MRPAPA Double Reflective Insulation Foam, 48" x 10 Ft Reflective Window Radiant Barrier B2 Fireproof Bubble Insulation Roll for Keep Heat, Thermal Heat Block Shield - Engineered Foil

Cut pieces to fit a window or glass door with a little extra to hold in place. In the summer block the Sun's rays. In the winter hold in the heat and block out cool air outside. It's a no brainer!

Love this insulation! I used it to place in my windows during the summer when the sun hits them to keep the heat out and it works so incredibly well! It's easy to cut and tape together as it has a pattern on it. It's a great thickness as well. It's going to help me keep my air conditioning off this summer, I can already tell as it's already reduced the heat in my house as well as my electric bill.

Excellent product. Immediate cooling upon hanging. Windows are old and sized at 47” by 74” that allows for a lot of heat and cold to come in. For the first time my room air conditioner was able to cool the area better then ever. Easy to cut

Bought this to reduce interior Arizona summer heat. Did keep the temoerature down some. Found out after return in the fall that adhesive on the velcro had melted. Will use again next year, but will put them on the outside between windows and sun screens and not use the velcro.

Really like this, I used it not only on one of my house windows, but I also cut a strip to put on the dash of my car. After reading about dash mats and other items to protect the dash I decided this one was best.

Sturdy and used to block sun inside RV.

Good product to reduce heat in garage. Easy to install and cut to size.

ZERO STARS NEEDED. NOT double thickness. I specifically ordered this because it SAYS it's double thickness and it's literally barely thicker than a sheet of paper. It's not going to keep the heat out of my RV cockpit in triple digit temps any more than paper would. The stuff you can get at Home Depot/Lowes is far better quality and thicker, too. DON'T WASTE YOUR MONEY ON THIS PARTICULAR PRODUCT FROM THIS LYING SELLER. Apparently seller doesn't know the difference between thickness of a product and it having reflective paper thin foil on both sides. I wanted DOUBLE THICKNESS BUBBLE WRAP between the reflective foil and that is NOT what this is.

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. ...

The insulation material itself is fine. The included velcro pads included with it did not work at all. The adhesive unstuck within hours of installation.

Insulation is good. But missing the velcro pads to mount to windows
