Nova Zhang
Dynamat is a brand of automotive soundproofing and heat insulation products. Their products are designed to reduce unwanted noise and heat in vehicles, homes, and boats. Dynamat's sound control materials are thin, flexible, and easy to cut and mold. They work by stopping noise-causing resonance and vibration through a process called damping, which converts noise into silent low-grade thermal energy. While Dynamat products are popular and trusted by many, there are also cheaper alternative products on the market that offer similar benefits.

Dynamat Xtreme
In addition to automobiles, Dynamat Xtreme can be used in the home and for architectural applications. It is effective at reducing noise and vibrations from household appliances such as dishwashers, air conditioners, ductwork, and piping. Dynamat Xtreme can also be combined with other Dynamat products, such as Dynaliner, DynaPad, or DynaDeck, to further enhance heat insulation and reduce low-frequency hums from large engines and exhaust systems.

Dynamat Dynaliner
Dynaliner is often used in conjunction with Dynamat Xtreme, a super-thin sound control material designed to dampen noise-causing vibrations. When used together, the two products nearly double the total thermal resistance ability and improve noise control. Dynaliner can be used on top of Dynamat Xtreme to insulate the roof, firewall, floor, quarter panels, doors, and even under the hood.
The combination of Dynamat Xtreme and Dynaliner can be used to solve both types of sound problems: vibrational noise and air-borne noise. Dynamat Xtreme is applied first, followed by Dynaliner, with the thickest Dynaliner being used that the space will allow. The process of converting noise into silent energy is called "damping".

Dynamat in the trunk
Dynamat is a thin, flexible, easy-to-cut-and-mould sheet that stops noise-causing resonance and vibration. It uses visco-elastic qualities to promote vibro-acoustic energy conversion, essentially converting noise into silent energy. Dynamat's sound control material is designed to dampen noise-causing vibrations and is proven to remove resonance in sheet metal and carbon fibre panels. Dynamat products can be used to reduce unwanted noise and vibration in vehicles, boats, generators, dishwashers, air conditioners, ductwork and piping.
Dynamat Xtreme is a super-thin sound control material that can be applied to the trunk of a vehicle to reduce vibration and deliver more bass, louder bass, and higher-quality low-frequency bass. The Dynamat Xtreme Trunk Kit helps to stop the trunk from vibrating and letting in road noise, giving you a quiet car that feels solid. Dynamat claims that their product is the easiest-to-apply, thinnest, and lightest material for adding sound pressure reinforcement to your car's body.
The Dynamat Xtreme Trunk Kit comes in pre-cut pieces that are easy to install with a simple peel-and-stick application. The kit contains 20 square feet of Dynamat Xtreme in five 18"x32" pieces, enough to cover a standard car trunk. The kit helps to dampen vibrations that would otherwise interfere with your subwoofer's punch and clarity.
In addition to the Dynamat Xtreme Trunk Kit, Dynamat also offers a range of other products that can be used in the trunk to reduce noise and vibration. These include the Dynamat ProX, a thicker and heavier version of Dynamat Xtreme, as well as Dynaliner, DynaPad, and DynaDeck, which can be added to fight heat and low-frequency hums from large engines and exhaust systems.

Dynamat on doors
Dynamat is a thin, flexible, and easy-to-cut and mould sheet that stops noise-causing resonance and vibration. It uses visco-elastic qualities that promote vibro-acoustic energy conversion, which means that noise becomes silent energy. Dynamat Xtreme is a super-thin sound control material designed to dampen noise-causing vibrations. It is used by car lovers and professionals alike to make their cars quieter and cooler.
The Dynamat Xtreme Door Kit contains enough material to cover two standard car doors. The Dynamat Xtreme comes in four 12"x36" pieces that are easy to apply with a simple peel-and-stick application. The proprietary blend of butyl rubber adheres to the surface and stays in place.
Dynamatting the front and rear doors can make a significant difference in the sound and feel of a car. The doors will "feel" more premium when closing them, and the sound difference in road noise is amazing. The buzzing and vibrating of the plastic with the factory speakers are eliminated, even in the front doors with more powerful speakers.
It is recommended to use a roller kit that provides a medium and small roller for hard-to-reach areas when applying Dynamat to doors. It is also important to note that removing the door panels may be necessary for proper installation. Overall, Dynamatting the doors can greatly improve the sound and comfort of a vehicle's interior.

Frequently asked questions
Dynamat products are designed to reduce unwanted noise and vibration. They are thin, flexible sheets that stop noise-causing resonance and vibration by using visco-elastic qualities that promote vibro-acoustic energy conversion. Dynamat can be used to reduce noise and vibration in vehicles, homes, and marine applications.
To make any noticeable difference in noise reduction, a minimum of 30% coverage will be needed. Full coverage of any given area will always give the best performance. For example, treating all the doors (and the rear hatch for SUVs) can reduce noise by 3-6 dB, which is a 25-30% reduction in noise.
Dynamatting your doors creates a solid, acoustical speaker enclosure that reinforces your speakers and enhances mid-bass performance and power handling. Applying Dynamat in the trunk of your vehicle reduces vibration and delivers louder and higher-quality low-frequency bass.
