Bubble Reflective Insulation Roll To Window For Winter, Double Side Aluminum Foil Keep Heat,59"X 99" Thermal Shield,Rv Insulation.

Great easy to use some of the Velcro stickies don’t stick but they give plenty to help with that. Keeps heat from leaving through the windows, so works well and Velcro makes is easy to take on and off.

I’ve used this product several times! I’m a shift worker, so keeping my bedroom cool and dark so that I can sleep at night is really important. This insulation helps to do just that! This is the second roll that I’ve purchased, but only because I moved and my windows are different measurements! It’s very durable and weighs next to nothing. I just put my curtains up in front of it and you don’t even know it’s there besides being able to sleep comfortably! We’ve put in in our camper windows as well!

I have very old, large dual-pane windows that are inefficient. Adding these to the panes helps keep the heat and sunlight out during summer, making the room much cooler and reducing the need for the air conditioner.

Super thin - the air bubble layer is almost non-existent. The picture of the product shows a roll and arrived just folded up flat. I was planning on adding this to my garage door insulation project but not sure it will be doing much good other than reflecting radiant heat.

Great value, keeps heat in, lightweight and easy to use
