Mega Block - Hydrophobic Foam + Heat Shield

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 automotive heat 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 any vehicle needing heat control including engine compartment insulation for your boat.

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.
• Used in non-automotive locations as well, like generator boxes or a soundproof server rack

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