Keep your cool in the heat with our HP Heatshield Mat. When used in applications when there is 1” of airspace and air flow, this heat shield cloth is capable of reflecting 90% of radiant heat. Face the aluminized side toward the source of radiant heat to shield heat away. This product withstands 1100°F of radiant heat (requires minimum of 1” of airspace) and up to 450°F of direct heat. This is perfect for using underneath your floor pan to shield heat from your DPF, muffler, catalytic converter, and exhaust system on your heavy duty vehicle, or it can be used on your firewall to shield motor heat. It can also be used as a cold air intake heat shield, stick this onto your metal or plastic air box to stop heat from heating up your intake. The HP Heatshield Mat is available with a high temperature peel and stick adhesive. Bulk heat shield cloth rolls available.

HP Heatshield Mat Installation tips:

  • Be sure to use a 1" air-gap between HP Heatshield Mat and heat source for best results
  • HP Heatshield Mat is intended to be applied on the cold side of panel or component, i.e. it is not intended to direct contact with heat source

Required tools:

  • Heavy duty scissors or utility knife 
  • Carburetor cleaner or other degreaser
  • Pre-paint cleaner or other non residue cleaner
  • 3M Super Trim adhesive or other spray adhesive (Part #720305 & 720505 only)
  • Poster board, heavy paper - optional

PRO TIP - Use poster board or butcher paper to make a template. For surfaces with severe bends, it may be necessary to cut relief lines or wedges to get product to conform. Transfer template to HP Heatshield Mat and cut.

  1. Panel or component surface temperature should be at least 65°F, sticking onto anything colder may not allow adhesive to set up properly.
  2. Degrease and clean surface of any residual chemicals, using carburetor spray or other cleaner/degreaser.
  3. We strongly recommend rubbing the surface with a pre-paint cleaner or isopropyl alcohol (or other non-residue cleaner) after cleaning and degreasing. For part # 720305 & 720505, without adhesive, skip to Step 7
  4. Carefully peel the adhesive backing off theHP Heatshield Mat. Start peeling from one corner.
  5. Lay the HP Heatshield Mat, start on one edge of panel or component and work out slowly to ensure no “bubbles” occur. Air bubbles will cause the material to not stick and fall off.
  6. Press the HP Heatshield Mat firmly onto the panel/component, hold while pressing down for 2 minutes. Skip to Step 9
  7. Non adhesive product only - Use 3M Super Trim or Super 77 Adhesive. After HP Heatshield Mat has been cut, spray back of cloth and panel or component you are applying HP Heatshield Mat to.
  8. Allow adhesive to get tacky and apply cloth, start on one edge of panel or component and work out slowly to ensure no “bubbles” occur. Air bubbles will cause the material to not stick and fall off. Press firmly for 2 minutes.
  9. Optional - If using edge tape like Cool Foil Tape, clean the edge of HP Heatshield Mat with the pre-paint cleaner or isopropyl alcohol.
  10. Optional - Pre-fit and trim tape to fit the HP Heatshield Mat.
  11. Optional - It is important to do one edge/seam at a time with the edge tape.
  12. Optional - Peel adhesive backing off tape, press and firmly hold in place for 2 minutes.
