   ResoNix Barrier is a fully formable and moldable noise barrier designed specifically for automotive use, serving as a modern replacement for traditional Mass Loaded Vinyl (MLV) barriers. Unlike typical MLV, this product is much thinner and easier to work with, yet twice as effective due to its higher mass per square foot (2 lbs per sq ft compared to the standard 1 lb per sq ft for MLV). It also features two external layers of closed-cell foam decouplers, enhancing its noise-blocking capabilities and simplifying installation.
   ResoNix Barrier has a Sound Transmission Class (STC) rating of 33 when hanging by itself, making it twice as effective as standard 1 lb per sq ft MLV commonly used in automotive applications. Its higher mass per square foot and integrated decoupler layers contribute to superior noise-blocking performance compared to other products on the market.
    Yes, it is fully formable and moldable, making it suitable for fitting complex shapes and contours within your vehicle. Its thin design and flexible materials allow it to conform to various surfaces, making installation easier compared to rigid or thicker mass loaded vinyl and other noise barrier products.
   ResoNix Barrier is highly effective when used as a block-off plate for inner door skins. Its moldable nature allows it to conform to three-dimensional inner door skins where traditional materials like ABS plates might be difficult to install. The thicker foam version (7mm) is particularly beneficial in this application, providing excellent decoupling and noise reduction.
   Each sheet measures 54 inches by 36 inches, providing 13.5 square feet of coverage. The sheet weighs approximately 19 lbs, with a mass of 2 lbs per square foot.
      As of January 2025, we are only offering the 3mm foam thickness version.
   ResoNix Barrier is designed to be more user-friendly than traditional MLV barriers. Its thin, moldable design makes it easier to work with, potentially making it suitable for DIY installation. However, installation can be complex and time-consuming, depending on your vehicle and the areas you wish to treat. If you’re not comfortable with the installation process or working with automotive interiors, hiring a professional may be advisable.
    To securely attach ResoNix Barrier on vertical surfaces, use mechanical fasteners such as riv-nuts or well-nuts. These provide a secure and stable attachment, preventing the barrier from slipping or sagging over time. Avoid using Velcro or adhesives, as the foam outer layers are too soft to hold effectively. For horizontal surfaces, such as vehicle floors underneath carpets, let gravity do its job.
To install ResoNix Barrier, you will need:
   No, ResoNix Barrier does not feature an adhesive backing layer. It should be secured using riv-nuts or well-nuts, especially on vertical surfaces. The foam outer layers are too soft to use with Velcro or similar fastening methods. For vehicle floors underneath carpets, let gravity do its job.
   It’s best to remove the existing vapor barrier before installing ResoNix Barrier. Installing over the old vapor barrier can trap moisture between layers and may reduce the effectiveness of the soundproofing. Removing the old barrier allows it to function optimally as both a noise barrier and a new vapor barrier.
    No, it is not recommended to use Velcro to attach ResoNix Barrier. The foam outer layers are too soft to provide a secure hold with Velcro. Instead, use riv-nuts or well-nuts for a reliable and durable installation.
When handling and installing ResoNix Barrier, take the following precautions:
   Yes, ResoNix Barrier carries a California Proposition 65 warning. This product contains chemicals, including lead, known to the State of California to cause cancer, birth defects, or other reproductive harm. Users should handle the product with care and follow all safety guidelines.
   ResoNix Barrier is primarily designed for automotive use but is also suitable for industrial applications, especially where tight tolerances and complex curves are involved. While it can be used in marine applications, it’s less common, and another product like ResoNix Guardian might be more appropriate for marine environments.
    Noise barriers, especially in automotive applications, are much trickier than other types of sound treatment products. For significant noise reduction, it’s recommended to cover as close to 100% of the vehicle’s interior surfaces as possible. Treating only certain areas, like the doors, may result in minimal improvements. Focusing on the entire floor, wheel wells, and using sound-absorbing materials on the sides can lead to more substantial reductions in road noise.
    Before purchasing and starting your installation, I would highly recommend reading our ResoNix Sound Deadening Materials Reference Information & Guide article to understand how and why they work so you can make sure that you install ResoNix Barrier in an effective manner.
   Yes, using ResoNix Barrier in conjunction with other ResoNix products like Fiber Mat and CLD Squares can enhance overall noise reduction. While ResoNix Barrier acts as a mass barrier to block noise, ResoNix Fiber Mat absorbs sound that may bypass the barrier. Combining these products provides a comprehensive approach to soundproofing your vehicle.
   A decoupler between the noise barrier and the vehicle panel is important for effective decoupling. This decoupling prevents vibrations from transferring between surfaces, enhancing the barrier’s ability to block noise. ResoNix Barrier includes integrated closed cell foam layers to facilitate this decoupling.
   Having an air gap between the noise barrier and the vehicle panel is important because it enhances the barrier’s ability to block sound. The air gap acts like a buffer or cushion that prevents sound vibrations from passing directly from the vehicle’s metal panels to the noise barrier. This separation reduces the transfer of noise and vibrations, making the soundproofing more effective and keeping your vehicle interior quieter.

   The uncompressed thickness of ResoNix Barrier is approximately 14mm (0.55 inches) for the version with the 7mm foam layers. The version with the 3mm foam is approximately 7.5mm (0.3 inches). When compressed, the thickness on the 7mm foam can reduce to about 1.06mm (approximately 1/24 inch) and can reduce to 0.5mm (1/50 inch). The lead sheet itself is 1/32 inch (0.8mm) thick.
   The mass of ResoNix Barrier is a key factor in its noise-blocking capabilities. Sound transmission loss increases with the mass of the barrier; heavier materials are more effective at blocking sound. ResoNix Barrier weighs 2 lbs per square foot, which is double the mass of standard MLV barriers, resulting in superior sound-blocking performance.
   Yes, ResoNix Barrier is proudly made in the United States of America. As a matter of fact, it is assembled right here in our warehouse.
After installing ResoNix Barrier, follow these clean-up steps:
   Installing ResoNix Barrier on the headliner is generally not recommended due to its weight. The added mass could be too heavy for the headliner structure to support safely. For an easy installation in the headliner area, consider using a lighter sound-absorbing material like ResoNix Fiber Mat. The only time I would recommend Barrier on the roof is if you can mechanically secure it to the roof supports. This will prove to be difficult, but as they say, hard work pays off. You should still supplement the installation of ResoNix Barrier with Fiber Mat in the headliner.
   The thicker foam version (7mm) provides better decoupling between the barrier layer and the vehicle panels, and a thicker air gap, enhancing the noise reduction capabilities. It is especially beneficial when space allows and is ideal for applications like blocking off access holes on inner door skins. The increased foam thickness improves the overall effectiveness of the barrier by reducing vibration transmission.
To summarize, it allows ResoNix Barrier to block airborne noise more efficiently.
ResoNix Barrier offers several advantages over other soundproofing materials:
   Currently, there is no official installation manual available for ResoNix Barrier. However, installation guidance and best practices can be found on the product page and through customer support.
   Yes, by reducing external noise and vibrations within the vehicle, ResoNix Barrier can enhance the listening environment for your car’s audio system. A quieter cabin allows for clearer sound reproduction and can improve overall audio quality.
