Absorbing noise that’s already in the cabin is the last step of any vehicle soundproofing project. Mega Zorbe is an aerospace grade, lightweight melamine foam sheet with excellent physical properties, making it ideal for both sound and thermal insulation. We’ve enhanced our melamine foam through a proprietary treatment to make it hydrophobic and safe for use in vehicles. Our patented process penetrates the entire material to ensure long-lasting and consistent waterproofing. Because it’s an open cell foam, Mega Zorbe is perfect for absorbing those medium and high frequency noises in your vehicle.
Product Usage Tips
Mega Zorbe is commonly used in a variety of industries. Use cases range from energy companies to HVAC ducts to wall insulation for aircraft and other commercial transportation. Great for inside of a bitcoin or crypto mining rig for noise reduction. Call us if you have questions about your specific need.
