24in x 48in Cool-It Mat

The 24in x 48in Cool-It Mat by THERMO-TEC is a professional-grade heat and sound barrier engineered for serious heat management in engine bays, under-dash installations, and high-temperature equipment enclosures. Designed for automotive technicians, off-road enthusiasts, and industrial users who demand reliable thermal control without adding significant weight or bulk, this barrier addresses the critical need to protect sensitive components and reduce cabin temperatures in performance and modified vehicles.

The 24in x 48in Cool-It Mat features a 0.5-inch thick aluminized foam construction with a reflective silver surface that bounces radiant heat away from critical areas while absorbing and dampening engine noise and vibration. The aluminized facing acts as a radiant barrier, reflecting up to 95% of heat energy, while the foam core provides both thermal insulation and acoustic dampening properties. Weighing just 1.5 lbs, the mat remains lightweight and easy to handle during installation without compromising durability or thermal performance.

This heat barrier is ideal for protecting firewall insulation, wrapping exhaust components, lining transmission tunnels, and shielding electrical harnesses from underhood heat in street cars, race vehicles, and diesel trucks. The 24-inch by 48-inch sheet size provides ample coverage for most engine compartment applications or can be cut and customized to fit specific layouts. Simple adhesive or mechanical fastening methods allow straightforward installation, making it a practical upgrade for both professional shops and experienced DIY builders seeking to improve underhood thermal management and reduce noise transmission into the cabin.
