## Products

- [590mil Heat & Sound Deadening Foam Mat (26 sqft)](https://fourub.com/) — ASIN B0DG4Y2BC9. Cut the 15mm mat across a sedan floor pan and press it flat; one 26-sqft sheet covers the full floor without a seam at the center tunnel.
- [Silicone Coated Fiberglass Heat Shield Sleeve](https://fourub.com/) — ASIN B0D14JNQ4Y. Slide the 5/8 inch silicone fiberglass sleeve over a spark plug wire that runs beside the exhaust manifold; it holds 380-393°F continuous and 500°F intermittent for brief manifold proximity.
- [2:1 Heat Shrink Braided Sleeving](https://fourub.com/) — ASIN B0DSKM2QYL. Feed the 1-3/8 inch braided sleeve over a 4-AWG amp cable before you attach the lug, then run an even heat-gun pass across the firewall grommet; the sleeve contracts 2:1 and locks the weave tight to the cable at the…
- [78mil Ceramic Fiber Heat Shield Mat (adhesive)](https://fourub.com/) — ASIN B0FQJ58GY3. Wrap the 78mil strip around a battery heat shield or firewall hot spot with the ceramic side against the radiant source and the adhesive backing on the cool metal behind it.
- [2:1 Flat Heat Shrink Braided Sleeving](https://fourub.com/) — ASIN B0CRB7FGWB. Route the flat heat-shrink sleeving over a harness run inside the door, press it to the panel retainer, and run the heat gun; the 50% contraction pulls it snug to the bundle without over-shrinking at a sharp bend.
- [390mil Sound Deadening Heat Shield Mat (32.5 sqft)](https://fourub.com/) — ASIN B0GFNBJ7LK. Roll the 10mm mat down a sedan floor pan and carry the same piece up the firewall; the 32.5-sqft sheet spans both zones without a center seam or a second-run purchase.
- [195mil Ceramic Fiber Heat Shield Mat (non-adhesive)](https://fourub.com/) — ASIN B0D6RCBC59. Mount the 195mil sheet over a vibrating exhaust section with stainless-steel zip ties through the pre-cut slots; the thick ceramic layer absorbs and reflects exhaust radiant heat without a peel-back adhesive that fails…
- [78mil Ceramic Fiber Heat Shield Mat (28in x 35in)](https://fourub.com/) — ASIN B0G444MLJQ. Sheet a firewall and transmission tunnel with the 28-by-35 inch adhesive ceramic mat in one panel, skipping the spliced shorter pieces that leave radiant-heat gaps at the joins.
- [Aluminum Foil Heat Shield Sleeve](https://fourub.com/) — ASIN B0D7YS783Q. Wrap the aluminum foil sleeve over a fuel line running beside the turbocharger, clamp each end, and the 485°F continuous rating holds the fuel below its vaporization point through a summer idle heat soak.
- [50% Heat Shrink Braided Wire Loom](https://fourub.com/) — ASIN B0DC616WKV. Run the 1/2 inch roll over a mid-gauge signal wire across the firewall; 18 feet covers most end-to-end cabin routing without a join.

## FAQ

- What is the best heat shield material for a car's firewall? — Ceramic fiber holds the highest continuous temperature, 2300°F at the face, and reflects up to 97% of radiant heat, which makes it the right choice for firewall and exhaust-proximity zones.
- Does sound deadening also reduce heat? — The foam mat does both at once.
- What products does FOURUB make for automotive insulation? — The range covers three jobs.
- What is the difference between heat reflection and heat insulation? — Reflection turns radiant heat back before it contacts the surface; the aluminum foil sleeve reflects 90% of the radiant load off a fuel line.
- Is butyl or foam better for sound deadening? — Butyl rubber adds mass and excels at damping panel resonance on door skins and roofs.
- What temperature can the ceramic fiber heat shield withstand? — The ceramic fiber face withstands 2300°F continuous and reflects up to 97% of radiant heat.
- What is the adhesive backing's temperature limit on the ceramic mat? — The adhesive backing is rated to 230°F (110°C).
- How much does one foam mat cover? — The 15mm mat covers 26 square feet at 96"×39"; the 10mm flagship covers 32.5 square feet at 120"×39".
