Double Reflective Insulation Foam, 48"X 10 Ft Window Radiant Barrier, Aluminum Foil Bubble Roll For Keep Heat, Thermal Shield - Engineered

The sheet is easy to work with and cut to size. The velcro stickers make applying it to surfaces fairly easy.It does insulate well. I used it for a new attic access cover and on a hot day there was no difference in the temperature (laser thermometer readings) of the cover and the ceiling a few feet away.

great for windows that are old and drafty. keeps heat in during cold, keeps heat out during extreme sun/heat.

Contre le froid, ne vous attendez pas à des miracles,..pas à-13 en tout cas....en bas des armoires..Mais je présume que a -5 Ce doit être bien. ...

Product is great for window insulation. Live in a cold climate and really helps keep out the cold and save on energy.It is easy to cut to fit. Has adhesive tabs for ease of use for sticking directly to window. We personally cut to fit the whole window and frame so that we press into the whole window to fill in all gaps. It definitely gives a fuller coverage of any air leaking in or out.We duck taped remnant pieces to other pieces to create the size needed with no waist.The thickness is perfect. Not to thick that it won’t shape to window and frames but it is thick enough that you can’t feel the weather through the windows.This item has definitely helped with staying warm through the extremely cold weather recently.

This shows a roll- I’ve used this product many times and know that folds compromise the product a bit. I saw the roll and ordered it- I received the product in a folded manner. It did have some Velcro tabs- which I didn’t need for this application, but will use. Just beware- I have used this product previously after folding and the folds compromised the light block at some of the folds. It is still a good product- just wished it wasn’t crimped into folds.
