Excellent Sound Deadening Material!
I installed Kilmat Sound Deadening in my truck, and I’m extremely impressed with the results. The material is thick, pliable, and easy to cut to fit doors, floor panels. It sticks very well to metal surfaces and doesn’t peel, even after heating it slightly to make it more flexible. After installation, I immediately noticed a reduction in road noise and vibrations. Worth the money!!

Great sound insulation.
The 36 Sqft. Was enough to do two trunks, a Mazda 3 and Civic Si. Cutting to size was easy with a ruler and box cutter. I like how each sheet has small squares indented into them which helps out alot when measuring the exact size i want. Adhesion is of high quality. Sound quality is very noticeable, i hear less road noise which is the number one reason i bought it. I have yet to test out for heat isolation and temperature control.

Good stuff!
Really good product for the price, I used it on the doors in my 2008 civic SI. It sticks really well and does a good job of deadening vibrations and adding mass. It forms to things and cuts well, but still holds enough of a shape to not seem floppy or cheap. The doors seem a lot more solid and sound good when they close compared to before.

Great sound deadening
Good quality. Easy to cut, easy to apply. Rolls on easy. Good adhesive. Lowered the cabin road noise in my Mustang and lowered the cabin db of the exhaust. Installed with a full custom audio system. Would purchase again.

Good value, but stinky
Easy to apply. Good value. Smells like tar.

Greaty Quality and Real Results
I used this in my 2rd gen Cummins. I had always heard about the added weight and whatnot (not that it matters in a diesel truck), but it wasn't overly heavy to me. I did a crew cab truck with 1.5 boxes, so the coverage per box is solid. It's easy to work with and adheres very well. I can tell a big difference from the cab drone now vs before, also a lot less rattles and shakes. Very glad I decided to do it.

Worth the time and money
I removed the resonator from my 2000 Monte Carlo. I love the sound of the pipes, but it was very noisy inside was terrible. Kilmat made a huge difference in the noise. It was work to put down, but it stuck down excellently. It wasn't really to do, just work

Amazing Product for Audio Enthusiasts
Amazing and high quality that sticks very well. Sound deadening is amazing with this, just make sure you use enough layers by doing the “knock” test. I had to use 4 layers inside the area near the wheel well because it was very hollow and this product solved the issue. Subwoofers in the trunk sound great and much more cleaner instead of ghetto trunk rattle.

Il segreto per far suonare davvero bene le nuove casse: Addio vibrazioni e "effetto lattina"
Ho acquistato il KILMAT da 2mm (pacco da 1,7 mq) per insonorizzare le portiere della mia Renault Clio 2 mentre sostituivo gli altoparlanti. Sapevo che su un'auto datata le lamiere tendono a vibrare molto con i bassi, e questo prodotto ha risolto il problema alla radice. Applicazione e Lavorabilità: Facilità d'uso: I fogli sono maneggevoli e si tagliano facilmente con un taglierino o forbici robuste. Il butile è morbido e non serve scaldarlo con la pistola termica (a meno che non faccia gelido fuori), aderisce subito fortissimo. Copertura: Con 1,7 mq sono riuscito a fare abbondantemente le due portiere anteriori (strato interno ed esterno) e mi è avanzato qualcosa per il portellone del bagagliaio dove ho il subwoofer. Indicatore visivo: La goffratura (la trama a quadratini) sull'alluminio è geniale: quando passi il rullino per farlo aderire, la trama si appiattisce. Così sai esattamente dove hai pressato bene e dove no. Risultati: La differenza è impressionante. Audio: I bassi delle mie nuove casse sono molto più "secchi" e precisi, perché l'energia non si disperde nel far tremare la portiera. Comfort: Quando chiudo la portiera ora si sente un rumore sordo ("Thud") da auto di lusso, invece del vecchio rumore di lamiera vuota ("Sbleng"). Anche in autostrada entra meno rumore dall'esterno. PRO: ✅ Rapporto Qualità/Prezzo: Costa decisamente meno dei marchi blasonati (come Dynamat) ma fa lo stesso identico lavoro. ✅ Nessun odore: Temevo che puzzasse di catrame o chimico, invece è assolutamente inodore, ottimo per l'abitacolo. ✅ Adesione: Una volta attaccato, non si stacca più. CONTRO: ❌ Bordi taglienti: L'alluminio è sottile ma tagliente come un rasoio sui bordi appena tagliati. Usate assolutamente i guanti durante la posa o vi ritroverete le mani piene di taglietti senza accorgervene. ❌ Rullino non incluso: Per applicarlo bene serve un rullino pressore (roller) che va comprato a parte, ma è indispensabile. Verdetto: Se state cambiando le casse all'auto, dovete prendere questo. È l'upgrade che fa la differenza tra un impianto amatoriale e uno che suona bene. Soldi spesi benissimo per il comfort acustico.

Great option for beginner audio enthusiasts
I purchased this for insulating both my door panels and the back of the door cards during my audio system install. I'm no expert, but this product was easy to cut, easy to install and had noticeable results. Road noise was reduced vastly, which was the main goal for this project.
