Description

 

Floor & Tunnel Shield II™ solves the problem of needing a high heat barrier to block heat from any source intruding into interiors and damaging components and electronics.

Use as a barrier to reflect and insulate from any heat source. Designed to provide the best possible heat protection in areas where high temperatures are always present and problematic, Floor & Tunnel Shield II limits heat transfer on fire walls, transmission tunnels, floor boards, fuel cells and other areas where heat is an issue.
Floor & Tunnel Shield II provides excellent light weight thermal protection, acts as a guard against track and road debris, and provides sound deadening as well. Constructed with an embossed 0.25mm aluminum face bonded to 3mm composite glass-fiber core and backed with a high temp super strong pressure sensitive backing, Floor & Tunnel Shield II withstands up to 950 °C. The adhesive side holds past 230 °C.

Its improved multifaceted modern aluminum surface offers improved reflection and rigidity and allows for ease of installation - aluminum side must face the heat source. At only 4mm thick, this product can be shaped and trimmed for a custom fit and is ideal for minimal clearance areas. With a unique and patented finely woven glass-fiber backing, Floor & Tunnel Shield II is the easiest, most cost effective way to control thermal transfer while protecting expensive components and vehicle occupants from extreme heat situations and sound.
Floor & Tunnel Shield II can be used on any number of surfaces including, metal, aluminum, carbon fiber, plastic, and more. Multiple uses include: fire walls, under hoods, transmission tunnels, floor pans, fuel cells, and exterior under vehicle locations - anywhere to reflect damaging heat.

  • 0.25mm dimpled aluminum face
  • Protection for engine compartments
  • Protection for painted body parts
  • Comfortable interior at any temperature
  • Hi-temp adhesive for a "do-it-once" install
  • Extreme heat barrier - aluminum side should face the heat
  • Only 4mm thick
  • Use as barrier to reflect and insulate from any heat source
  • Great for exterior applications

*DO NOT apply directly to exhaust components.

Frequently asked questions

Up to what temperature are reflective mats resistant?

Contact heat up to 760 °C and radiant heat up to 950 °C, depending on the product. The range includes THERMO BLOCK fiberglass mats (4 to 12 mm, also self-adhesive and on rolls up to 30 m) and DEI Floor & Tunnel Shield II.

What materials are reflective mats made of?

Aluminium combined with fiberglass or basalt fibre, also in self-adhesive versions. The THERMO BLOCK mats have an aluminium top layer that reflects up to 95% of radiant heat.

Which mat thickness should I choose?

The thicker the fiberglass core, the greater the insulating power: 4 mm for flat shielding with little space, 7 to 12 mm where noticeable insulation and sound damping are desired besides reflection.
