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 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.



  • 1/2" thick hydrophobic melamine foam
  • Lightweight, flexible, water resistant, and Class A fire rated
  • Aerospace grade sound absorber and thermal insulator (R-value per inch: 4.16)
  • Each sheet is 24” x 24” (4 Sq Ft) and about 1/10 of a pound
  • Thermal range: -40°F to 350°F (-350°F to 350°F without adhesive)
  • Choose whether to add a peel & stick backing or sheets with no adhesive
  • Meets all aerospace, transportation, and architectural standards for fire, smoke, toxicity, and water resistance
  • Made in Germany and treated in the USA

Installation Instructions

  • Recommended Installation: First, remove your door panels and/or vehicle headliner (watch an in-depth guide on Mega Zorbe™ installation here). 
  • The best way to handle Mega Zorbe™ is to first cut it down to the size of the install location, making sure to leave room for wiring and other electrical components.
  • Mega Zorbe™ cuts easily: a simple pair of scissors will do the job! After you make your cuts, simply peel & stick!
  • For thicker foam options, consider our Mega Zorbe™ Pro, which comes in 1" or 2". 
  • You can also stack Mega Zorbe™ on top of itself for more thermal and sound insulation to 3" or even 4" of total thickness using a spray adhesive, like our Contact Spray Adhesive or P329 Permanent Spray Adhesive.
  • The high R-value of open cell foam makes Mega Zorbe excellent for additional insulation in the doors and above the headliner.
  • DO NOT use MegaZorbe™ on the floor of your vehicle because the open cell foam will decay over time if weight is constantly on it.
  • We do not recommend using this product in heat bays or near heat sources. For high heat applications, try Mega Block.
