Mega'Block Peel & Stick Hydrophobic Melamine 1/2" Foam - 1 Strip (24"x12"= 2 sqft)

Calculated at checkout

Product Description

Mega’Block Hydrophobic Melamine Heat Shield Strip (Peel & Stick) 24" x 12" x 1/2"= 2 sq ft  

 an aluminum foil-faced fiberglass fabric composite bonded on top of Mega’Zorbe hydrophobic melamine foam. Specifically designed to reflect radiant heat while offering excellent sound absorbing attributes utilizing an easy peel and stick application. Mega’Block is an enhanced version of melamine foam with exceptional water-resistance properties maintaining all other key attributes for sound deadening. The open cell surface allows sound waves to penetrate the foam and not reflect as an echo. It is recommended for both acoustical and thermal insulation in aircraft, aerospace, marine, automotive, and architectural applications.

Typical uses include: engine side of firewall or hood, exhaust tunnel, transmission tunnel, under seat or above engine on ATV/jet ski/snowmobile. (Product should be installed at-least 2” from the heat source. Foil tape Is recommended on the edges to protect the foam)

Mega’Zorbe is designed and manufactured in Germany with the proprietary hydrophobic process being completed in the USA. Mega'Zorbe is eco-friendly, produced without using halogenated hydrocarbons and/or toxic heavy metal flame retardants. (*Nitrogen is used to create flame resistance).The light weight characteristic reduces weight contributing to energy savings thus reducing emissions. 

  • Easy Peel and Stick application with high heat adhesive 
  • Thermal rated -40°F to 1,000°F 
  • Highly polished foil reflects 98% of radiant energy
  • Resistant to most organic solvents
  • Aerospace grade product
  • Lightweight and flexible
