Dynamat is a thin, flexible, easy to cut and mold sheet that actually stops noise causing resonance and vibration, by using visco-elastic qualities that promote vibro-acoustic energy conversion. In short, that means noise becomes silent energy.
You can apply Dynamat in patches (25-50% area coverage) to keep a specific panel from resonating or you can apply it over an entire area (such as the floor, doors, or boot) to create a sound barrier and vibrational damper.
Even a small amount of Dynamat can cause a profound noise reduction. For example, applying Dynamat to the doors of your vehicle can reduce road noise from 3-6dB!. Complete coverage of an average vehicle can reduce road noise 9, 12 even as much as 18dB.
As a car operates, it generates noise. This noise is caused by the transference of energy (vibration) from the internal components and from the road to the chassis of the vehicle. The chassis (doors, floors, roof etc.) transforms this vibration into audible noise. Dynamat transforms the energy (vibration) into silent energy.
Known as a ‘constrain layer damping material’ Dynamat Xtreme is made up of an extruded self-adhesive black butyl rubber with an aluminium foil constraining layer which allows the butyl to perform at maximum efficiency. The product has an overall thickness of 1.7mm and has a peel and stick application.
Dynamat Xtreme deadens uses a process called ‘damping’ – which in simple terms – is the process of restraining vibration (noise) by dissipating or using up the energy causing those vibrations. Dynamat converts the movement of the vibration and turns it into silent low-grade thermal energy. No more noise = problem solved at source.
• The ‘Dynamat difference’ comes from the patented chemical formula within the Butyl rubber (think KFC secret blend of herbs and spices), this is known as our VECTOR™ chemistry.
• The process that occurs within Dynamat Xtreme to silence the kinetic energy (vibration) is called ‘Vibro-acoustic energy conversion’
• Dynamat have used the same chemical and aluminium suppliers since 1998 because of our commitment to product quality and consistency – we know exactly what is in our products – do the competition?
• Dynamat is proudly made in the USA and everything involved – even down to the card packaging is sourced within a 200 mile radius of the HQ in Hamilton, Ohio USA.
• Dynamat Xtreme doesn’t contain bitumen and therefore carries no odour and does not have a ‘shelf life’ or degrade over time.
• Thicker is not better – it is a misconception fuelled by copymat producers – if they’re product damping performance matched ours then their product would be made thinner.
We have independent testing on our products and those of other producers. These tests are performed to obtain what is known as an ‘acoustic loss factor’ – the theoretical maximum this value can be is 1 (no vibration). Dynamat Xtreme comes out on top consistently @ +68°F (+20°C) – typical temperature of real-life environment. Dynamat Xtreme has an acoustic loss factor is 0.42 at 200HZ and is 2.2KG/ Msq. This proves that Dynamat Xtreme is the most efficient constrain layer damping material on the market.
Dynamat meets the US federal motor vehicle safety standard (FMVSS) 302. The UK equivalent of this is ISO3795.
Further detail: This test assesses the horizontal burn rate of materials used in an automotive vehicle environment. Does your copymat product carry this rating? If not how can you be sure the product is safe for purpose? Roofing materials from DIY stores are not likely to meet this certification as they are produced with the intention of being used on a roof. (FYI – only certain STP products meet the Russian equivalent of this standard GOST25076)
The Dynamat range of products are used to control noise and heat in all manner of applications. There are different products within the range that solve these issues in the most effective way based on the source and application. Dynamat Xtreme is used to eliminate structure-born noise or vibration and Dynaliner is used as a thermal insulator, although when used together they perform better as a pair.
Dynamic Control provides solutions for most vibration, noise and heat isolation problems. See the products section for more information on specific solutions for each part of your vehicle.
We recommend applying Dynamat to any surface you can easily reach. In general, we recommend treating your vehicle in the following order: Doors, Boot, Parcel Shelf, Floors, Roof, Bonnet, Quarter Panels.
Heat coming from a hot exhaust or headers is a common problem. Fortunately, Dynamic Control has a solution. First apply Dynamat Xtreme to the floor and firewall, then install Dynaliner, both underneath the floor's carpet. This process is outlined in Dynamat Floor Applications.
Installing Dynamat requires only a few tools: razor knife or scissors, roller tool, rags and a solvent- based cleaner (rubbing alcohol also works). You also need basic hand tools for the disassembly and reassembly of your vehicle. Consult your owner's manual or vehicle's shop manual for instructions. Review the Car Audio Installation Instructions before starting.
