Mass Loaded Vinyl (MLV) for Cars: Is It Worth It?

You've heard about mass loaded vinyl (MLV) and you're wondering if it's worth adding to your vehicle. Short answer: yes, if you want the best possible noise reduction. Here's why.

What is Mass Loaded Vinyl?

MLV is a thin, dense, flexible sheet material loaded with minerals (usually barium sulphate or calcium carbonate) that gives it exceptional mass per square metre. This mass is what blocks sound — the heavier the barrier, the more sound it stops.

MLV vs Sound Deadening Mats — What's the Difference?

• Sound deadening mats (CLD) reduce vibration in metal panels. They stop the panel itself from resonating.
• Mass loaded vinyl (MLV) blocks airborne sound from passing through. It stops noise transmission.

They do different things. For the best results, use both together — deadening on the metal first, then MLV on top.

Where to Use MLV in Your Vehicle

• Floor pans — blocks road and tyre noise coming up through the floor
• Firewall/bulkhead — stops engine noise entering the cabin
• Behind rear seats — blocks exhaust and road noise from the boot area
• Van bulkheads — essential in vans where the cargo area amplifies noise

Our MLV Products

Dodo Barrier Pro

Combines MLV with a closed cell foam layer for combined sound blocking and insulation. The foam layer adds thermal benefits and makes installation easier.

Dodo Barrier MLV

Pure mass loaded vinyl — maximum density for maximum sound blocking. Use when you want the highest possible noise reduction and will add insulation separately.

Both available at our MLV collection.

Is MLV Worth the Investment?

If you've already applied sound deadening mats and want to take noise reduction to the next level, MLV is the logical next step. It targets the airborne noise that deadening alone can't fully address.

For campervan and motorhome builds, MLV on the bulkhead is almost essential — the engine compartment is right next to your living space.

For car audio builds, MLV helps create a quieter cabin so you can hear your music at lower volumes with better clarity.
