Thermo-Tec Heat and Sound Suppressor 60" x 36" panel — 70 mil foil-faced thermal & acoustic barrier

Thermo-Tec 14620 60" x 36" Heat and Sound Suppressor is a 70-mil, foil-faced thermal and acoustic barrier designed to cut radiant heat and reduce engine and road noise in vehicles.

Built for automotive and light industrial applications, the Thermo-Tec 14620 combines a reflective foil surface with a polyethylene film and a high-temperature adhesive backing. The 60" x 36" panel is easy to trim and fit, making it suitable for firewalls, floorboards, doors, and other areas where heat protection and noise mitigation are needed. Its construction focuses on reducing radiant heat transfer while dampening a range of mechanical noises to improve occupant comfort and concentration.

How does this suppressor reduce heat in confined spaces?

The foil-facing reflects radiant heat away from surfaces while the polyethylene film adds an insulating layer to slow conductive transfer. Together they form a barrier that protects substrates from high temperatures in engine bays and near exhaust components.

• Foil surface reflects radiant heat from engines and exhausts
• Polyethylene film provides additional insulating separation
• High-temperature adhesive bonds to metal and composite panels
• 70 mil thickness for durable thermal performance

Will it help reduce engine and road noise inside a vehicle?

Yes—the panel adds mass and damping that reduces certain engine tones and road vibration before they reach the passenger cabin. It won't eliminate all noise frequencies but noticeably lowers common HVAC, drivetrain and road sound levels for better comfort.

• Mass and surface damping reduce structure-borne noise transmission
• Effective against mid-to-low frequency engine and road noise
• Can be applied to floors, doors, and firewall areas where noise enters
• Improves driver focus and passenger comfort without major vehicle modification

How do I install and trim the 60" x 36" panel?

Installation is straightforward: measure the target area, cut the panel to shape with a utility knife or shears, peel the liner, and press the adhesive side firmly onto a clean surface. The high-temperature adhesive holds well to metal and many composites; use firm pressure and allow time for the bond to set.

• Trim with scissors, shears, or a sharp utility blade
• Surface preparation: clean, dry, and degrease before applying
• Peel liner, align panel, press firmly to engage adhesive
• Best for flat or gently contoured surfaces; additional mechanical fasteners optional

What durability and safety features does Thermo-Tec 14620 offer?

The product's 70-mil thickness and foil layer provide robust protection against radiant heat while resisting punctures and wear in automotive environments. The high-temperature adhesive and materials are selected to tolerate elevated under-hood and body temperatures encountered in normal vehicle use.

• 70 mil thickness for mechanical durability
• Foil surface resists radiant heat and abrasion
• High-temperature adhesive sustains bond under heat cycling
• Trim-to-fit format reduces waste and simplifies installation

Who this product is for: Automotive technicians, restoration specialists, and DIY vehicle owners who need a compact, easy-to-fit solution for blocking radiant heat and reducing cabin noise. It’s suited for people upgrading firewalls, soundproofing floorboards, sealing door cavities, or adding localized thermal protection near hot components, without extensive fabrication or permanent structural changes.
