EconoHome Double Bubble Reflective Foil Insulation - Reflective Insulation Roll with Metal Foil Cover - Heat Radiant Barrier for Wall, Attic, Air Duct, Window Coverings, Radiator Cover - 4'x125'

My small stand alone freezer I have had for 15 years with No trouble. I opened the lid and all the insulation fell out of its place so I thought what now? did not want to buy a new one, so I bought this to replace the original that fell out and added some freezer tape to hold it in place. To my surprise it works great the freezer is as cold as ever, before I did this the freezer lost like 30 degrees now back to normal at 12 degreesI am very happy with this product.

Used in attic, thank you

I used this to put behind my radiators to help radiate the heat away from the walls. It’s thick and sturdy and was easy to cut without tearing. Exactly what I needed.

It was better than the stuff from Home Depot... It was thicker, and cost about half of what we paid there. Would definitely recommend this product!

This 25' roll of foil coated bubble wrap is a handy material for all kinds of insulation applications. The roll is 50" wide and is easily cut to size for just about any project. I needed a wider roll to insulate a roll-up tarp door in my temporary workspace and this has made a noticeable difference to the time it takes for the space to warm up during the hot summer days. The material is essentially 2 layers of the small cell bubble wrap with a foil backing that has been bonded together giving you a 1/4" thick double bubble layer with reflective foil on both sides. I'm assuming that the product rating of R-24 is a misprint in the description as this is way overrated and bubble wrap of this thickness will usually only be R1-2. The product insert says the R value is 1.27 per m². This product could be layered to increase the R-value but just for reference, 1" thick EPS foam (Styrofoam) has an R-value of about 4.I used duct tape on both sides to join sections together to make an 11' wide panel and by keeping the sections oriented the same way it was rolled up in the package has made the roll up mobility of the door very easy. I did note that the roll I received was about 4" shorter than listed but not a huge deal. Hopefully this will last for the time that I'll need it to but as we're always finding things to insulate, it will probably have extended uses beyond this roll up door panel. At the current price of $59.99, it's a little pricey but you get a over 100sqft to work with. I'll give it 4 stars.

This is perfect for my RV windows. Excellent product and great price. Super fast shipping. Thank you Amazon 😊

Works good.

Not only is this thick, but has excellent tear resistance. I have used both the solid and the perforated version, for when transmission of water vapor is required. In the past in insulating attics I have used sprayfoam on the underside of the roof deck. It makes the entire attic area become a conditioned space, and that is a good thing to do, especially if you have a furnace or ductwork, or plumbing, that runs through the attic.However, sprayfoam is expensive. Really expensive. And it really lets asphalt shingles on the roof bake in the hot sunshine. So I am going a different route. I am using this type of material, alongside the foil-sided bubblewrap, and running them between the top chord of the roof trusses, or in the case of rafters, between them. I am leaving at least a 1" gap between the roof sheathing and the surface of this material.That allows me to have attic ventilation, but the incoming air stays on the underside of the roof sheathing, yet is separated from the air in the attic. I run it all of the way to the ridge, and use an air stapler to staple both sides. I then use a continuous ridge vent.The reflective qualities of this material work best if not used in a horizontal direction. As dust and dirt settles on the material it becomes less reflective, defeating the purpose of a radiant barrier. In my case this does have an impact on convective heat flow, since air will be traveling behind it up to the ridge, and this will separate the interior attic air from that air.But its main use will be to reflect intense summer heat that warms the attic back at the roof sheathing, where it will rise and leave via the ridge vent. Conversely, in the winter this will reflect heat back toward the home's ceiling and keep the air separate from the cold air moving between the soffit vents and the ridge vent.This, combined with regular fiberglass batt insulation, will not only be far cheaper than sprayfoam, but will, in my opinion, be more energy efficient. Just stick your hand in a pouch of this type of material and see how quickly the heat you are producing radiates back to warm you. But if you touch the sides and it is cold outside of the pouch your hand suddenly becomes cold. The difference between radiative heat transfer and conductive heat transfer. The third is convective heat transfer, and that is kind of like blowing a fan into the pouch.There are other places where this is good to use. Garages and workshops are the first thing that come to mind. If you have open-stud walls, or an open ceiling it can either get cold in the winter or really hot in the summer. This 4' roll can make quick work of leaving nice air cavities in the wall behind this material, and with a hammer tacker you can have it up in no time. Not only will it be more comfortable, but the reflective nature applies to light as well. It will be much brighter.This is really good material and from my cut test, and then attempted rip test, it passed with flying colors. Keep in mind I did not order the aluminum version, so this is a comment concerning the metal material only. I'm very pleased with this.
