DEI Reflect-A-Cool is constructed of fiberglass material backed with a layer of aluminized reflective foil to handle direct continuous temperature of 400 degrees Fahrenheit and has many uses such as covering firewalls, marine engine compartments, RVs, in the tub of a racecar where typical mechanical fasteners cannot be used, and industrial applications. Reflect-A-Cool can be trimmed to fit just about any shape. Just measure, trim, face reflective side towards source of radiant heat and remove self-adhesive backing. It’s that easy.
- Protect wires, cables, hoses, pipes & tubing from radiant heat sources
- Direct heat protection up to 400 degrees Fahrenheit and radiant heat protection up to 2000 degrees Fahrenheight
- Self-adhesive backing with release liner for easy installation; Virtually no clearance needed
- Moisture & solvent resistant
- Use to cover firewalls, marine engine compartments, RVs, or in the tub of a racecar where typical mechanical fasteners cannot be used
- fit type: Universal Fit

I put this on a temporary panel outside of some ladder bookcases that are 6″ from my emergency back up wood stove and the surface is cool to the touch. Prior to installing it the shelves got really hot so that’s why I added a barrier. Works amazing. Super sticky and rolled out easy with a squeegee on the rough side of melamine. No odor too!

Good product when used within its limits. The material is rather thin, sort of equivalent to disposable aluminum baking pan gauge metal with super sticky flypaper on the back side. You can apply it to surfaces that you’d like to help deflect heat, but DO NOT allow it to directly rest upon the hottest parts of the engine or exhaust; RADIANT heat is deflected, but CONTACT HEAT will damage lots of materials, even if the damage is gradual. The material tends to curl onto itself when you peel off the adhesive revealer paper, so peel slowly and in warm environments. GLOVES are helpful to keep from polluting the adhesive. If you cut two pieces and stick it adhesive-to-adhesive, you can create a pretty thick shield that you may then wrap around critical tubes/wire bundles closer to the engine and provide maximum thermal protection. Secure in place with stainless steel zip ties for best results!

This material does not reduce heat. I have a simple test case with a hair dryer, the metal sheet under my van seat with reflect-a-cool applied and a thermometer. The heat keeps rising on the side I want to protect within minutes. How will this shield reject heat from an engine?I understand being told that aluminum reflect heat, etc. But my goal is to keep the engine heat from reaching inside the van. This was a bad purchase and waste of money. I can’t understand how reviewers say it work. Could it be mind over matter? Perhaps having an added layer of 1/16″ fiber would work if welding blankets work. Although I never used one and is yet to see for myself. The tunnel shield with the hard aluminium and fiber material works.I am happy to share my honest review.

I would have given it 5 stars except for the fact my 24” x 24” piece was folded into a 6” x 6” package by DEI. This will be used in an exposed area so the creases for the folds will be showing. Not something you want to look at on a custom build.
