Review on 🔇 Design Engineering 050110 Under Carpet Lite: Ultra-effective Sound Absorption and Insulation, 24" x 70" for Enhanced Acoustic Comfort (11.6 sq. ft.) by Brent Rosecrans

I don't feel like giving a negative review because I like other DEI items but they led me to believe they had some sound deadening properties but that's on my simple tests does not happen. I have used most of the best sound and heat management products (all made in the USA) in various builds and needed thermal protection over the engine hatch, also was hoping for soundproofing but all of these can be helpful for those with moderate heat issues. , low sound absorption and decoupling, but I can see ZERO soundproofing performance. I would try to get my money back but I have already cut it. Oh, and money in the trash. I order Second Skin Liner Pro instead since the heat is low. Don't skimp on sound-absorbing materials!
