## Customer Reviews

### ⭐⭐⭐⭐⭐ First class product for the insulating my 2 RV AC plenums
*by R***A on September 1, 2021*

Used on My 2 RV AC plenums...I just cut to size on all the different surfaces & then used foil tape to put if all together. It really made the efficiency of them in AC or Heat Pump operation better as well as making them quieter damping the tin.

### ⭐⭐⭐⭐⭐ Excellent Product
*by R***N on October 21, 2022*

Used it to line my hot air furnace. Job came out better than original. One sheet covered everything. Price was awesome. I will keep this in mind for future projects.

### ⭐⭐⭐⭐⭐ Worked great
*by J***E on April 20, 2022*

Used to convert an old metal cabinet into a hobby oven. Did a great job of insulating it, the outside of the cabinet is cool to the touch when 500F inside. Easy to cut with kitchen shears.
