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 10 mil aluminum face bonded to 1/8" composite glass-fiber core and backed with a high temp super strong pressure sensitive backing, Floor & Tunnel Shield II withstands up to 1750°F. The adhesive side holds past 450°F. 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 3/16" 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.

    Weird application and works like a champ

    Posted by W. Carver on Nov 13th 2020

    I have this heatshield inside of a process oven to lower the heat loss through a thin section of the casing and stabilize temperatures. It seems almost magical how much heat this thin little sheet can reflect! I've ran the oven consistently at 650+ F with zero issues so far.

    Extremely high quality heat shielding.

    Heat shield is nice and thick but still pliable. The adhesive sticks well to what youll apply it to and I havent had any come loose yet. No heat at all coming through my exhaust manifolds to my intercooler anymore. This stuff is AMAZING!!!

    Tunnel Shield

    Used in an unorthodox application. Put on underside of motorcycle seat to help alleviate heat soak in the seat. Total review is still out, haven't taken a long ride to see if it helps long term. Short rides I can tell a difference.
