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.
