Frequently Bought Together

Product Overview

With the ever-increasing cost of energy, it is important to create the most efficient attic insulation/radiant barrier system possible. The reflectix radiant barrier is a key component in achieving just that goal. When installed in an attic system, the product blocks 96 percent of the radiant heat that normally would be transferred to your attic floor. By blocking such a significant amount of heat, your attic floor insulation stays cooler and operates more efficiently. This translates to less air conditioning usage (up to 10 percent) which results in lower utility bills. Attic mounted duct systems also benefit dramatically from the reflectix radiant barrier. Ease of handling is one of the key advantages (no itch and all you need are scissors and a staple gun). Additional applications include cathedral ceilings, walls or as a house wrap (behind brick or siding). The product has a class A / class 1 building material fire rating.

Rated 4.2 out of 5 by 12 reviewers.
Rated 3.0 out of 5.0 by You get what you pay for, The cheapest Radiant barrier on the market. After reading many reviews I decided to give this stuff a try. Mostly because of the cost. This reflectix material is very similar if not the exact material that hospital get well balloons are made of with some added fiber for strength. It is a very thin plastic based material, hold a match to it, and guess what happens. I'm sure that it will do what it says it will do as far as heat reflection, I could feel it during the installation process. However I don't think that it will last half the life of the metal roof that I installed it under. Unless you are on a super tight budget or do not care about longevity, look for a metalized product, like Attic Foil, or eco-foil. As a builder, I cannot recommend this product to anyone.

Rated 4.0 out of 5.0 by I had no problems with this product being flimsy i guess they changed the product or Lowes has a better version, but my Reflectix has fibers running 2 directions every 1/4 inch or so. almost impossible for a staple to miss one. i installed this in a 1800 sq ft home all alone with vaulted ceilings and other tight places. my neighbor bought a thicker product online for less, but it was not as shiny and looked to me like it would be much harder to install around supports, vents, hips, and all the other obstacles in the attic you dont think about until you encounter them. so to me the thinness is an asset as long as you have the fibers.

Rated 5.0 out of 5.0 by Worth it Stapled it easily to the underside of my roof decking w/ 1/4" staples. Getting to the corners of my roof is very difficult, but once there, the product staples easily. The imbedded threads strengthen it nicely. Doesn't tear, but cuts with scissors easily. The combination of this barrier plus barely adequate attic ventilation has made my house more pleasant ... I've got it down to 20 degrees above ambient on the hottest days, an improvement of 10 degrees or more. Feels like my house has a bit more "shade" inside - before, I felt like I was being cooked.

Rated 4.0 out of 5.0 by Good Buy Great product. The material seems to have small pieces of string woven in for stability. The product is very stable yet manipulatable. However it does make it a little bit harder to cut sometimes with my knife. A very difficult install for one person in a hot attic, but that's not the fault of the product, just me the lazy installer. I installed it in bursts of motivation over about 2 months. July 24, 2012
Rated 5.0 out of 5.0 by Excellent product Easy to work with, effectively cools the room. We covered large picture windows with the product, attaching with velcro. Easily hidden with a curtain. Also covered sliding door glass panels. It will be easy to remove the radiant barrier panels when the weather cools down. Much cheaper than blinds or cellular shades! June 19, 2012
Rated 3.0 out of 5.0 by Reflectix Radiant Barrier is too flimsy, tears easily, and only has scrim fibers every inch or so. I ordered this product after looking at several other products, being assured it was substantial and wouldn't easily tear. For example, I compared it to AtticFoil and two other products for which I received free samples. On arrival of my order, I was sorely disappointed in the light weight material, not much more than VERY thin aluminum foil; I could easily tear the product in between the scrim fibers. Unless you just happened to get a staple across the polyester scrim fibers, it would not have held up, and even if you did, I think it would have torn badly because the fibers only ran every inch or so in a diagonal cross pattern. While Reflectix would probably have performed equally well in the radiant barrier role, I believe it would have been much harder to deal with as a self install. While it might have held up in a simple/easy install, with the significant tight spaces I was working, I didn't trust it to hold up to the inevitable rougher treatment I would have put it through.

Rated 4.0 out of 5.0 by online only? this stuff is great. it's versatile. I have used it before. it tends to rip when applied with staples but in my application I used wallpaper paste and it worked real well. August 7, 2012
Rated 4.0 out of 5.0 by strong enough to put up, is perforated even though it says it's not This stuff is reinforced just enough that it's not too hard to put up. However, if you're going to tug on it much, it might be good to put something like a little piece of wood under the staples so they don't pull through, or use long strips of wood at inside corners. If your roof joists are like the one we've got on this older (1914) house, you may want to use 1/4 inch or 5/16 inch long staples. We have a fairly hefty hand powered staple gun, but it can't get 1/2 inch staples all the way in these joists. Perhaps it could if they were softer. I've only got some of it up, but it does seem to me that the side of the attic where it's up radiates less heat, even though usually there's more sun on that side. My main purpose is to lower temperatures for attic storage. It wasn't supposed to be perforated, but it is. The perforations are pretty small, though. I plan to use a fan to pull air through between the radiant barrier and the roof, which is why I am not thrilled with the perforations. For a standard installation they're probably a good thing. Based on my experience so far, I'd be willing to buy this stuff again. May 10, 2012
