26358 reviews
KILMAT 50 mil Car Sound Deadening Mat is a solid choice for anyone looking to reduce noise in their vehicle. Made from butyl and foil, this mat boasts a thickness of 1.3 mm, which is effective at handling road noise and vibrations. One of its main strengths is the self-adhesive backing, making installation straightforward even for those who prefer DIY projects. Additionally, it features a unique indicator that shows if the mat is installed correctly, which can be really helpful for first-time users.
The product covers 50 square feet, providing ample material for various areas in a car. Its relatively lightweight design (17 pounds total) ensures that it won’t weigh down your vehicle significantly while still delivering good sound insulation.
While the 50 mil thickness is effective for sound dampening, some users might find it insufficient for extreme noise conditions. Additionally, the weight, while manageable, may still be a concern for those looking to minimize vehicle weight overall. Furthermore, users may need to prepare their vehicle surfaces properly to ensure the adhesive sticks well, which can add to the installation time.
KILMAT provides a user-friendly and effective solution for sound deadening, ideal for car enthusiasts and everyday drivers who want to enjoy a quieter ride. Just be mindful of the installation requirements and the depth of sound insulation you need for your specific situation.

Most important from
26358 reviews
The KILMAT 80 mil Car Sound Deadening Mat is a solid choice for those looking to reduce noise in their vehicles. At 80 mil thick, this product offers significant insulation capabilities, making it effective for sound dampening. Its butyl and foil composition ensures a strong adhesive grip, allowing for easy DIY installation. The user-friendly design includes sheets that are manageable in size, simplifying the cutting and application process. A unique feature is the installation indicator on the foil, which helps you know if the material is applied correctly, ensuring optimal performance.
While KILMAT boasts many advantages, there are a few considerations to keep in mind. Weighing around 0.5 pounds per square foot, it may add noticeable weight to your vehicle if covering large areas. Additionally, although the product is designed for ease of use, those unfamiliar with DIY projects might still find installation a bit challenging without prior experience. The material is also not designed for extreme heat resistance, so it’s best used in areas not directly exposed to high temperatures.
Given its specifications and features, KILMAT is particularly suited for car owners looking to enhance their driving experience by reducing unwanted noise without too much hassle.

Dynamat Xtreme Sound Deadening Car Insulation Bulk Pack 10455 – Noise Dampening for Floor, Doors, Panels, Hood or Trunk – Easy Self Adhesive Install – Made in USA – 9 Sheets 18”x32”, 36 sq ft total
Most important from
2114 reviews
The Dynamat Xtreme Sound Deadening Bulk Pack is a popular choice for reducing unwanted noise, vibrations, and heat inside cars. Made from a sticky butyl rubber material, it’s thin at 1.7 millimeters but flexible enough to fit on floors, doors, panels, hoods, or trunks. With 36 square feet of coverage spread over nine sheets, this pack is a good fit for a 2-door sedan, providing substantial sound insulation without adding much bulk.
Installation is straightforward thanks to its peel-and-stick design, so you don’t need special tools or professional help. It’s also heat resistant, helping keep your car cooler and protecting against engine or road heat. On the downside, the total weight is about 15 pounds, which is a bit heavy to handle during installation and adds extra weight to your vehicle. Also, while the 36 sq ft coverage suits smaller cars well, it might fall short for larger vehicles or those wanting to cover more areas extensively.
This product serves as a trusted, easy-to-apply solution that significantly reduces road noise and vibrations, contributing to quieter and more comfortable rides.
