ResoNix Sound Solutions - Guardian: Sound Absorber & Barrier Product Spotlight

resonixsoundso...
ResoNix Guardian is a multi-layered product that is comprised of a Hydrophobic Acoustical Polyester Cloth Facing, a 1″ thick Hydrophobic Melamine foam layer, a 1/8″ thick 1lb Mass Loaded Vinyl Layer, another 1/4″ thick Hydrophobic Melamine foam layer, and a peel-and-stick acrylic-based adhesive backing. ResoNix Guardian has three main purposes. To absorb sound, block sound, and insulate from heat. The most common use for this product will be inside of doors in car audio applications for rear wave absorption and diffusion of door-mounted midbass drivers, on the underside of vehicle roofs to block broadband noise, absorb wind noise, and insulate from heat, as well as improve bass response in car audio systems. This would also be the easiest and quickest way to treat a camper van for external noise and heat.
Each and every layer of ResoNix Guardian serves its own individual purpose, while also working together towards the common goals of better performance out of your sound system, lowered noise floor inside of the cabin, and less heat transfer to the inside of the vehicle.
Hydrophobic Melamine Foam
The two layers of Hydrophobic Melamine foam are arguably the most important. Not only is it an excellent acoustic absorber, but is an aerospace-grade thermal insulator. This product is quite literally used on the tips of Space-X rockets for thermal insulation. Anyways, for car audio applications, Guardian will be used inside of door cavities, stuck to the outer door skin, (AFTER a CLD is applied, preferably ResoNix CLD Squares). In this scenario, the Hydrophobic Melamine is being used to absorb acoustic energy from the rear wave of the door-mounted midbass driver. This will reduce the amount of energy that reaches the outer door skin, which creates the most resonance in the door of a vehicle. This will also in turn reduce the amount of acoustic energy that can be reflected back and transferred into the inner door skin which will cause further resonance but also rattles.
Being used in a headliner/roof will offer some other benefits. With our ResoNix Fiber Mat, you only get acoustic absorption and thermal insulation. With ResoNix Guardian you also get the added benefit of being able to finally install a noise barrier (more on this below) into your roof while still having the benefits of a great acoustic absorber and thermal insulator. As of writing this (January 26th, 2023), we haven’t been able to compare ResoNix Guardian to ResoNix FIber Mat 25 & 45 in a roof installation. The Hydrophobic Melamine will also come in handy for those building out vans for camping and travel purposes. Not only will it drastically lower the noise floor in the vehicle, but it will also help keep heat out in the hot summer months, and help trap heat in during the winter, making your home on wheels more comfortable and efficient.
Now, melamine being an open-cell foam would normally be problematic for automotive installations. But for ResoNix Guardian, a proprietary process is used to treat our Melamine to make it fully hydrophobic, inside and out. This isn’t some cheap spray you can buy at Home Depot that will wear off in 4 months. We can guarantee that this product will never absorb water for the life of your vehicle. Due to this, it can be used without worry in door cavities, on the underside of hoods, and even on underbody pans and other places on the outside of the vehicle. No matter what you throw at it, ResoNix Guardian can handle it.

What Does This Combination Of Materials Leave Us With?
Since the materials that ResoNix Guardian is comprised of are fully hydrophobic, each panel can be cut into custom shapes and sizes to fit your individual application needs. The peel-and-stick adhesive makes for an extremely easy installation and finally allows for the installation of a noise barrier inside of door cavities and roofs without needing to figure out a complex mechanical mounting solution, or sacrificing full coverage which finally allows you to have an effective noise barrier, acoustic absorber, and thermal insulator installed anywhere in your vehicle, inside and out. This truly is our most versatile product to date. If you have any questions on where and how this will benefit your installation, feel free to give us a call or send us an email anytime.

Nick, what’s the R value of the Guardian? I’m thinking about using it to insulate and sound treat the rear compartment of the time machine.

[@ResoNixSoundSolutions]

Hey, the R-Value of the Hydrophobic Melamine portion is 4.15 per inch, and there is 1.25 inches total. We have yet to do testing to get the R-Value of the total composite product that is Guardian.

[@josephcullen2512]

Does the vinyl contain phthalates or is it phthalate free? I've been hoping for some company to make phthalate free mass loaded vinyl with plasticizers that are of less concern than phthalates. It would be a good feature for marketing too

Thanks!

Will this work for diesel engines ?

@@abc-ed1nr hard to say. Can you be a bit more specific?
