed as a second layer, will insulate/reduce heat, and will provide with weatherproof properties.

Can it be used uder the hood and will it hold up the the heat of the engine?

Thank you for your question. Siless Black 50 mil Sound Deadener Mat has a working temperature range from- 50 degrees to 210 degrees F. Also, for short period of time it would withheld heating of up to 375 degrees F. We won't recommend installing under hood in the engine compartment due to temperature constrains.

Good Product Reasonably Priced

I used this in conjunction with 200 mil foil covered self-stick foam to reduce noise and vibration inside the cab of my Polaris Ranger 1000. This product was the first layer and did a great job of reducing vibration and a fair job on noise. There was little to no noticeable smell and the thickness seemed spot on for my application. It was easy to work with (cut and shape) and stays put once it's rolled into place. I haven't evaluated heat retention or durability at this point. Overall, I'm very pleased with this product.

Quality product

Works very well. I used to insulate the outside of a sound booth from noise for remote work. Cut down on the bass noise by about -15 db coupled with acoustic foam. It does have a significant odor, so it helps to install in a well air circulated area. Easy to cut and to mold to a surface. Highly recommend.
