Highly recommended for Rv windows
This worked great on my rv windows. I cut it to fit, stuck it behind the shade, and it worked perfectly! No need for the sticky tabs, can take them down and up very easily! It’s keeping me a good bit warmer. For the price, it’s a cheap fix that actually works!

Awesome for making sun blocking window panels!!!!!! Sturdy product :)
Awesome! Used to make sun blocking panels for windows. Windows are 36" x 78". One panel is 8" less wide due to portable A/C insert. Measure window twice. Cut once. Used staple gun to attach 1/2" square dowels to vertical edges. Easy to pop in and out of windows. Have taken in and out many times over past month - very sturdy material!! Will be easy to roll up for storage. Seriously easy and helpful. Decreased room temperature by 15 degrees in upper rooms that get afternoon sun and sit above lower level's asphalt shingled roof. Very noticeable difference!!! Looking forward to less $ on power bill. Wish I'd have made these years ago!

Measure the area to be sure you're getting a big enough piece.
Served the purpose I wanted. I use a crate for a dog house. I covered the outside of the crate with this, taped it with some tough weather resistant tape, put the self warming pad in there, and it is working well. I sometimes fall asleep and wake up to him being wet. This keeps him warm and dry until I get to him.

Reliable product
Perfect for covering windows. Dramatic reduction of drafts and leaking warm air to the outside. I was able to do 2 1/2 windows with a smaller roll .. will be ordering the larger roll to finish the rest up. Got 8 windows to cover. What’s already done has shown wonderful improvement in draft reduction. The privacy is nice too

Great Purchase!
I just applied this bubble insulation to my large metal frame windows. I put this along the bottom of the window where I could feel cold air coming into my apartment. I am amazed how well this works. I no longer feel the draft and it's easy to apply.

This Winter has been a rough one. Sunroom is not 4 seasons yet dogs enjoy sleeping in the cool room. Not cold room. Purchased this item to cover windows and within 2 hours, room temp warmed up. Easy to hang, good quality. Will buy again

I’m very pleased with the results. I used them to insulate my basement ceiling. I have a rock wall basement and it is doing the job it is suppose too. Making my floors upstairs a little warmer.

Worked great. Possibly thinner than expected but is keeping heat out of rv windows
