![]() There are many ways that you can use mass-loaded vinyl, both around the house or in a commercial or even industrial setting. It feels rubber-like to the touch and is widely used in both residential and commercial home improvement projects alike.Īlthough it is dense, the MLV is highly flexible which allows it to be used in many applications, for example, car hood soundproofing or soundproofing a drum room.Ĭompared to lead, it is nontoxic, making it a safe and useful material to use for all kinds of projects.Īnd finally, mass-loaded vinyl can add a great STC value to any surface due to its sheer mass. It is made to be very thin and with high density, and its primary purpose is to control and stop sound waves from exiting a surface. I found a very noticeable difference when I made a "sheet" of MLV (Mass loaded vinyl) that I put between my rear inner door skins and door panels.A mass-loaded vinyl is a specially created material that aids in soundproofing. They also don't do much, so don't spend much money on it either. Besides, the road noise gets quieter as the stereo volume gets louder.Īlso, roofing products and the like from Home Depot/Lowes are NOT good CLD's (or sound deadeners) because of their construction. My other daily driver is a lifted Wrangler so this Yaris is very quiet comparatively. There is a lot more, but this is a good start. The result will be much better, cost less and take a lot less work. Using a separate barrier to block sound is the right way to deal with the problem. This is yet another case of needing to use the right tool for the job. The doors close with a satisfying "thunk" and the car sounds completely dead when you tap on its panels, but most of us have been disappointed to take our masterpiece out for a ride, only to discover that traffic, road, engine and exhaust noise are only slightly diminished. Many of us have tried following the old way of sound deadening a car - piling on layer after layer of vibration damper. Controlling panel resonance is an essential step to prevent transmission of noise, but you need to block noise at the point of entry to achieve the kind of quiet ride we all want. Once you've applied CLD Tiles, turn your attention to blocking noise. When trim panels buzz or rattle, lining them with CCF will isolate them from whatever they are rattling against. It also creates a more complex path for the sound to travel through, further increasing the effectiveness of the barrier. If the substrate has any residual resonance after treating it with CLD Tiles, using CCF as a cushion will stop the resonance from exciting the barrier material. For a barrier to work well, it should be floated above the substrate to which it is attached. When you want to block noise, you need a massive barrier like Mass Loaded Vinyl Barrier. It will also absorb some very high frequency noise, but let’s not get carried away with that aspect of its use. One layer of 1/4" CCF (Closed Cell Faom) is the ideal decoupler for barriers and trim panels in a motor vehicle. The old adage about using the right tool for the job has never been truer. Controlling resonance is the absolutely critical first step in any sound deadening project, but more isn’t better and trying to use a CLD to block sound is too expensive, too labor intensive and makes it unnecessarily difficult to do future vehicle maintenance. Their only purpose is to control resonance in a vehicle’s panels. ![]() Products like this are vibration dampers. If you’ve been doing any research, you have probably come across the usual arguments: “Buy the good stuff and cover everything” or “Buy the cheap stuff and cover everything with multiple layers. ![]() On metal CLD Tiles to cover 25% of the flat areas "This would take care of the resonances - is just a slightly catchy name for 6” X 10” pieces of constrained layer damper – what we’ve traditionally called sound deadener. I know what I'm going to suggest it's not cheap but here we go any way. I don't know what else there is besides Dynamat to compare it to(I've never dealt with anything else).
