Reflective Foil Insulation, Double Reflective Bubble Insulation Sheet, Aluminum Foil Bubble Shield, Radiant Barrier Roll for RV Windows Weatherproofing (23.6''x 10Ft)

Very easy to work with. I bought the big sheets because I had some larger areas to cover. Keeps the heat out nicely. Also included sticky dots to keep it in place. Worked nicely for my RV.

Worked great during the winter storm. Covered two windows and was able to cut to trim around the door frames.

Works great for keeping the wind and cold drafts out of my camper. I noticed a difference as soon as I installed it! I'm sure it will be cooler in the summer as well since it insulates so well. I have tried several different ways to insulates my camper, and this foil has worked the best. It doesn't tear easily, but it's easy to cut and measure. I used velcro to adhere it and it worked out great!

Good product, as described and shipped quickly

This works great in my windows to block the sun and keep the temperature cooler in my room.

Worked well to make window coverings on my van for a road trip.

This was said to keep the cold out. We’ll see. I do want people to know that I only had enough for 3 windows. 2 were 48” x 27” in my coldest room, with the larger one being 60” x 48” in my living room. The coldest room registered 60 degrees before putting up the bubble wrap. After one night temperature in the room is 63.5, better. The bubble wrap is 48” wide so that worked out well. They do provide small round stickies to put up the wrap. They stick well. Easy to cut and install. Seems durable enough so it can be taken down for summer and installed again. Seems like a cheap way to help keep the cold out. The only down side I can think of is that this is opaque so you cannot see out the window.

I taped this to the inside of the storm door that gets the hot afternoon sun. It has made a huge difference in my garage. I used Velcro with sticky tape already on it so I can remove it in winter.

The product was as described and will be very useful!

I live in an old apartment building with poorly insulated, southeast facing windows. I got fed up with having to replace my air conditioners EVERY YEAR because so much heat was blasting through the windows, even with blackout curtains. I decided to give this reflective insulation a try. I decided to install the insulation on the outside of the windows, because it was too hard to get at the windows from inside with all the furniture in the way. You can install it inside if you prefer. I used metal furnace duct tape because it's heat resistant and reflective. I also bought a digital thermometer for my living room so I could see if the insulation made a difference. The insulation is lightweight, easy to handle, and easy to cut. I'm an old single lady and I was able to cut and attach the insulation on my windows in about an hour. The tape was harder to handle than the insulation. After installing the insulation I noticed the temperature in my living room went down by about 10 degrees C. Since then I've observed that my portable AC units aren't constantly running trying to cool the rooms anymore. Hopefully I can stop having to replace them every year from now on! If so, this insulation will definitely pay for itself. I haven't decided yet if I'll take it down in winter. My landlord hasn't complained about the insulation on my windows. Maybe he knows I'm saving him money on hydro. If you're a renter you might want to double check that your landlord will allow you to use this insulation.

Very good temperature isolator Does the job perfectly

This really works well for insulating an inflatable spa. The slightly irregular shape may be due to stretching due to how the sheet is folded.

Will work great.
