SmartSHIELD -5mm 16''X50ft Reflective Insulation Roll, Foam Core Radiant Barrier, Thermal Foil Insulation - Engineered Foil

I bought this to insulate my windows & doors. Let me just say that this is a VERY GOOD QUALITY PRODUCT!! I decided to spend the extra money & go with the 5 mm thickness & I'm VERY HAPPY WITH IT!!! The temperature in my house has gone down at least 8°F since Installing the insulation. I am very happy with the overall value. I can say it is very heat resistant because I am also using it to insulate the exhaust from one of my inside Portable AC units & with it on there, you CAN NOT FEEL ANY HEAT COMING FROM THE EXHAUST HOSE.It is pretty easy to manuver to cut to size. It actually has pretty good sound insulation considering it's not the thickest available. I also did not have any issues with using adhesive on it. I really like the material it's made out of.I highly recommend that you spend a little money NOW to SAVE A LOT, LOT, LOT MORE MONEY 💰💰💰 down the road!!!!

We moved to Texas this summer and it was so hot that the a/c ran all day. We were paying $500/month to cool our 2-story home. I could tell the heat upstairs was coming through the windows so I started looking for a thin insulation I could Velcro over the windows to help. When I saw the video of another pleased customer who used it to insulate the roof of their metal roof workshop. The video showed them using a heat thermometer gun to measure the temperature and it was 20 degrees cooler on the roof the insulation was on compared to the other side without the insulation. I wanted to give it a try. It was more expensive than some of the other stuff but I didn’t want bubble wrap insulation. So I bought a 100 ft roll and put it on the windows upstairs in a few rooms. I also put thermometers in those rooms and they were 5 degrees cooler than the room I didn’t put it in and I noticed my a/c running less therefore my power bill dropped $100. It paid for itself in the first month. Now with winter coming we will see if it also help to keep the heat in.

read about this product on several RV discussion sites. Put this up in our new RV in back side of cabinets and it makes a HUGE difference of temperature in the cabinets. Have only used in hot temperatures. Looking forward to results in cold weather. VERY easy to install. Just cut to exact size and pushed into back of cabinets. Perfect. Highly Recommend.

Original - Not sure about that 5mm. (They rounded up.) Not sure about the full 25'. (Again, they rounded up.) Not sure that I'm sane for paying $75. (Sure seems they like to round up on everything.) Otherwise, the quality is ok, but there has to be other, more reasonable, options for a piece of 1/5" thick foil/plastic foam.Updated - Not sure what happened with my particular order, and manufacturing issues do happen, so the company reached out to help resolve my issue. It's only fair to add stars for solid customer service from a company who appears to stand behind their product and aren't in it for the short-term, profits-only game.

Used to cover two 8'X8' exterior basement doors that tend to be drafty. Using two lengths taped together with the recommended AL foil tape, and stapled onto the door frame, resulted in a solid vapor barrier with no drafts coming through. Found the extra thickness of this foam to help with its rigidity, especially when attaching it to the door frame.The only negative is that the outer foil layer is somewhat fragile. If you try to pull up tape once it contacts the foil, the foil will come up as well. Regardless, I highly recommend this product.

Easy to cut for my RV windows and walls. Much more sturdy and a higher R value than the one with bubble wrap between.

I needed insulation in a structure that I'm using as an office and didn't want to deal with fiberglass and all the mess that goes with that. I figured I would give this a try. Don't hesitate, this stuff is incredible. It's thin and light, reflective on both sides, and it's all in one - nothing else needed. No vapor barrier needed, nothing. We literally unrolled it and stapled it up, cut where needed and used aluminum tape for some corners. And you could tell it worked after just finishing the ceiling portion. Once the walls were done as well, you could really tell. It was 10 degrees last night and it was comfortable in the building. Turned on a small heater and the space heated up within 10 minutes. I'm actually sort of blown away, it's so good that we ordered more to do another space and we will use the leftovers in a chicken coop that we are building. It doesn't smell, doesn't tear, is waterproof, rodent proof, mold proof...but mostly EASY to install. It took two 100 foot rolls to do the entire 288 square foot space. Just cut it with scissors or a blade where needed, easy to get around electrical outlets. Easy to hold overhead while stapling it to the ceiling. I'll never buy fiberglass again.

I have been using this product for myself as well as my clients. I installed on the inside of our garage door which runs 165 degrees on the surface, with this product my inside surface temp is under 100 in direct sun.However 3 out of my last 6 purchased were less than the 24” width and barely 23.5” with what I do that half inch is necessary for a proper fit. I’ll be contacting the manufacturer directly. This is the first issue in 3yrs using/installing this product.

This is perfect, used to insulate garage. Easy to install and does the job!

Bueno pero es más fácil instalar con aderente

Skirted my 5th wheel trailer with plywood on the outside and R12 insulation on the underside and added this product on top on the underside and as we are in Yarmouth N.S. and live in this rig we needed the underside to be impervious to freezing and it is doing an amazing job. Also have a small ceramic space heater under the rig but have seldom had to use it. Also great if you need to cover the inside windows but we have thermal windows so we don't need that. Easily installed with staple gun. Highly recommend.

Been using in RV during winter to cut the cold coming in from certain spots, including windows.
