Better than EVER

I really like the upgrades over the previous design. The rubber may be a little thinner but the foam definitely makes up for it. I love how easy it is to manipulate into the small spots on the installation to make it so much easier. I love the direction NVX took adding the foam to the design.
Keep it up guys.

Nice improvement

Using this product in the door areas for mid bass improvement. I used 2 of the SDBBP40 (without the third layer of foam) to cover the whole inside of the vehicle. When I ran out of material and needed a bit more for the doors, I was thrilled to Find NVX added a dampening material with the foam backing. This is a NVX install all the way: speakers, amps, cables...

Great value, excellent product

I'm not sure how there could be a complaint here. I was pleased with the quantity of material I received given the price I paid. It's extremely adhesive material and very easy to roll down. It's malleable, yet heavy. It worked very well for the trunk and rear doors, and I may need a smaller quantity to cover the front doors, but that's still a full car under $100. 5 stars.

Excellent

It work so good my trunk stop from shaking, and it was a great price

Works amazingly well, Super easy Install.

This multi layer sound deadening is great. In the past I have used multiple layers to get the best results for my vans and this stuff combines them to cut install time in half. Noise inside my camper van is significantly cut making long drives much more pleasant. The sheet size is perfect to cover large areas. My only complaint is that some of the foam layer tore while rolling making it hard to get super clean look. But since most areas get hidden this is not a problem

Best bang for your buck

I would recommend this product because I feel it compares very greatly to other high end brands of their competition. The only negative thing I have to say about it is that the top foam layer can rip very easily if your not very careful and try to rush the install. There’s no smell compared to brands of the same price of similar items .

Good product

Decided to try this over the regular sound dampener due to the foam layer. So far it seems to be working and has minimized the rattling from my bass speaker in the trunk.

Well worth the upgrade over thin 2-layer CLD

This was installed 2 years ago, I just bought more NVX 3-layer to get more coverage on the floor and doors. It definitely does the job and is easy to apply. The foam material helps in my application for thermal insulation and seems to work better overall than the cheap 2-layer stuff I have in the rear of the vehicle. It also packs down less under foot areas which are just covered by thin aftermarket carpet.

Great value

The NVX 3 layer sound deadening material is a great value. Soundskins costs more than double for only 2 layers of material for the same amount of sqft.

NVX 20 sqft.- $70 3 layer
Soundskins 20 sqft. - $174 2 layer

Don't waist your money on soundskins or other brands. They are way over priced.

Best deal in sound deadner

If you are looking for sound deadner this is it. Very thick like some of the higher end deadner at a fraction of the cost. Win/win in my book.

Awesome 195 mil deadener!

It’s not listed in the description but it’s written on the box it’s 195 mil. So it’s thick and heavy stuff. For the price I don’t think it can be beaten. I like that it’s a 1 application product with the foam already on it. I deadened my doors in the cold because I am installing 4 8’s into each of my front doors. I wanted to give them the best environment possible to produce good midbass. I lightly heated the panel with a heat gun, and it stuck perfect. The door is extremely solid with a satisfying thud when you tap it! I have enough to do my whole Expedition and I can’t wait for it to warm up so I can get it then!
