DESCRIPTION

Keep your cabin cool with Mega Block, specifically designed to be a best-in-class heat shield by combining an aluminum reflective barrier with the excellent thermal insulation attributes of melamine foam. Mega Block is hydrophobic, lightweight, and flexible while reflecting 98% of radiant heat energy. Use it on the engine side of the firewall, as hood insulation, or around the exhaust tunnel in any vehicle.

 

  • 0.5 inch thick hydrophobic melamine foam with an aluminum foil-faced composite bonded on top
  • Lightweight, flexible, and water resistant
  • Reflects 98% of radiant energy
  • Each sheet is 24” x 48” (8 Sq Ft) and weighs about 1/4 of a pound
  • Thermal range: -40 F to 1000 F
  • Resists organic solvents, odor free, and meets smoke, fire, and toxicity standards
  • Aerospace grade product
  • Made in Germany with hydrophobic process completed in the USA

 

Product Usage

  • Always face foil side of the product towards the heat source
  • Easy to apply with our peel & stick adhesive backing. You need to apply enough pressure for your fingers to "feel" the adhesive bonding to the metal surface.
  • Install at least 2” from the heat source. We recommend foil insulation tape on the edges to protect the foam.

Recommended Install Locations

  • Hood - cover entire lid with foil facing the engine
  • Firewall - engine side
  • For rear-engine design layouts, apply to the vehicle's back wall.
