This Stuff Works!
Crutchfield Customer Review (What's this?)
I just took possession of my new 2016 Ford Transit Connect Cargo Van that I use for film production. I immediately installed Dynamat Extreme and Dynaliner throughout the entire interior. I created templates for every single cut in advance. The templates helped to dramatically speed up the installation process and reduce waste to virtually nil. Because the van is all black, I also opted to use 1/2" Dynaliner on the roof to reduce thermal heat transfer. I used 1/4" Dynaliner on all the metal body panels and body cavities (over Dynamat) and used 1/8" Dynaliner (over Dynamat) on the front driver and passenger doors behind the door panels. While I primarily used the Dynaliner to make the interior a little bit cooler during the summer months, I was impressed at how much it assisted in aiding additional sound deadening, a noticeable difference over just Dynamat alone. I also installed Dynamat and 1/8" Dynaliner on the back side of the metal bulkhead to stop an annoying vibration noise. I taped every seam and edge with Dyna Tape to prevent butyl seepage on my film gear and cases. I can't believe how much difference the Dynaliner made on all all black van in summertime. I would estimate it is 5 to 10 degrees cooler inside on hot days. Bargain hunters beware: Dynamat only warranties their products when purchased through authorized dealers. They don't sell their products on Amazon. Don't get taken by knock off products on the gray market.
Pros: Super easy to install. Further enhances sound deadening over using just Dynamat alone. Reduces thermal transfer of heat.
