Firewall™ Thermal Insulation Kit

Second Skin's Firewall™ Kits will take any vehicle firewall from 0 to 100. Damplifier Pro™ mats are 2mm of American made butyl rubber (NO ASPHALT!) and a thick, annealed foil. The sound deadening mats will deaden your firewall's vibrations while also adding some much needed thermal insulation. Your second layer is Mega Block™, our top of the line thermal insulator and radiant heat barrier. By combining Damplifier Pro™ with an engine heat shield, you'll be shielded from engine heat while also creating a soundproof firewall to reduce engine noise in your cabin. We also have a thermal ceramic coating that can be brushed, rolled, or sprayed on!


Most firewalls are irregular surfaces, so you'll need to cut both your Damplifier Pro™ and your Mega Block™ to fit for the best results. Damplifier Pro™ should be applied to as close to 100% of the metal firewall as possible to get the full benefits of Damplifier Pro™'s thermal insulation. Cut the Mega Block™ to fit with scissors and then tape the seams with foil insulation tape. Both Damplifier Pro™ and Mega Block™ include a peel & stick adhesive for easy application. Make sure you have 2" of clearance between any insulation materials and your heat source.
