How To Soundproof Rv

Have you ever wanted to enjoy a peaceful and quiet RV trip, but found yourself annoyed by the loud noises from the road, the engine, or the surroundings? If so, you are not alone.

Many RV owners and enthusiasts face the same problem and look for ways to reduce the noise level inside their vehicles.

Fortunately, there are some effective and affordable solutions that can help you soundproof your RV and make your travels more comfortable and relaxing.

The solution to soundproofing an RV is to use a combination of sound-absorbing materials, sound-blocking materials, and sound-dampening techniques. Sound-absorbing materials are those that can absorb or reduce the sound waves that hit them, such as foam, carpet, curtains, or blankets. Sound-blocking materials are those that can prevent or reflect the sound waves from passing through them, such as mass-loaded vinyl, rubber mats, or plywood.

Sound-dampening techniques are those that can reduce the vibration or resonance of the surfaces that produce or transmit sound, such as sealing gaps, adding insulation, or installing anti-vibration pads.

In this article, we will explain how to use these three types of solutions to soundproof different parts of your RV, such as the windows, the doors, the walls, the floor, the ceiling, and the engine compartment.

We will also provide you with some tips and tricks on how to choose the best materials and products for your specific needs and budget.

By following our guide, you will be able to create a quieter and more enjoyable RV environment for yourself and your loved ones.

Why Soundproof Your RV?

There are several key reasons why you may want to implement some soundproofing measures in your RV:

Reduce Outside Noises

Road noise, nearby campers, early morning activity at campsites – these types of external noises can easily penetrate the thin walls of an RV. Soundproofing will make a big difference in limiting the amount of outside noise you hear inside your RV.

Increase Privacy

By reducing noise transfer from inside your RV to the outside, soundproofing increases privacy. Keep conversations, phone calls, TV shows, and other interior noises from bugging your neighbors.

Improve Sleep Quality

Excess noise can make it hard to fall asleep and lead to interrupted sleep. Soundproofing eliminates disruptive noises, leading to better sleep.

Customize Your Environment

If you find certain noises stressful or distracting, you can target soundproof those specific areas. Customize the interior noise to create your ideal tranquil environment.

How To Soundproof Different Areas of the RV

The techniques for soundproofing an RV will vary depending on what area you are treating. Here are some of the main areas to consider when soundproofing an RV:

Cabover Bed Area

The cabover bed area is very vulnerable to road noise coming from the engine and tires. Applying sound deadener materials to the roof and bare metal frame around this area will reduce vibration and dampen noise. Mass loaded vinyl or dynamat mats are ideal for covering large surfaces like the ceiling. Seal any gaps around edges with acoustic caulk. Consider adding soft surfaces like carpet or cork boards to walls to further absorb sound.

Driver/Passenger Area

Use sound deadening mats on the floor, doors, ceiling and bare metal frame around the driver and passenger seats. Install higher density insulation in the doors. Apply acoustical sealant around windows and edges. Add some absorptive surfaces like upholstered panels to reduce reverberation.

Side Walls

The thin walls of an RV will benefit from adding mass loaded vinyl sheets and noise damping mats. Cover as much surface area as possible. Use spray foam or caulk around all edges, openings, and joints to seal gaps where noise seeps through. For even more sound blocking, apply MLV and then a decorative upholstered wall panel over top.

Slide Out Areas

Where slide out walls meet the main RV body, fill gaps with insulating foam sealant. Apply MLV sheets over walls and ceiling in slide out areas. Verify slide out is properly aligned and forms an airtight seal when closed.


Replace thin carpeting with a thicker rug pad and higher quality carpet or other flooring. Prioritize areas like the bedroom. Installing a floating floor is an even better option, as it isolates the floor from vibrations. Place cork, foam or rubber mats under appliances to reduce rattling and vibrations.

Windows and Doors

Apply acoustical sealant around all windows and doors. Upgrade door sweeps and weatherstripping to close gaps that allow noise intrusion. For windows, consider adding secondary acrylic windows panes or hanging a removable acoustical curtain. Solid core doors block more noise than hollow lightweight ones.


Apply sound deadener mats and MLV sheets to the ceiling. Spray foam insulates and reduces noise intrusion through roof vents, seams and openings. Cover Fan-Tastic vents with sound dampening vent covers. Sealant around roof air conditioners curbs will block noise.

Wheel Wells

Use high density spray foam or caulk to fill openings around wheel wells where noise intrudes. MLV sheets layered with mass loaded vinyl mats applied to the inside of wheel wells blocks noise that penetrates this area.

Best Soundproofing Materials for RV

Using the right materials is key to effectively soundproofing your RV. Products like mass loaded vinyl, sound damping mats, and acoustic insulations work well for DIY RV soundproofing:

Mass Loaded Vinyl (MLV)

MLV contains dense properties that block sound transmission. A thin 1 lb/sf MLV sheet adds mass and damping to reduce noise. Effective for walls, ceilings and wheel wells.

Sound Damping Mats

These flexible and lightweight mats (like Dynamat) absorb vibrations and dampen sound. They work well on uneven surfaces like floors, doors and sidewalls. Help constrain noise caused by rattling or vibration.

Acoustic Insulation

Insulation designed for audio applications improves sound absorption. Use in walls, floor and ceiling cavities to muffle noise from entering living spaces. Polyester fiber and recycled denim work well.

Acoustical Caulk and Sealant

Applied around openings, joints, windows, doors and edges, acoustical caulk seals gaps that allow noise intrusion and vibration transfer. Flexible when dry and simple to apply.

Closed Cell Spray Foam

Expanding spray foam insulates and blocks noise leaks. When sprayed into openings in walls, ceilings and floors, it seals gaps while dampening vibration. Most effective method for treating roof vents.

Sound Dampening Panels

Lightweight acoustic panels hung on walls absorb interior sound to reduce echo and reverberation. Panels made with rigid fiberglass or fabric wrapped insulation work best for RV use.

Combining these types of materials throughout the RV hits noise transmission from all angles. The mass loaded vinyl blocks sound, while caulk and seals restrict noise transfer through cracks. Absorptive insulation and panels prevent interior noise build up. Used together, they offer a comprehensive soundproofing solution.

DIY Soundproofing Tips and Tricks

Here are some handy tips to get optimal results from DIY soundproofing efforts:

  • Start by sealing all air leaks and openings with caulk or spray foam – this inexpensive step makes a big difference.
  • Use construction adhesive when applying damping mats and MLV sheets to ensure they bond tightly.
  • Overlap materials at the seams and cover all exposed edges to prevent noise flanking around soundproofing.
  • Layering different materials provides better sound blocking than a single material.
  • Isolate potential rattle sources like pictures or cabinets with rubber or foam.
  • Decouple wall hangings and screens from walls to reduce vibration transfer.
  • When applying panels, cover at least 80% of the wall or ceiling for noticeable sound absorption.
  • Cut mats and vinyl sheeting using utility knives with heavy duty blades or scissors to avoid fraying.
  • Higher density materials block more sound, but require thicker application to get the same coverage.
  • Work in small sections for easier handling and use roller to apply even pressure when bonding sheets.
  • Allow adequate drying time for adhesives and sealants before disturbing soundproofed areas.

Following these tips will achieve superior noise blocking and maximum sound absorption from DIY soundproofing projects.

Common Problem Areas to Address

Certain areas of RVs tend to be more problematic for excess noise. Focus soundproofing efforts on these common problem areas first:

Window and Door Openings

Gaps around windows, doors, hatches allow noise intrusion. Ensure a tight seal with high quality weatherstripping, door sweeps and acoustical caulk.

Roof Seams and Openings

Air conditioners, vents, skylights and seams where roof decking meets sidewalls often create noise leaks. Seal with spray foam and caulk.

Cabover Bed Area

The cabover bed area above driver compartment sees a lot of engine and road noise. Apply MLV sheets and sound damping mats here.

Wheel Wells

Openings allow noise into compartment. Seal with expanding spray foam and cover walls with MLV or sound damping mats.

Slide Out Joints

Gaps where slide outs meet main RV body can funnel noise inside. Seal with caulk/spray foam and place soundproofing materials inside slide out.


Replace carpeting with thicker pad and higher quality carpet or rugs. Add rubber mats under appliances.

Targeting these key areas first when applying soundproofing materials will make a big impact on reducing unwanted RV noise.
