If you’re considering Noico 80 mil sound deadener for your car, the key question isn’t simply whether Noico is “good.”
The better question is whether a butyl vibration-damping mat is the right solution for the noise problem you’re trying to fix.
Quick verdict: Noico 80 mil is a practical choice for DIYers who want to reduce vibration and resonance in vehicle sheet metal without automatically moving to a premium-priced damping system. It works particularly well on doors, floors, trunks, roofs and other resonant metal panels when it is properly installed.
However, Noico is not a complete soundproofing system by itself. It controls vibrating panels. If your main problem is airborne tire noise, exhaust noise, heat or trim rattles, other material types may also be needed.
The SPD approach is simple: diagnose the noise path first, then choose the material that actually addresses it.
Noico 80 Mil Review Quick Verdict
Choose Noico 80 mil if:
- You want to reduce resonance in metal vehicle panels.
- You are completing a DIY door, floor, trunk or roof treatment.
- You want a butyl-based self-adhesive damping mat.
- You prefer a product that can be cut into manageable sections.
- You are prepared to clean the surface properly and roll the material firmly during installation.
Look beyond Noico alone if:
- Your main problem is airborne tire or exhaust noise.
- You need substantial thermal insulation.
- You are trying to stop wind noise caused by seals or gaps.
- You want to eliminate trim-on-trim rattles rather than panel vibration.
- You expect one layer of damping mat to make the entire vehicle quiet.
Overall: Noico makes the most sense when you treat it as a vibration damper first, not as a universal soundproofing product.

80 mil does not mean 80 millimeters.
It means approximately 0.08 inches, or 2 millimeters.
What Does Noico Sound Deadener Actually Do?
Noico 80 mil is designed primarily to reduce vibration and resonance in vehicle panels.
Large areas of relatively thin metal can flex and resonate when excited by:
- Road vibration
- Tires
- Speakers
- Engine and drivetrain vibration
- Impact from rain or debris
A butyl damping mat bonds directly to the metal and changes the way that panel vibrates.
This can help reduce:
- Panel resonance
- Metallic vibration
- Buzzing and rattling associated with vibrating panels
- Some of the noise contribution created by resonating bodywork
It can also create a more stable mounting environment around car-audio speakers.
But this is different from blocking airborne sound.
If tire, exhaust or engine noise is passing through the vehicle structure as airborne sound, a heavier barrier or another complementary material may be needed.
For a broader explanation of the different material types, see our guide to automotive sound-deadening products.
What Most Noico Reviews Miss
Many Noico reviews focus on three things: thickness, price and how easy it is to stick the material onto a car.
Those factors matter, but they don’t answer the most important question:
Is a vibration-damping mat actually the material your vehicle needs?
If a door skin rings when tapped, a floor pan resonates or a trunk panel vibrates with the audio system, damping material is a logical first treatment.
If the problem is wind leaking around a door seal, however, putting more Noico on the floor will not repair the leak.
If the dominant problem is low-frequency road or exhaust noise, damping the metal may reduce one part of the problem without solving the entire transmission path.
And if two plastic trim pieces are rubbing together, a decoupling material may be more appropriate.
That is the decision advantage with Noico: use it where vibration is the problem rather than covering the entire vehicle simply because the product is available.
Noico 80 Mil Pros and Cons
Noico Pros
- Butyl-based automotive damping construction.
- Useful 80 mil / 2 mm thickness for vehicle panel treatment.
- Self-adhesive installation.
- Can be cut into sections for irregular vehicle surfaces.
- Embossed foil provides a visual installation indicator when rolled smooth.
- 36 sq ft pack suits many medium-size DIY projects.
- Can be installed on several common interior vehicle panels.
Noico Cons
- It adds weight to the vehicle.
- A roller is still needed for proper installation.
- Large jobs require substantial interior disassembly.
- It is not a complete airborne-noise barrier.
- It should not be treated as a dedicated thermal-insulation layer.
- Correct surface preparation takes time.
Where Does Noico Work Best?
Noico is most useful where a rigid metal panel is contributing vibration or resonance.
Common locations include:
- Car doors
- Floor pans
- Trunks and cargo areas
- Rear quarter panels
- Roofs
- Rear decks
- Speaker mounting areas
- Suitable firewall areas
That does not mean every exposed surface should automatically be covered.
Prioritize the panels that are most relevant to the problem you’re solving.
Noico for Car Doors
Doors are one of the most logical places to use a vibration-damping mat.
The outer door skin is a large sheet-metal panel that can resonate from road input and from a door-mounted speaker.
Applying Noico to suitable sections of the metal can reduce that resonance and help control rattles associated with panel vibration.
Take care around:
- Window regulators
- Door-lock mechanisms
- Wiring
- Drain holes
- Side-impact structures
- Airbag components where fitted
For a detailed installation sequence, see our DIY car door damping guide.
Noico for Floors
Vehicle floors contain broad sheet-metal areas and can be a useful target when structural vibration contributes to cabin noise.
The downside is installation effort.
A comprehensive floor treatment may require removing:
- Seats
- Carpet
- Lower trim
- Parts of the center console
- Seatbelt hardware
That means the difficult part is usually not applying the Noico. It is accessing and safely reassembling the vehicle.
If you’re planning a floor installation, our car floor damping installation guide explains the general preparation, cutting, rolling and reassembly process. The same basic surface-preparation principles apply to comparable self-adhesive butyl damping mats.
Noico for Trunks and Cargo Areas
Trunks often contain a combination of:
- Broad floor sections
- Wheel wells
- Rear quarter panels
- Trunk lids
- Irregular structural sections
These areas can contribute resonance, especially where rear tires or a powerful audio system introduce significant energy into the structure.
For a complete treatment strategy, see our car trunk soundproofing guide.
Can Noico Improve Car Audio?
It can help in the right way.
A speaker mounted in a vibrating door or rear panel is working against a structure that can flex, buzz and resonate.
Damping that panel can create a more stable acoustic environment and reduce unwanted vibration around the speaker.
That does not mean Noico increases the power of the audio system or acts as an acoustic absorber by itself.
Its contribution comes primarily from controlling the surrounding structure.
Does Noico Reduce Road Noise?
Yes, potentially, but with an important limitation.
Road noise inside a vehicle can come from several mechanisms:
- Vibrating sheet metal
- Tire noise
- Suspension vibration
- Airborne sound
- Wind leakage
- Trim rattles
Noico can reduce the contribution from resonating metal panels.
It cannot automatically solve all of the other paths.
This is why a successful quiet-car build may use several material types rather than multiple layers of the same damping mat.
Does Noico Insulate Against Heat?
Noico 80 mil should not be treated as your main thermal-insulation product simply because it uses butyl and foil.
Its primary role is damping vibration.
If heat control is an important part of the project, use a material specifically intended for thermal insulation where appropriate and where the vehicle has enough clearance for the additional layer.
This is more effective than expecting one damping mat to perform every job equally well.
How Much Noico Do You Need?
There is no universal percentage of vehicle coverage that is correct for every project.
The old version of this article suggested that covering around 40% of the interior would automatically be enough. That is too simplistic.
The amount you need depends on:
- The panel you’re treating
- The size of the vehicle
- The source of the vibration
- Whether you want targeted or comprehensive treatment
- How much weight you’re willing to add
- Whether other material layers will also be installed
For targeted resonance control, treating the most active sections may be enough.
For a more comprehensive interior build, substantially more material may be used.
The 36 sq ft Noico pack is therefore best viewed as a quantity of material to allocate according to your project rather than a guaranteed percentage of whole-car coverage.
How to Install Noico 80 Mil
The basic installation process is straightforward, but good preparation matters.
- Choose the panel you want to treat.
- Remove the necessary trim or interior components.
- Inspect the surface for rust, moisture, wiring and service points.
- Vacuum away dirt and debris.
- Degrease the metal with an appropriate residue-free cleaner.
- Measure and test-fit the Noico sheet.
- Cut the material to shape.
- Peel back part of the release liner.
- Position the material carefully.
- Gradually remove the remaining liner while pressing the mat onto the panel.
- Roll the material firmly until the embossed foil pattern is flattened appropriately.
- Check the edges and contours.
- Reinstall the vehicle trim.
Do not skip the roller.
The goal is firm adhesive contact with the panel underneath, not simply making the sheet look attached.
For a more detailed walkthrough, see our general automotive sound-deadening installation guide.
Common Noico Installation Mistakes
Installing Over Dirty Metal
Dust, oil and residue can interfere with adhesive contact.
Covering Rust or Moisture Problems
Repair corrosion or water intrusion before installing damping material.
Skipping the Roller
Hand pressure alone may not create consistent contact across the full surface.
Covering Drainage Openings
Doors and other vehicle structures may contain drainage paths that must remain open.
Covering Mounting Points
Keep seat, seatbelt, trim, electrical-ground and service mounting points accessible.
Using Noico as a Complete Sound Barrier
A damping mat solves a different problem from a heavy airborne-noise barrier.
Automatically Adding Multiple Layers
If the first damping layer has already controlled the panel, adding more damping material may be less useful than addressing the remaining noise path with a different material.
Noico vs More Expensive Sound Deadeners
Price alone should not determine which damping material you buy.
When comparing Noico with another brand, look at:
- Material construction
- Thickness
- Weight per square foot
- Total coverage
- Sheet dimensions
- Installation requirements
- Foil durability
- Adhesive behavior
- Product documentation
- Total project cost
A more expensive product is not automatically the correct solution, and a thicker-looking product is not automatically the better damper.

Is Noico 80 Mil Worth It?
For the right project, yes.
Noico 80 mil makes sense for a DIYer who:
- Has identified resonating metal as part of the noise problem.
- Wants a self-adhesive butyl damping mat.
- Is willing to remove trim and prepare the panel properly.
- Understands that installation quality matters.
- Doesn’t expect one product to solve every type of automotive noise.
It becomes a weaker choice if you’re buying it primarily because you expect a single layer to:
- Block all road noise
- Stop wind noise
- Provide complete thermal insulation
- Replace a heavy acoustic barrier
- Fix loose or rubbing trim by itself
SPD’s approach is therefore not to ask whether Noico is “good” in isolation. Ask whether Noico’s damping function matches the panel and noise source you’re dealing with.
Noico Sound Deadener FAQ
How thick is Noico 80 mil?
Noico 80 mil is approximately 0.08 inches or 2 millimeters thick. It is not 80 millimeters thick.
What is Noico made from?
Noico 80 mil uses a self-adhesive butyl damping layer with a foil facing.
Is Noico a soundproofing material?
It is better described as an automotive vibration-damping material. It can reduce resonance that contributes to perceived vehicle noise, but it is not a complete airborne-sound barrier by itself.
Can I install Noico myself?
Yes. Straightforward panel treatment is suitable for many competent DIYers, although accessing the underlying metal can require significant disassembly.
Do I need a roller for Noico?
Yes, a firm installation roller is strongly recommended. The embossed foil pattern is intended to be rolled down as the material achieves proper contact with the surface.
Can Noico be installed on car doors?
Yes, suitable metal door surfaces are a common application. Keep drainage openings, mechanisms, wiring and safety components unobstructed.
Can Noico be installed under carpet?
Yes, it can be installed on suitable metal floor panels beneath the interior, provided mounting points, wiring, drainage and trim clearance are properly managed.
Can Noico stop road noise?
It can reduce the portion of road noise associated with resonating body panels. Other transmission paths may require additional materials or repairs.
Does Noico help with speaker rattles?
It can reduce vibration in the metal surrounding a speaker, which may help control panel resonance and rattles. Loose trim or hardware should still be fixed separately.
Do I need 100% coverage?
Not necessarily. Coverage should be based on the panel, objective and complete treatment plan rather than an arbitrary percentage.
Is thicker sound deadener always better?
No. Thickness is only one characteristic. Material formulation, mass, constraining layer, adhesion and installation quality also matter.
Final Verdict
Noico 80 mil remains a useful automotive damping option when the problem is panel vibration and resonance.
Its 2 mm butyl-and-foil construction, self-adhesive format and manageable sheets make it suitable for DIY treatment of doors, floors, trunks, roofs and other appropriate metal panels.
The biggest mistake is expecting too much from it.
Noico is not automatically a substitute for thermal insulation, decoupling foam, a heavy sound barrier, new weather seals or mechanical repairs.
Use it where damping is actually required, install it carefully, and add other material types only when the remaining noise path justifies them.
That is the SPD approach: diagnose the problem first, then use the simplest material that properly addresses it.
Good luck and happy soundproofing!
