Review: Expensive, but overall I think it's a pretty decent product - A little pricey but decent, it's already made a difference in my shop and it's not really even that cold yet. A little easier to work with and some others that I've used and it's better than the bubble wrap foil stuff.

### ⭐⭐⭐⭐⭐ Rv underneath warmer
*by S***C on October 31, 2025*

2nd time buying this product. Easy to work with. Using for rv winter skirting. Keeps underneath about 6-10° warmer than outside air.

### ⭐⭐⭐⭐⭐ Expensive, but overall I think it's a pretty decent product
*by P***T on October 17, 2025*

A little pricey but decent, it's already made a difference in my shop and it's not really even that cold yet. A little easier to work with and some others that I've used and it's better than the bubble wrap foil stuff.

### ⭐⭐⭐⭐⭐ Excellent
*by F***J on March 2, 2025*

This is amazing. We put this under our metal gazebo on back deck which get blazing hot in summer and couldn't sit under it. When we put this up with about a 1/4 8n air gap it stopped all the heat transfer. Now it is almost same temp as under our tree. Easy to cut not too fragile. I would buy again. Just use the right doublesided tape
