Product Information

Full details

The Design Engineering Floor and Tunnel Shield is for automotive enthusiasts and fabricators seeking advanced thermal and acoustic insulation with minimal space requirements. Its key benefit is its ability to withstand extreme direct temperatures up to 950°C and block up to 50% of road noise, while being only 3/16” thick. A potential caveat is that while versatile, it requires careful cutting and shaping for optimal fitment in custom applications.

Extended Product Information

FAQs

What is the maximum temperature the shield can withstand?

The shield is designed to withstand direct temperatures of up to 950 Degrees C (approximately 1742 Degrees F).

How much does this shield reduce road noise?

The shield is capable of insulating and blocking out up to 50% of unwanted road noise.

What are the actual dimensions of the shield?

The material is approximately 3/16” (about 4.76mm) thick, with a 10mm embossed aluminum face bonded to a 1/8" composite glass-fibre core.

Can this be used on the exterior of a vehicle?

While designed for under vehicle use, its primary function is heat and noise insulation from the engine bay or drivetrain. It can act as a guard against road debris, but its adhesion and material may not be optimized for direct, long-term exterior exposure to elements like UV and moisture without additional protection.

Is the adhesive backing permanent?

The high-temperature pressure-sensitive backing is designed for strong adhesion in demanding environments. Removal may be difficult and could potentially damage the application surface.

Can I overlap pieces of the shield?

Yes, pieces can be overlapped. For best results in sealing heat or noise, ensure a tight overlap and consider using a high-temperature sealant along the seam if necessary.

What tools are needed for installation?

You will need a measuring tape, a sharp utility knife or heavy-duty shears for cutting, and a clean cloth for surface preparation. A heat gun can be helpful for forming the material.

Troubleshooting

Adhesive not holding securely

Ensure the application surface is thoroughly cleaned, dry, and free from any oils or contaminants. For extreme temperatures or vibrations, consider supplementing with mechanical fasteners.

Difficulty cutting the material cleanly

Use a sharp, heavy-duty utility knife or aviation snips. Score the material multiple times for cleaner cuts. Ensure the material is flat when cutting.

Shield not conforming to curved surfaces

Gently warm the material with a heat gun (use caution not to overheat) to make it more pliable for conforming to complex curves. Apply firm, even pressure during installation.

Pros and Cons

Pros

  • Excellent thermal insulation capabilities for extreme heat.
  • Effective sound dampening reduces cabin noise.
  • Thin profile makes it suitable for tight spaces.
  • Durable construction ensures longevity in harsh conditions.
  • Can be easily cut and molded for custom fitment.

Cons

  • Requires precise cutting and fitting for optimal performance.
  • Adhesive backing may require additional fastening in very high-vibration areas.
  • Embossed pattern may not suit all aesthetic preferences.

Setup, Compatibility & Care

Setup:

  1. Measure and Plan: Determine the exact area requiring insulation and carefully measure its dimensions.
  2. Cut to Size: Using sharp shears or a utility knife, carefully cut the shield material to the required shape. An embossed pattern allows for trimming along lines.
  3. Clean Surface: Ensure the application surface is clean, dry, and free of grease or debris for optimal adhesion.
  4. Apply Backing: Peel off the protective backing from the high-temperature adhesive.
  5. Install Shield: Firmly press the shield onto the prepared surface, ensuring good contact, especially around the edges.
  6. Additional Fastening (Optional): For extremely high-stress or vibration areas, consider using rivets or high-temperature mechanical fasteners for added security.

Compatibility:

This shield is compatible with most automotive applications, including:

  • Steel, aluminum, and composite body panels.
  • Firewall construction.
  • Transmission tunnels.
  • Floor pans.
  • Fuel cell protection.
  • Engine bay components requiring heat shielding.

Care:

The material is designed for long-term performance and requires minimal care. Keep the surface free of excessive dirt and grime. If cleaning is necessary, use a damp cloth. Avoid abrasive cleaners that could damage the aluminum face.
