Is Spray-On Soundproofing Worth It Compared to Mats?
Sound deadening spray and soundproofing mats are two major choices that can be argued when it comes to silencing the cabin of a vehicle. Both products have the promise of a smoother, quieter ride, but each of them works in a different manner. Being aware of each one of their performances, their strong side, and their weak points, will allow you to make a decision that suits your vehicle and budget.
Spray-on soundproofing: It is a liquid coating that becomes hard after it is applied in a flexible layer. It operates by silencing vibrations on panels and wheel wells, and undercarriages. Owing to its spraying ability in areas that are difficult to reach, it is commonly applied in places where mats are inaccessible.
Soundproofing mats: On the other hand, there are heavy sheets which are generally composed of butyl rubber and aluminum foil that attach to flat metal surfaces such as door, trunk, and floor. They are shields which absorb and block vibrations at the origin.
Both methods help to eliminate unwanted noise, although evidence of their effectiveness vary according to their application location and method.
Spray vs Mat Soundproofing: Side-by-Side Comparison
Here’s a quick breakdown of how the two stack up:
Feature |
Spray-On Soundproofing |
Soundproofing Mats |
---|---|---|
Ease of Application |
Quicker for large, irregular, or hidden areas. |
Requires cutting, measuring, and pressing onto panels. |
Coverage |
Reaches tight corners, wheel wells, and underbody. |
Best for large flat panels like doors, floors, and trunk. |
Noise Reduction |
Good at mid-frequency noise and general vibration. |
Superior at blocking low-frequency tire, road, and engine noise. |
Durability |
Dependent on thickness and proper sealing. Some sprays add rust protection. |
Extremely durable once installed lasts the lifetime of the car. |
Weight Impact |
Very minimal weight added. |
Adds noticeable weight, but usually not enough to affect performance. |
Cost |
Lower upfront, though multiple coats may be needed. |
Higher cost, especially for full coverage, but stronger results. |
When a Spray Should Use
Car insulation spray shines in specific situations:
-
Covering wheel wells and underbody panels.
-
Reaching irregular surfaces where mats can’t stick.
-
Adding extra rust protection alongside soundproofing.
-
Drivers who want a lighter, budget-friendly upgrade.
On its own, spray-on soundproofing might not deliver a fully silent cabin, but as a supplement, it works exceptionally well.
When Mats Are the Better Choice
Soundproofing mats remain the go-to for heavy-duty noise reduction:
-
Best for drivers who want maximum quiet in the cabin.
-
Works wonders under carpets, in doors, and across the trunk.
-
Improves the performance of car audio systems by minimizing background noise.
Mats require more labor to install, but the payoff is clear: stronger sound blocking and long-term durability.
Smartest Approach: Combining Both
You do not necessarily need to decide between one or the other. A lot of car owners and professionals mix mats with spray-on soundproofing to achieve the best of both worlds. Mats absorb most of the road and tire noise on large panels, and sprays fill the gaps to make a layered system that produces the best results possible.
FAQs About Spray vs Mat Soundproofing
1. Does spray-on soundproofing really work?
Yes, it reduces vibrations and noise in targeted areas, but it’s most effective when paired with mats.
2. Which lasts longer: spray or mats?
Mats are generally more durable. Sprays can last long too, provided they’re applied correctly and in thick enough layers.
3. Is the weight from mats a problem?
Not for most vehicles. Even though mats are heavier, the added weight is minor compared to an SUV or sedan’s overall mass.
4. Can I apply spray and mats myself?
Yes. Sprays are not so complicated to use, whereas mats need time and appropriate location. Both are the subjects of many hobbyist projects.
