BBTOHeat Reflective Sheet Adhesive Backed Aluminized Fiberglass Heat Shield Tape Protection Barrier Heat Shield Resistant Material for Hose and Auto Use Heat Insulation Sheet(Silver, 48 x 71 Inch)

I situated this lightweight, heat-reflector material on the wall behind my toaster oven/air fryer combo where the heat vents are on back right side. I did NOT peel off the entire backing to expose the sticky -- instead I peeled off just a half-inch strip of backing to expose the sticky across the top and the bottom -- and then also added an X-cut-out for the oven plug to come through as well. My electrical outlet is just a fraction to the left of the oven heat vents, but I didn't want the outlet and the wiring behind/inside the outlet to get a constant dose of heat every time I used the oven, so I protected it with a small X-cut flap opening for the electrical plug to fit through. As a pattern guide, I first cut a paper bag the exact size of the reflective material and situated the paper bag on the wall to mark where the plug needed to come through -- this ensured where I needed the X-cut-out for the plug to come through. I then used the paper bag pattern to mark the reflective material and make the X-cut (and recycled the paper bag from there.) I kept the left and right sides open/no sticky used on the sides, so that air could flow and dissipate if there was any heat build-up. I also make sure the cord doesn't rest on the body of the oven when I use it. In my pics, it looks like the cord is touching, but it's just the angle of the pic, the cord isn't touching. These ovens get very hot. It all works well -- there is no heat build up behind the oven/on the wall/on the outlet -- as it reflects the heat away and it then dissipates all around and protects as designed.

The air gap matters. If you can find a way to put some air in between the component you want to stay cool and the heat wrap you'll have success with this. If you put the heat wrap directly on the component you're trying to protect you're not protecting it at all. You don't need much air but direct contact defeats the purpose of it entirely. I used it under the hood to isolate my intake tube from the high temps of the engine bay. I also used some in the rear patch area to isolate my water box for the air to water in a cooler from the heat of the Sun heating up the rear end. It's a very thick material and definitely feels like it's going to last very long time. High quality and durable material like this typically costs triple the price. I didn't actually use the adhesive feature so I can't speak to that but the effectiveness of it makes it a good buy even if you have to supplement the adhesive in some form.

I bought this to keep the direct sunlight off my starlink case. (I don’t have enough room in my service truck to keep it inside) the problem I was having was the case was getting too hot, in fact the satellite was too hot to even touch. I stuck the material, which is very sticky and will form to almost any shape. Now my starlink stays pretty cool even if my truck is under the sun all day

Came rolled up with no creases. Easy to install. Worked great and stuck to the inside of side plate to protect against hot exhaust muffler on my 2001 Suzuki DR650SE.

I have a studio monitor speaker setup right next to my radiator. This stuff keeps ALL heat away from my speaker...its perfect. I've had it slapped directly on top of the radiator for the last 2 months without any issue.

Tape is very fragile to crinkling and the adhesive is not particularly strong

This works good for engine bay locations where radiant heat from exhaust can burn or melt hosed, tubes and wiring harnesses. Anywhere there is radiant heat within a few inches of wires, hoses or even pipes and cables. This doesn't necessarily insulate as much as guards against high heat components that can do damage. Tricky to work with as it in sheet format, sort of like thick shelf paper.

DOES NOT COME ON A ROLL! ITEM MISREPRESENTED!ordered this to use as dress up hood insulation, looks terrible because it came folded up. Basically worthless to me because of the creases all over it.
