Lava Shield Mat is a very rugged heat shield barrier! Due to basalt’s (mineral from volcanic rock) natural chemical and acid resistant properties, Lava Shield is excellent for use in harsh environments, like underneath your truck or heavy duty equipment. This heat shield barrier cloth, can be used with less than 1” of airspace, 3/8” minimum is recommended. It is also better to use Lava Shield when there are instances of little air flow, making it a superior insulator to aluminum and gold barrier fabrics in these occurrences. Bulk rolls of basalt heat shield cloth are available. Our Lava Mat Heat Shield withstands 1200°F direct continuous and 2000°F intermittent.

 Required tools:

  • Patience 
  • Carburetor cleaner or other degreaser
  • Pre-paint cleaner, isoproyl alchohol or other non residue cleaner     
  • Heavy duty scissors or utility knife
  • Optional - poster board or heavy paper

PRO TIP #1 - 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 Lava Shield and cut.

PRO TIP #2 - Provided by Kevin Byrd of “Two Guys Garage” fame, use super glue on the cut edges to give Lava Shield a fray free and custom edge. You can also use clear high-temperature engine paint on edges if fraying does occur.

PRO TIP #3 - Lava Shield may have wrinkles in it. Wrinkles can be removed during the installation process. You can also lay Lava Shield flat, and let it rest overnight with a heavy flat object on top of it to remove wrinkles before installation.


  1. Panel or component surface temperature should be at least 65°F when applying, 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.
  4. Carefully peel the adhesive backing off the Lava Shield. Start peeling from one corner.
  5. Lay the Lava Shield, 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 Lava Shield firmly onto the panel/component. Hold while pressing down for 2 minutes.

Q. Why don't you recommend using Lava Shield on rough, unfinished fiberglass or carbon?

A. Self adhesive backings cannot fill in the surface irregularities that occur on unfinished glass or carbon. For these applications, it is better to use a spray on adhesive.
