Ummickl Aluminized Heat Shield Mat 12 x 48 in — Adhesive-Backed Peel-and-Stick Thermal Barrier, High-Temp Reflective

Ummickl 12" x 48" aluminized adhesive heat shield mat is a peel-and-stick thermal barrier that reflects radiant heat and protects surfaces from high temperatures.

This flexible, adhesive-backed blanket combines an aluminized reflective face with woven fiberglass insulation to create a high-temperature barrier for automotive, household and appliance applications. The mat is designed to be easy to install on curved or flat surfaces—doors, hoods, firewalls, refrigerator exteriors, cabinets near ovens, exhausts and other areas where radiated heat can cause damage. Its aluminized surface reduces radiant heat transfer while the fiberglass core helps maintain structural integrity at elevated temperatures.

How does this heat shield protect vehicle parts and interiors?

The aluminized layer reflects a large portion of radiant heat away from sensitive components, while the fiberglass mat resists heat conduction and maintains form at high temperatures. It is useful behind exhaust systems, on firewalls and beneath hoods to reduce heat transfer to plastics, wiring and paint.

• Reflects up to 97% of radiant heat to lower surface heating.
• Withstands extremely high temperatures due to woven silica fibers.
• Adhesive back allows direct application to curved and flat automotive surfaces.

How easy is it to install and shape around tight spaces?

The mat includes an adhesive composite on the back for peel-and-stick mounting, letting you wrap or lay the material with a clean finish. It’s flexible enough to conform to contours, yet firm enough to hold its shape once applied.

• Peel-off backing for straightforward, tool-minimal installation.
• Flexible aluminized face conforms to curves and seams.
• Trim-to-fit sizing for custom applications and overlays.

What temperature resistance and durability can I expect?

Constructed with an aluminized surface and woven silica (fiberglass) core, the blanket is engineered to handle extremely high radiant temperatures without rapid degradation. While reflective performance addresses radiant heat, the fiberglass core provides dimensional stability and resistance to thermal breakdown.

• Aluminized finish shields against intense radiant heat.
• Woven silica/fiberglass resists high-temperature exposure.
• Durable construction for long-term applications in harsh environments.

What surfaces and projects is this product best suited for?

This adhesive-backed thermal mat is made for both automotive and home use where radiant heat needs to be controlled. Install it behind stoves or ovens, on refrigerator exteriors, near engine bays, along door panels, or as a protective layer under carpeted floors in vehicles.

• Automotive: firewalls, engine bays, exhaust tunnel covers, heat-prone panels.
• Household: cabinet backs near ovens, refrigerator sides, laundry room heat shields.
• DIY and industrial: heat barrier linings, temporary shielding during repairs.

Who is this for: The Ummickl 12" x 48" aluminized adhesive heat shield mat suits car enthusiasts, mechanics, home renovators and DIYers who need a compact, peel-and-stick thermal barrier that’s easy to shape and install. Choose this mat when reflective performance, high-temperature resistance and a tidy adhesive application are priorities for protecting components, finishes and nearby materials from radiant heat.
