Soundsulate™ Next Generation, 1 lb. Mass Loaded Vinyl (MLV) Soundproofing Barrier Roll, 4' x 10' (40 sf)

First off, I used this in an attempt to quiet down the cackling rumble that is a 7.3 powerstroke diesel. I removed my dash and put down a solid layer of butyl rubber sound deadener then started laying down the Soundsulate MLV, this is no easy task as MLV is heavy and doesn’t contort very well on something like a firewall. What worked for me was starting from the top and working my way down then using preexisting screws and bolts from the firewall and hvac assembly to hold it in place. Ford used a molded sound barrier from the factory that I believe was polyethylene foam backed with maybe a 1/16” of MLV which I ended up removing. Anything I had left over from the dash I used on the floor pan. Though it isn’t silent in the cab the difference before and after is noticeable and impressive and definitely worth the trouble of removing the dash.

This product was very heavy and hard to use so sent it back. The description did Not explain it was so heavy and could not use it. Sent it back and only received 1/3nof the original price? I wasn all my money back. Amazon should Not use this seller

This product is great, came packaged nicely no damage to product. A little tuff to work with but if you need that 3rd layer great stuff and not a bad price

Product reduced noise level by 8 decibels(for my project). Product very heavy 2 person install will make it easy. Product easy to work with otherwise. If hanging as a curtain you must use grommets. If product is to be visible take care handling it marks up easily.

This does not have a sticky back, but it is every bit 1LB MLV. Its heavy, arrived in good condition. Company was excellent due to a shipping error on my part during return.

2 YEAR OLD FOLLOW UP REVIEW. This item has started to disintegrate (become fragile, crack and chip apart easily) and the off gassing has gotten WORSE as it ages (smells like terrible fumes). Would not recommend this product.

home office use

My building is concrete but for some reason the doors are so thin, it's as if nothing is there (sound wise). I got this to replace some sound reducing curtains I had over the front door as I thought this would look much nicer (when covered with fabric) and would be more effective. Unfortunately its not nearly as effective as the curtains were. :/
