Reflective Insulation Foam,48" x 10 Ft Window Insulation for Summer Heat,Aluminum Foil Bubble Insulation Roll for Keep Heat,Window Insulation Kit for RV, Thermal Insulation Cover for Window.

Love this stuff. Our bedroom in west facing and above an all brick garage. The sun pouring in, even with blackout curtains caused our bedroom to heat up. This thermal barrier reduced heat by 90%. Easy to cut to size and comes with handy velcro stickers

I liked it so much I did a second purchase and going to do a third. It is very easy to cut. I sew so have rotary cutter which is amazingly easy to get professional cuts. One of the reviews stated it rips easily. Did they use it outdoors instead of indoors? We use it indoors and it works great. Easy to fit and tape with just painters tape. One word of warning though, while painters tape easily removes from most surfaces, it does not remove from this reflective foam. It will tear. Love the reflective light and decrease of heat loss. I even used it on cold walls wit cutting drafts and warmer rooms. We have home extension with lots of windows which are great to look out, but cold in winter even with low e glass. Very happy with this product. Great for interior windows or walls.

Use it in my camper van for the windows. Works really well to block out heat or keep heat in when it's colder.

Works really well on the camper windows. Keeps the hot sun out. Easy to install. Wasn’t cut for a great fit. It’s thin but it really does a great job. Adhesive seems to be holding well also.

It is folded not rolled, which is not ideal. No size on the package, so I will have to see how big it is when I get it opened at our trailer.
