Beat the heat

Works great in RV windows not being used and under the bed space /mattress

good product

happy with purchase

This stuff is easy to work with but kinda pricey.

I like this insulation but I will say after I bought it I found some that's a white sided kind and it's quite a bit cheaper.

Great product!

Amazing insulation for my generator top and other many things exposed to the heat.

Sun blocker

Excellent product for sun ray prevention, measures and cuts with standard scissors.

Make sure it's square when you cut it.

Works well to put in the windows for putting the Arizona home to bed for the summer!

Works as advertised

I bought this radient barrier to insulate windows from direct sunlight. They needed to be installed on the exterior because the interior was inaccessable. I used an adhesive to hold the barrier in place on the window and then sealed the edges with aluminum duct tape. Working with it was not bad. It cuts with a utility knife or scissors and is reasonably flexible. It comes in a roll instead of folded so there won't be any creases. And it's double thicker than some other brands. But it is N...

Effective and economical

I had previously used Reflectix to cover the windows of a large RV. It made a difference, winter and summer. I'm currently making occasional use of a transport van as a tent, and am looking forward to crafting window covers for it. Alas, they're 18" tall, and Reflectix comes in 48", 24" - and 16". Alas.

Fantastic product

This insulation was so easy to install and had zero dangerous or messy fibers. We lined the ceiling of our new shed/chicken coop. Easily pushed up between the rafters. Light as a feather and not bulky. I'm elderly so all these features are great. Easily has multiple applications. Excellent value for the price.
