Reflective Bubble Insulation Sheet, Double Side Aluminum Foil Bubble Shield, Aluminum Foil Thermal Insulation Radiant Barrier for Windows, RV, Roof, Garage Door (23.6IN X 10FT)

I used this for our RV camper for multiple handy reasons. They are lightweight, easy to cut to size, easy to secure. I wanted something to darken our camper for better sleeping, nothing like the little kids waking up at 6AM because its bright out or not going to sleep until 10:00PM because it just got dark, or parked right next to a glowing streetlight. But it also makes a HUGE difference in keeping so much heat out from the sun. We keep them in the windows when the camper is in storage and it never feels overly hot in there. Or if our big windows are facing direct sun on a 90º day, I put them up to keep the inside comfortable! I've cut to so many sizes, secure them to the window frame using sticky velcro pieces.

Does what it says on the tin. Cannot complain.It also cuts very easily, which is nice if you've got multiple projects.

My front door faces the south and in winter the sun is low in the sky and shines under the porch roof and halfway up my door. The storm door is full view glass and it bakes the wooden door behind. This is the only thing I have found that really keeps the wooden door from geting so hot you can't touch it. It is very difficult keeping varnish on the door. With this bubble insulation the door is barely even warm now. The Bubble insulation doesn't look great like that but I can take it down later in the year when the sun is higher in the sky when it doesn't shine on the door. The bubble insulation is easy to cut with scissors and is lightweight, I hung mine by making a sleeve on the top end with a paper stapler and sliding a small curtain rod in it and hanging it with string on each end. There are fold lines visible in the material where it was folded for shipping that seem to be permanant, too bad they couldn't roll it up for shipping. Overall, it does what I wanted it to, not sure how long it will last in the direct sun. Good luck and God bless

First off, this stuff can lower the temperature of a hot RV by 20+ degrees versus using nothing at all on a hot day. Even with good blackout shades and curtains this stuff can help lower the temperature in my tests by another ~7 degrees on a hot day. That is great and well worth it!To get it to work well for me, I did the following.1. I cut it to each window size perfectly and use gorilla glue to glue on about a dozen small rare earth magnets all around the edges to stick it on to the window frame. The reason I used small magnets and more of them is so that the glue is strong enough to hold them onto the material and it comes free from the frame without ripping the material because those big magnets get strong and would rip it.2. I get them to tuck as far against the window itself as possible for maximum light/uv reflection. I also treated everything with 303 protectant to protect it from getting all crumbly as these things have a tendency to do. ArmorAll or the like would work too I'm sure. This makes them last a good long time before you have to replace them.3. Before I treated them, I spray painted one side black. I did this so at night I could turn them around to make sure no light shows outside the RV and during the day I could use the reflective side to keep the sunlight out.I hope this helped!

For my RV Windows. Works okay but I thought it was a bit thinner than stuff I had bought from the RV dealer at about the same price. Good enough value I suppose.

Worked well for insulating a/c during winter

Wonderful product

works great on the doors
