Product Overview

  • Great for energy efficiency
  • Works well in attics
  • 48 in. x 125 ft. Heavy-Duty Perforated Radiant Barrier
Lower your energy bills with Reflectix radiant barrier. A perfect solution for attic insulation, it blocks 94% or more of the radiant heat that normally would be transferred to your attic floor. That keeps the attic cooler and means less air conditioning usage, up to 10% less, for lower utility bills. Attic-mounted duct systems also benefit dramatically from our Reflectix radiant barrier. It is easy to handle, and can be used in cathedral ceilings or as a house wrap behind brick or siding.

Questions & Answers

I currently have fiberglass insullation for my garage door. If this were mounted behind the fiberglass, against the garage door, would it improve it?

Asked by: Tom
you need the radiant barrier to have one side exposed to the air not trapped between the fiberglass and the door.

Will this product work under bench seats for radiator covers?

I want to build covers for my radiators in my very old house. Will this product effectively reflect the heat from the bottom of the bench seat into the room?
Asked by: Michelle
Just guessing...I wouldn't put it in contact with a heat source directly, but it's made to reflect 95% of the heat. I have it in my attic and notice a big cooling difference than before installation. Need ventillation -- it diverts the heat, not absorbs it, so the heat needs a place to go.

Can I use this on the attic floor which is also the ceiling below before I blow in my attic insulation? I'm refurbishing a 120 year old house and the ceiling boards have some gaps between the boards. I thought that I could install this product on the top of the ceiling boards and then blow in the attic insulation on top of it.
Asked by: Woody
You can do that, but it will NOT work as a radiant barrier. Radiant barriers need at least one face exposed to the air. Stapling this product to the rafters is the best way to use it. However, you can lay it across your attic floor AFTER you fill the joists with blown in insulation. Since this product is full of tiny holes (on purpose) any vapor entering the attic from below will pass through this product and exit the attic via the vents.

Can this be used in a metal barn roof to reduce the heat inside? If so how much of a space between the metal and sheeting would be needed?

Can this be used in a metal barn roof to reduce the heat inside? If so how much of a space between the metal and sheeting would be needed?
Asked by: Joe
Dear Joe: This Reflectix product will not provide any benefit because it is perforated. Think about the physics: the metal roof gets hot in the summer and emits infrared radiation that heats the interior of your barn. You install this perforated Reflectix product, with an air gap between the roof and the Reflectix layer. As the metal roof heats up, it emits infrared radiation which bounces off Reflectix and back to the roof, heating it further, which quick raises the temperature in the air gap. This super-heated air flows through the perforated holes into your barn. In short, you just created an efficient air heating system! Depending on how your barn is constructed, the best option is probably rock wool, which provides R-4.1 per inch of thickness, winter and summer. A board-like version called RockBoard is available with foil or white poly facing; look up RockBoard 60 from Roxul on the Web. Simply add multiple layers to increase the R-value. Talk to your Home Depot's Customer Service or Pro Desk to order this product. Many customers are not aware that Home Depot offers this service -- they sell a much wider range of building products than what is displayed on store shelves. Prices are competitive and Home Depot will deliver to your site or to the store. You may need to add strapping to the barn frame to fasten the Rock Board panels in place. Also seal the joints and edges to block air leaks; HVAC mastic would be best for this large job.

48 in. x 125 ft. Heavy-Duty Perforated Radiant Barrier is rated 4.7 out of 5 by 50.
Rated 5 out of 5 by from Heater Runs About 50% Less They make a really thin and a thick material, but both come in same box. I inadvertently bought two rolls of the thick and one of the thin, but didn't know until I got it home. The thick material is much easier to work with and lays real nice. Both do the same thing. I did the drape method (on the floor of the attic over the insulation) to trap the heat in. Just to be thorough, I also did the between the rafters method (between the rafters and stapled directly to plywood roof deck) on the south facing roof only. This method is recommended for hot climates to prevent a heat cavity. I live in Sacramento so it is a hot climate and it gets somewhat cold too. My heater now runs approximately 50% less. I do not expect to even need AC in the summer as I only had heat problems around 7 to 9pm, after the insulation loaded with heat. Now that I have a barrier between roof and attic, and between the attic and insulation, AC should be a thing of the past. I am told I shouldn't even need my whole house fan anymore.

Rated 4 out of 5 by from easy to install. works? the wrap itself was durable, i am installing in a tight place and often it got caught or pinched, but never tore. only had part of the attic covered (area with most direct sunlight and open space below) before weather changed, and i didn't get overly scientific about before and after measurements, but it did seem that it had an impact in regards to feel and temp in that area. the interior surface was 10+ degrees cooler than the roof deck itself and the heat sensation was less under the cover than where i hadn't completed installing. installed by self doing 6-8' sections running with the rafters as this reduced cutarounds of supports. trick was to make sure i got it tight, i installed on bottom of rafter so airspace was around 6" and i routed the soffit shields above the wrap and left a gap of about 6" at top along ridge vent. circulation seems fine, goal is to reflect energy not block convection action.

I have exposed Kraft paper on insulation in the basement that needed to be covered to meet current fire codes. Material is very tough and provided the needed fire barrier at less cost and much easier installation than drywall.

Rated 4 out of 5 by from a pain to install, but works 1) The material is really tough and stands up to the abuse of installation. 2) We installed it in long sections (4x26'), but I feel like it would be easier to install in 4x4' or 4x8' sections. 3) Has dramatically dropped the temp in our attic on the first day of completed installation. 4) Expect to use more staples and duck tape than you assume. (we used duck tape, not the foil tape. I'm sure that makes the the boogie man, but come on...) 5) I used the opportunity to also add some insulation over/around the ac duct work in the attic and fix a few other things that otherwise go unattended. --Our home is a smaller 2 story house built in the mid 1980s in Texas. We've already noticed the comfort level of the upstairs improving.

This is good stuff and it is sturdier than the 4ftx250ft reach silvertanium. However if you get the roll even slightly wet and let it remain so it will be ruined. My roll got a little bit of rain on it before I could move it inside, not even nearly enough to soften the cardboard tube, just a slight wetting, I let it sit in dry area but without drying it and it ruined the roll. The reflective stuff turns oxidized white looking and its useless. to the person who said he got a roll with manufacture defect I would guess his roll also got wet somewhere.

Product is sturdy and did not tear even though I was yanking on 30 foot runs of the foil trying to get it positioned to begin stapling. The 4 foot width made it a bit of a pain to get it into position at times, but on the flip side that same 4 foot width made coverage much faster. The product did everything I asked of it. I used a laser temperature gun and it looks like there was roughly a 20 degree differential between areas covered in foil versus raw roof (measured from inside the attic). The installation is simple but is always a bit awkward. After a bit of practice it became easier to hang semi-quickly and straight. My only caveats have more to do with the installation itself. It's just never going to be pleasant spending hours up in your attic going back and forth from stretching out to get to the high points and stooping down to get into corners and low spots. Use a dust mask and be sure to do it on a cool day. Hydrate as necessary (you will be sweating more than you think) and be very sure of your footing every step. Take breaks as needed to make sure you are able to stay focused up there. TLDR - it's a solid product just be prepared for the unpleasantness of busting your tail to get it installed.
