Mega Zorbe™ - Hydrophobic Melamine Foam
The last step of any vehicle soundproofing project is absorbing noise that’s already in the cabin. Enter Mega Zorbe™, 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 a hydrophobic foam 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.
