ReflectixReflective Radiant Barrier Insulation Roll 24" x 10' – Double Bubble Foil Insulation with Aluminum Foil Layers – Reflects Radiant Heat – Ideal for Window Heat Blocking, Garage Doors & More

i place this on my sliding door of my house every summer and it keeps heat out very well. i use the left over as a windshield screen for the car ...awesome

Made some custom shades for my van very nice

I never use the foregoing expression, but I will make an exception for this stuff. There is eight feet of it up in my bedroom window as I write this, to keep the sun out of my face in the morning, and to reflect the often brutal summertime heat back to the sun. I have insulated attics, roofs, and hot water pipes with this stuff, and it makes a good water heater blanket, though it's even better taped around a conventional fiberglas shroud, in my experience, sealing up the pipes and anchoring the bottom with both narrow strips of Reflectix and aluminum tape.In fact, one can, with a little extra artistic flourish, make one's water heater look like a robot. It's also good for blocking and grounding electromagnetic fields--that much I know. It might even be of some use in constructing a Faraday cage, but I can't say for sure (I don't work for Raytheon, the Ryan Lab, or "The PG and the E", unless I do it in my sleep and they keep the paycheck).--I hope the manufacturer of this product has a commitment to refine the ingredients, as more sustainable plastics and glues become available, and to support environmentally sustainable aluminum mining. The poor Earth is going to hell in a handbasket, and both practical wisdom and the book of Genesis make it clear we are to care for the world around us, whether we view it as God's Creation or simply our home.That said, I would have to rate this as one of the consistently best products of any kind I have purchased in my 71 years.

Reflectix really works. I had the opportunity to try this on a very hot day. First, I cooled the car down using the AC, installed the reflectix in each window, then shut the car off and left. When I returned 30 minutes later, the temperature inside my vehicle was 2 degrees cooler than when I left. Now this was in the morning and temps outside were mid 80’s by then. Hot and dry. I don’t know how long it will remain cooler inside as the temperature outside goes up. We’ll see. But, I was surprised and am hopeful as the summer heat intensifies.

We used this in our travel trailer. This has no actual insulation value but does reflect some heat due to its shiny surface. We used it in the windows to prevent sun fading and in the upper cabinets to try and prevent heat buildup. It definitely blocks light, and the cabinets seem somewhat less warm. The only downsides are cost and the strong tape needed to secure it.

I cut and used this to cover my 6 foot portable ac exhaust hose in my bedroom. I purchased the ac last summer and this is my first experience with a portable style. I live in the desert southwest where 105 is a mild summer day. Ugh! The ac put out a lot of wonderful cool air BUT the exhaust hose put out a lot of terrible heat into the same space. It seemed so counterproductive to me. They do make sleeves to cover the exhaust hose that you can purchase for 85.00 and up. I only paid 200 for the brand new ac. I don't like to buy things that can be taken care of in a cheaper way. I cut the pieces and fit for the curves in the hose. I was able to use full pieces on the straight parts of the hose. I used aluminum duct tape that can withstand heat to tape the pieces together. It has held great! Our 110 degree days did not loosen the tape. Yeah! I can't tell you just how much this allowed my ac to cool my bedroom even more. I was so impressed that I bought another roll and did my children's bedroom ac exhaust hose. The baby monitor detects its 10-12 degrees cooler in the room than before I covered it. My electric bill also dropped 34.00 compared to last year with all things the same inside and outside. I highly recommend anyone using a portable ac covers the exhaust hose with this product!

I purchased 5 rolls of reflectix for my 5th wheel windows. Prior to installing my rv ac struggled to keep up in our recent, stupid hot, Texas heat and the air temperature was noticbly warm. After, WOW what a difference. I immediately felt cool air and one of the massive super slides facing SW gets direct sun for 3 or 4 hours in the late afternoon and just the day before I installed radiated heat from 3 feet away & the 8 windows got so hot you couldnt touch them! Its no longer hot!I cannot get over how well this stuff works...it is thin as others have mentioned, dont let that discourage you, it works! I bought the 24" wide rolls for my application. I secured with velcro that I cut to 1 inch lengths and used hvac tape to attach the piece work I did on a few windows.I am a believer & highly recommend this productShipped fast too...Works great does exactly as advertised

This is a great product, and I wish I would have thought of buying thermal drapes/blackout drapers earlier in my renting career.I live in an apartment in Humboldt County that was built for high 40-degree weather at night. The last few months the temp has dipped in to the low-40s, low-30s, and high-20s. I had my thermostat set to 64-66 degrees with no drapes or blinds for my windows, and my utility bill was going to be $527.I bought this Reflectix and thermal drapes for both bedrooms, lowered my temp to 61-63 degrees and my utility bill has been $133 (bought the drapes and Reflectix halfway through the month), then my utility bill was $112 last month. I am also not really using my oven (just the stove top), and I bought a good toaster oven that can bake/air-fry/toast/warm/convection bake etc.I put it over the windows like drapes, using thumbtacks to hold it on the wall, the clothespin is so I can lift up the Reflectix and clip it in place up top, and then it lets some sunshine in.The Reflectix and drapes keep the heater or AC inside, and keep the heat or cold out. The only way to circumnavigate the political grid-lock and corporate greed is to weatherize your home or apartment with affordable options like these.
