Great stuff. Easy to work with and economical. Only recently installed in lower cowl, so cant rate longevity of product in use. Will adjust rating if insulation doesnt hold up over long time usage.

Adheres well in my fiberglass cowling. Was easy to apply. Used it to protect the fiberglass from the direct heat of the cylinders. Now lets see, how well it lasts in the long run.

I ride a KTM 1290 SA with a serious problem with heat radiating off of the engine head that is just below the seat. Talking to a custom motorcycle seat builder, he suggested this product and it works great! Im much more comfortable now, which means Im less distracted and likely a safer rider. Great flexible product thats easy to cut, shape and adhere to items that arent flat. Quick delivery, but really overpacked.

I used this heat material to protect the inside of a RV-9 cowl. It was easy to apply and I was able to work it around some slight bends. With a few relief cuts it looks great. The material is strong with insulation under the foil. The adhesive seems to be strong.
