Customer Questions & Answers

Is this adhesive backed

I saw that it claims no tools are needed but I didn't see anything about if it was backed with adhesive or how it adheres to the roof with no tools
Asked by: Brian
No. There is no adhesive backing.

Will this work to block cold and heat or just heat?

I want to use this on my garage door and am wondering if it works during the cold months as well as the hot summer months. Thanks!
Asked by: Lin
It blocks the sun, but offers very little insulation value. I do not think it will help very much to use to insulate your garage door. It would be most useful to block the heat from the sun in windows.

Can the product be cut to fit?

I have a weird and somewhat non compliant home with regards to stud spacing. In random areas in varies from 16-24 inches.
Asked by: audiovideofreak
It is very easy to cut to any size. Please note however, that I do not believe this product would be useful for trying to insulate walls between studs. It protects from the sun, but offers very little actual insulation from heat or cold.

operating temperature

What's the highest temperature can this product withstand?
Asked by: ganon
I would think it can withstand fairly high temperatures from the sun, but I would not leave it exposed to something like a radiant heater that is very near by.

Rated 5 out of 5 by from Love this product! I live in Mississippi and this summer was one of the worse. I decided to experiment and purchased this product to put over my windows on the inside of the house. I have shades and sunblock film, but they did not help. While I was installing this over the windows I could feel the difference immediately. It did not darken the rooms and the rooms cooled down quickly. Wish I had tried this sooner. Great product!

Rated 5 out of 5 by from Great product I bought both the rolled barrier and the 2' x 4' precut panels. As I stated in the other review, installation would have been much easier and faster if it were not for having to work around the horizontal & diagonal bracing connecting the engineered trusses together. The rolled barrier was very easy to cut and install for the two gable ends. For my 12' x 16' recording studio, I was able to get both 5/12 gable ends out of one roll, with plenty to spare for patching. I found that my pneumatic staple gun was by far the best for attaching the panels and the rolled barrier. The staples captured both the plastic & metal rods embedded in the barriers, holding them securely to the framing.The hot air layer in my attic is so much cooler now, narrower, and therefore higher up, and the attic floor is actually cool to the touch. This will really help keep my booth ventilation ducts mounted near the attic floor from heating up.

Rated 1 out of 5 by from wrong measurement It was at least 1 1/2 feet short. Distributor promised replacemnt, over a month ago but have not received it.

Rated 5 out of 5 by from A must have! Great for camping! This 'blanket' is a must have for camping out. So much sturdier than the plain sheets now available & specific for the purpose. Holds the body heat in so much better. And it comes big enough that I can cut it to size. Also good for reflecting the fire, either in, or out of, the tent, lean-to, etc... And reflective for emergencies if needed. I can fold the entire thing, 4' X 12', to fit into a flat gallon kitchen bag, and it is light weight for backpacking. Perfect to keep in the trunk of your car for emergencies. It has so many uses. One of those 'Never leave home without it" things! It could save a life!

Rated 5 out of 5 by from Great product Barrier insulation was very easy to install and it reduced the amount of heat radiating into the storage space through the roof.
