Product Description
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.
- 0.5 inch 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
Product Usage Tips
- Choose between standard Mega Zorbe, which can be applied with our Contact Spray Adhesive and peel & stick Mega Zorbe that includes an adhesive backing.
- We do not recommend using this product in heat bays or near heat sources. For high heat applications, try Mega Block.
- To continue enhancing sound and thermal insulation properties, stack Mega Zorbe on top of itself to 1" or even 2" of total thickness.
- The R-Value of open cell foam makes Mega Zorbe excellent for additional insulation in the doors and above the headliner.
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.
