7 Best Soundproofing Kits For Camper Vans That Create Total Serenity
Your guide to creating a quiet oasis on wheels.
The first time you merge onto a highway in your newly built camper van, the reality hits you. It’s not the gentle hum of a passenger car; it’s a roaring, rattling cacophony. Every bump, every gust of wind, every passing truck echoes through the giant metal box you now call home.
This is why soundproofing isn’t a luxury in a van conversion; it’s a fundamental component of a livable space. A quiet interior reduces driving fatigue, makes conversations possible without shouting, and transforms a noisy campsite into a peaceful sanctuary. It’s the invisible layer that separates a stressful vehicle from a serene home.
Choosing the right materials can feel overwhelming, with a dozen brands all claiming to be the best. The key is understanding that you’re not just buying a product; you’re building a system. You need to tackle both panel vibrations and airborne noise, and different products are designed for each specific job.

Kilmat 80 Mil: Your Best Budget Sound Deadener
Reduce noise and improve audio quality in your car with KILMAT sound deadening. This easy-to-install, self-adhesive butyl mat features an indicator to ensure correct application for maximum sound insulation.
Kilmat has become the go-to for van builders who need effective results without a premium price tag. This is a classic constrained layer damper (CLD), a butyl rubber mat with a foil backing. Its entire job is to add mass to your van’s thin metal panels, stopping them from vibrating like a drum skin as you drive.
Application is straightforward: cut, peel, stick, and roll it on firmly. A good roller is non-negotiable here; proper pressure is what ensures the butyl fully adheres to the metal and does its job effectively. Don’t skip the rolling, or you’ll be leaving performance on the table.
The trade-off for the low price is minor. It can have a slight asphalt-like smell that dissipates after a few days, and it’s a bit heavier than premium alternatives. But for killing the most offensive road rattles and structural noise on a budget, Kilmat offers an unbeatable value proposition.
Noico 80 Mil: The Top All-Around Performer
Enhance your vehicle's acoustics with Noico 80 mil sound deadening mat. This 36 sqft butyl mat offers superior noise insulation and dampening, featuring a strong adhesive and an installation indicator for professional results.
If you can stretch your budget just a bit, Noico 80 Mil represents the perfect middle ground. It delivers a noticeable step up in quality and user-friendliness from the most basic options. It’s a favorite in the van community for good reason—it just works, and it works well.
One of its best features is the embossed foil backing, which acts as a built-in installation indicator. As you press it down with a roller, the pattern flattens out, giving you visual confirmation that you’ve achieved proper adhesion. This is a massive confidence booster, especially for first-time builders.
Noico provides a fantastic balance of performance, cost, and ease of use. It’s not as lightweight as the high-end pro options, but it’s a reliable workhorse that will dramatically quiet your ride. For most van builds, this is the sweet spot where cost and performance intersect perfectly.
HushMat 10200: Easiest Install for Your Van
For the builder who values their time and sanity, HushMat is the answer. Its standout feature is an incredibly forgiving and aggressive adhesive. It’s designed to stick reliably in a huge range of temperatures, from a freezing winter morning to a sweltering desert afternoon.
This directly translates to a faster, less frustrating installation. Unlike many other deadeners that require a perfectly clean, solvent-wiped surface, HushMat only needs to be applied to a dust-free panel. This can easily save you hours of tedious prep work, a gift when you’re in the middle of a complex build.
While its primary function is sound deadening, it also provides a modest amount of thermal insulation. The cost is higher than budget mats, but you’re paying for convenience and a top-tier adhesive. If a quick, no-fuss application is your top priority, HushMat is worth the investment.
FatMat Rattletrap: Max Coverage for Your Rig
Reduce noise and distortion in your car, boat, or home with FatMat Rattletrap sound deadener. This self-adhesive, 80-mil insulation features a "Super-Stick" adhesive and includes an install kit for easy application.
When you’re staring at the vast, empty interior of a Sprinter or a Promaster, the sheer square footage can be intimidating. This is where FatMat Rattletrap shines. It’s often sold in large, cost-effective rolls designed to provide maximum coverage for a reasonable price.
FatMat gives you options, coming in several thicknesses so you can tailor your application. You might use the super-thick 100 mil version on the noisy wheel wells and floor, then switch to a lighter 50 mil for the ceiling. Many of their kits also come bundled with a roller and knife, which is a convenient touch.
It’s important to note that some users report a stronger initial odor compared to pure butyl products. However, if your main goal is to add a lot of mass to a very large, resonant vehicle, FatMat provides the bulk needed to tame the beast without completely emptying your wallet.
Dynamat Xtreme: The Pro Choice for Your Build
Reduce unwanted noise and vibration in your vehicle with Dynamat Xtreme. This easy-to-install, self-adhesive pack contains 36 sq ft of sound deadening material, perfect for floors, doors, and more.
Dynamat is the brand that started it all, and it remains the benchmark for professional-grade performance. It’s the product you’ll find in high-end audio builds and professional van conversions where no compromises are made. The name itself is synonymous with sound deadening.
What sets it apart is the material science. Dynamat uses a proprietary lightweight butyl composite and a thick, annealed aluminum layer that is exceptionally efficient at converting vibration into low-level heat. This means it can achieve the same or better results with a thinner, lighter product than many of its competitors.
Of course, this level of engineering and brand recognition comes at a cost. Dynamat is a premium product with a premium price. For the builder creating their ultimate dream rig or anyone who demands the absolute best acoustic performance, it’s an investment in pure, uncompromised quiet.
Second Skin Damplifier Pro for Premium Results
Reduce car noise and vibration with Damplifier Pro sound deadening mats. These USA-made butyl rubber tiles feature a heat-resistant foil layer for superior sound dampening and thermal insulation.
In the world of high-performance sound deadening, Second Skin is Dynamat’s fiercest competitor. It’s an American-made, enthusiast-grade product that focuses on raw performance above all else. If you’re the type of builder who researches every technical spec, Second Skin is likely on your radar.
Damplifier Pro boasts an incredibly thick foil layer and a high-temperature butyl adhesive, making it exceptionally effective at damping vibration. It’s designed to perform in the most demanding environments, from engine firewalls to floor pans directly above the exhaust. This robust construction ensures it won’t fail, even in the hottest climates.
Choosing between Second Skin and Dynamat is often a matter of brand loyalty or specific project needs. Second Skin prides itself on its technical data and customer support, appealing to the meticulous builder. It’s an uncompromising choice for those who want to build their van’s soundproofing system to the highest possible standard.
3M Thinsulate: Your Thermal & Sound Solution
Now, let’s talk about the second part of the equation. While butyl mats handle vibration, 3M Thinsulate tackles airborne noise and temperature. This is not a sound deadener; it’s a sound absorber and thermal insulator, and it’s a critical component of a truly quiet van.
Thinsulate works by trapping air molecules, which slows the transfer of both heat and sound waves. It’s incredibly lightweight, hydrophobic (it won’t absorb water or support mold growth), and easy to install in wall cavities. This is what quiets the roar of passing traffic, the howl of the wind, and the patter of rain on the roof.
You do not choose Thinsulate instead of a butyl mat—you use it in addition to one. The professional approach is a two-stage system: first, apply a deadener like Noico or Dynamat to the metal panels. Then, fill the cavities with 3M Thinsulate. This combination is what creates true serenity.
How to Choose Your Perfect Soundproofing Kit
The most important takeaway is that soundproofing is a system, not a single product. You are fighting two different enemies: structural vibration and airborne noise. A butyl mat (CLD) is your weapon against vibration, while a fibrous insulation like Thinsulate is your shield against airborne sound.
Here’s a simple framework to guide your decision:
- On a Tight Budget? Start with Kilmat or Noico on the largest, flattest panels—doors, wall panels, and especially the wheel wells. Even 25% coverage here makes a huge difference.
- Prioritizing Speed? HushMat will save you hours of prep time, getting you back to the rest of your build faster.
- Seeking Ultimate Performance? A system combining Dynamat or Second Skin on the panels with a complete layer of 3M Thinsulate in the cavities is the gold standard for a whisper-quiet ride.
Don’t get bogged down by the idea of 100% coverage. Focus your efforts on the areas that resonate the most. A strategic application of the right materials is far more effective than a sloppy, full-coverage application of the wrong one. Your goal is a peaceful space, and a smart system is the surest way to get there.
Ultimately, the effort you put into soundproofing your van pays you back every single day. It’s the difference between an exhausting drive and a pleasant journey. It’s the ability to enjoy a quiet morning coffee while a storm rages outside. It’s the foundation of a comfortable, peaceful mobile home.
This isn’t just about adding materials to a vehicle; it’s about fundamentally changing the character of your living space. By choosing the right combination of products for your goals and budget, you can transform a rattling cargo van into a serene sanctuary on wheels. That peace and quiet is one of the best investments you can make in your life on the road.
