Noico vs Kilmat: Which Car Sound Deadener Should You Choose?

If you’re choosing between Noico and Kilmat for car sound deadening, the decision is closer than many comparisons make it seem.

For an apples-to-apples comparison, Noico Black 80 mil and Kilmat 80 mil are both 2 mm-thick butyl-based sound deadening mats, and comparable packs cover 36 sq ft. The biggest practical differences are therefore not thickness, but sheet size, handling, installation preference, and current price.

Noico vs Kilmat: Quick Verdict

For most DIY installations, there isn’t a dramatic performance specification separating comparable 80 mil Noico and Kilmat mats.

Choose Kilmat if:

You prefer working with smaller pieces.
You’re installing around doors, wheel arches, curves, or awkward contours.
Kilmat offers the lower current cost per square foot when you buy.

Choose Noico if:

You prefer larger sheets for covering floors, trunks, roofs, and other broad areas.
You like Noico’s embossed foil installation indicator.
Noico offers the better current price per square foot.

Overall: I wouldn’t choose Noico over Kilmat simply because one is supposedly thicker. When comparing equivalent products, both are available at 80 mil / 2 mm. Your installation area, sheet preference, and current price are more useful deciding factors.

The important distinction is that Noico Black 80 mil should be compared with Kilmat 80 mil. Noico also sells thicker insulation products, but those are not equivalent products and shouldn’t be used to make Noico’s standard sound deadener appear thicker than Kilmat.

Noico Black 80 Mil

Noico Black is a self-adhesive butyl and foil automotive sound deadening mat.

The 36 sq ft version is 80 mil (2 mm) thick and comes in nine folded sheets measuring approximately 29.5 × 19.5 inches each.

That relatively large sheet format can be useful when covering broad vehicle surfaces such as:

Floors
Trunks
Roofs
Cargo areas
Large door sections

Larger pieces mean fewer individual sections to position, although they may require more cutting when working around tight curves and complicated shapes.

Noico also uses an embossed pattern on the foil. During installation, the pattern helps indicate whether the material has been properly rolled onto the metal surface.

Noico Pros

80 mil / 2 mm butyl construction.
Large sheets can make broad-area coverage quicker.
36 sq ft pack available.
Self-adhesive installation.
Embossed foil helps indicate whether the mat has been rolled down properly.
Suitable for DIY automotive installations.

Noico Cons

Larger sheets can require more cutting around complex vehicle contours.
A roller may need to be purchased separately.
Current pricing can change, so it isn’t automatically the cheaper option.

Kilmat 80 Mil

Kilmat is another butyl-based automotive sound deadening mat aimed heavily at the DIY market.

Its comparable 80 mil product is also 2 mm thick, and the commonly compared pack covers 36 sq ft.

One of Kilmat’s practical differences is its use of smaller individual sheets. That can make installation easier when you’re working inside doors, around wheel wells, underneath trim, or across surfaces with lots of curves and recesses.

Instead of wrestling with a large piece and cutting it repeatedly, smaller sheets can be positioned individually.

Kilmat Pros

80 mil / 2 mm butyl-based construction.
36 sq ft pack available.
Smaller pieces can be easier to position around complex areas.
Self-adhesive.
Well suited to DIY installation.
Often positioned as a budget-conscious automotive sound deadener.

Kilmat Cons

Covering large flat areas may require more individual pieces than Noico’s larger-sheet format.
More pieces also means more joins.
Price varies, so Kilmat shouldn’t automatically be assumed to be cheaper.

Which Is Easier to Install: Noico or Kilmat?

Both products follow essentially the same installation process:

Remove interior trim where necessary.
Clean and degrease the metal surface.
Measure and cut the material.
Peel away the backing.
Position the mat against the panel.
Roll it firmly onto the metal to achieve good contact.
Refit the vehicle trim.

The difference is mainly how you prefer to work.

Kilmat May Be Easier for Complicated Areas

Smaller sections can be convenient around:

Door interiors
Wheel arches
Transmission tunnels
Corners
Curves
Narrow spaces

You can work piece by piece rather than trying to shape one large sheet.

Noico May Be Easier for Large Surfaces

Noico’s larger sheets may make more sense when covering:

Floors
Trunk floors
Roofs
Cargo areas
Larger flat panels

You may be able to cover more surface with fewer joins.

Neither approach is automatically better. It depends on where you’re installing the material.

For the complete process, see our guide on how to install automotive sound deadening material.

Is Noico Thicker Than Kilmat?

Not when comparing Noico Black 80 mil with Kilmat 80 mil.

Both are approximately:

80 mil / 0.08 inch / 2 mm

This is worth clarifying because Noico also sells separate products with greater thicknesses, including heat and insulation products.

Those products shouldn’t be compared directly with an 80 mil butyl vibration-damping mat simply because they carry the Noico brand name.

If you’re deciding between these two sound deadeners, compare equivalent products rather than comparing Kilmat’s 80 mil mat with an unrelated thicker Noico insulation layer.

Which Is Better for Reducing Car Noise?

Both products are primarily used to dampen vibration and resonance in vehicle panels.

Applied to metal surfaces such as doors, floors, trunk panels, and roofs, butyl damping material helps reduce the tendency of those panels to vibrate and resonate.

It’s important, however, not to treat an 80 mil damping mat as a complete soundproofing system.

If your goal is a substantially quieter vehicle, particularly against airborne road, tire, or exterior noise, a broader treatment may involve additional layers or materials depending on the area being treated.

For more on the role of different automotive soundproofing layers, see our guide to automotive sound barriers and their benefits.

So when comparing Noico and Kilmat, I wouldn’t declare one the clear winner for noise reduction purely from their nominal thickness. At 80 mil versus 80 mil, the specification itself doesn’t give either product that advantage.

Noico vs Kilmat for Car Doors

For doors, Kilmat’s smaller-sheet format may be more convenient.

Car doors contain:

Wiring
Braces
Speakers
Access holes
Curved surfaces
Window mechanisms

Smaller sections can therefore be easier to position without excessive cutting.

That doesn’t mean Noico won’t work in doors. It simply means its larger sheets may need to be cut into smaller pieces first.

Our pick for ease of handling in doors: Kilmat.

Noico vs Kilmat for Floors and Trunks

For broad, comparatively flat areas, the balance shifts.

Noico’s larger sheets can reduce the number of individual pieces needed when covering a trunk or vehicle floor.

Fewer pieces may make layout simpler and reduce the number of joins across a large area.

Our pick for convenient broad-area coverage: Noico.

Which Is Better Value?

Don’t judge this by the advertised pack price alone.

Because comparable Noico and Kilmat packages are available with 36 sq ft of coverage, the simplest comparison is:

Pack price ÷ 36 = cost per square foot

For example, if one product costs $72 and the other costs $90:

$72 ÷ 36 = $2.00 per sq ft
$90 ÷ 36 = $2.50 per sq ft

Prices change frequently, especially on Amazon, so checking the current cost per square foot gives you a much more useful comparison than permanently labeling one brand the cheaper option.

Noico vs Kilmat FAQs

Is Noico Better Than Kilmat?

Not across the board. Comparable Noico Black and Kilmat products are both available at 80 mil / 2 mm thickness and 36 sq ft coverage.

Kilmat may be more convenient when working around detailed or awkward areas, while Noico’s larger sheets may be preferable for covering broad surfaces.

Price can also determine which provides better value at the time you buy.

Is Kilmat Thinner Than Noico?

Not in an equivalent 80 mil comparison.

Noico sells other, thicker insulation products, but Noico Black 80 mil and Kilmat 80 mil are both approximately 2 mm thick.

Can You Use Noico or Kilmat on Car Doors?

Yes. Both types of butyl sound deadening mat can be installed on suitable metal surfaces inside vehicle doors.

Take care not to obstruct drainage holes, wiring, moving window components, locks, or other mechanisms.

Do I Need a Roller?

A roller is strongly recommended for this type of installation because the mat needs firm, consistent contact with the metal surface.

Noico specifically uses its embossed foil pattern as an installation indicator: rolling the pattern flatter helps show that sufficient pressure has been applied.

Is Noico or Kilmat Better for a Trunk?

Both can work, but Noico’s larger sheets may be convenient across broad trunk panels and floors.

Is Noico or Kilmat Better for Doors?

Kilmat’s smaller pieces may make it easier to work around the irregular shapes and mechanisms commonly found inside doors.

Noico vs Kilmat: Final Verdict

Noico and Kilmat are more alike than different when you compare equivalent 80 mil products.

Both offer:

80 mil / 2 mm thickness
Butyl-based construction
Foil facing
Self-adhesive installation
36 sq ft package options
DIY-friendly automotive use

The most useful difference is the way the material is supplied.

I’d choose Kilmat for doors and complicated contours where smaller pieces make positioning easier.

I’d lean toward Noico for large floors, trunks, and other broad surfaces where larger sheets can reduce the number of pieces required.

For overall value, check the current price per square foot before buying. Neither product should automatically be called the cheaper or better choice without comparing today’s pricing.

Most importantly, don’t choose Noico because you’ve read that it is 150 mil while Kilmat is only 80 mil. That’s mixing different product types. For the comparable sound deadening mats covered here, Noico Black and Kilmat are both 80 mil / 2 mm products.

Ultimately, the better choice is the one that fits your installation area, preferred sheet size, and current budget.
