What is the "R" factor?

August 20, 2015
I have used multiple types of insulation in my line of work. R 13 - 16 is standard in walls. R-30 is desirable in ceilings. Can you give me a number that I can compare to other materials available for this application?
I am also curious to its sound dampening ability. I have been asked by many Studio Engineers to produce sound dampening panels that can be placed in a room to damp standing waves. (undesirable reflections at given frequency ranges) I know the latter is a very complex question, but any information given will help me determine its ability for this application.
But honestly, I am more interested in its thermal damping ability.
Thank you.

Rated 4.3 out of 5 by 24 reviewers.
Rated 4.0 out of 5.0 by BARRIER = GARAGE DOOR IT GETS HOT IN TEXAS. I installed my radiant barrier panels on my garage door. I had to cut each one down to size, but that was very easy and adhered using liquid nail. My wife tells me she can definitely feel the change in temperature when she and the kids get in the car every morning. The back wall of the garage is the back wall of our master closet, master bath then bedroom . . . I can tell the difference in the night time temperature in our bedroom. I'M CROSSING MY FINGERS that between this and our attic radiant barrier our a/c units will have a lighter work load. BOTTOM LINE I'm looking to lower our electric bill! July 1, 2015
Rated 5.0 out of 5.0 by Reflective panels fit my needs Found about a 10*F drop in attic temps after installing reflective panels between the 24"OC roof trusses. Still have some additional roof areas to install, so hoping to drop the temps a few more degrees. To facilitate installing the lowest panels in the low angle roof, I used a stick with rare earth magnets spaced out to line up with the steel tension rods in the panels. This allowed sliding one edge of the panel out to the lower part of the roof. I also found it worked best for me to not wear gloves while installing the panels. I could not feel where the steel rods were with gloves. Just need to use caution to avoid getting cut on the rod ends but did 2 boxes of panels with no problems. I used 3 panels on each side of the roof, which is about 22 feet wide. August 6, 2013
Rated 5.0 out of 5.0 by Great product I installed these panels by myself between the joists of my garage roof. It took me only one day. The panels are tough and strong, but the install was surprisingly easy. I set my ladder to the side of the joist, climbed up and bowed it into position. Then I climbed down, turned the ladder facing to the panel, climbed up again and tugged the high end to pull out the buckles where the spring rods had grabbed in a sometimes non-aligned position. You tug and push the spring rods back up against the roof and work it like so and each panel aligns straight and true. Toughest area I had to do was was six joists where the gas pipe for my water heater ran along the rafters close to where roof meets wall. There, I had to bow the panel into place before the gas line, reach around the line and sharply tug the panel down to the meet with wall. None of the panels tore. I was amazed how tough these darn things are. Finished project not only looks cool, it is cool - much cooler. June 5, 2012
Rated 4.0 out of 5.0 by Good iten This was really easy to install and is working great so far. I see an average of 10 degrees higher than outside temps. I'd say pretty good considering Florida weather increases attic temps up 40 degrees higher than outside temps. last summer I could feel the heat radiating through the ceiling inside my home. Now I don't feel any heat coming through. Wait till its on sale online and catch huge discounts. I paid about 45% less than retail for whole house. Even put it over my garage. GREAT DEAL!

Rated 5.0 out of 5.0 by Good product. We changed attic space into a room. We have a roof ridge vent and soffit, but that was it. Installed these from the soffit to the ridgevent, leaving gap at top. Soon as you know how to bend it and push in, was very simple installation. The flow of air is going all the way to the top and out. If the roof ever springs a leak, this should send the water down to the soffit, which was a nice added benefit. We added insulation batts, butted up against it. Compared to the plastic attic ventilation channels which I had starting putting up at the beginning, these let way more more airflow in. I've been up in the roof when it's hot and the plastic ones are hot and these radiant barrier are not, so just by that alone, seems to be doing a better job reflecting heat from roof and allowing air through.

Rated 5.0 out of 5.0 by This stuff actually works I added this to my rafters when I was also insulating the ceiling. I have a temperature laser gun and there is about a 20 degree difference between the wood and the installed radiant barrier. I have only finished about half of the rafter so far. From the part I have completed there is a major difference in heat. On a hot day it is the difference between 95 degrees and about 77 degrees with the radiant barrier installed. I purchased this product when Home Depot had it for the deal of the day and I paid $67.97 for the 50 pack. For this price it is defiantly worth it. You need to order much more of this that you think. It cannot really be cut easily like normal insulation can be. You really need to overlap the sheets at least a few inches (6" to 12") so you need to consider this when you calculate your square footage. October 28, 2014
Rated 5.0 out of 5.0 by radiant barrier I am a woman and it was the easiest ever to install and looks very clean :) March 4, 2015
Rated 5.0 out of 5.0 by Relatively easy install--makes a big difference! I bought during half price one day sale, so got a package for about $80. I bought for my unheated, un-insulated three car garage, about 650 sq. ft. Had to wait for temp to warm to about 30 before trying to install, and got about 2/3 completed yesterday, with about 22 panels left to put in. I noticed putting it in that the garage seemed a little warmer, but thought it might just be me working harder. This morning, with the outside temp at -4 degrees, a jug of water in the back seat of my car in the garage was all liquid- not frozen- so the temp in the garage must have been close to 30. Before the radiant barrier, I had noticed about a ten degree difference between inside and outside temp when leaving in the morning. With the radiant barrier, I estimate 25-30 degree difference. (and I still have about ten feet of garage roof to cover!!) Very worthwhile investment, and a good use of about two hours of time. The panels get easier as you go, as you learn how to line them up, and flex them to slip into place. Easiest when there are no obstructions between joists. Best when joists are evenly spaced with 24" centers, most of mine were well spaced. It would be a lot easier if the stiffened spines inside the panels were marked somehow, so you didn't have to feel for them. Highly recommend this product. Low cost and surprisingly effective. A side benefit- if the wood of your garage roof is dark, as mine was, this stuff also brightens the inside of the garage, reflecting light as well as heat. February 23, 2015
