Customer Questions & Answers

Perforated or non-perforated?

Does anyone know if this product is Perforated or non-perforated?
Asked by: Briwilk

What is the "R" factor?

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.

24 in. x 4 ft. Radiant Barrier (50-Box) is rated 4.3 out of 5 by 24.
Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Relatively easy to install. Performs as promised. Works and installs as described. Rafters that are spaced more than 3/4" or so more than they should be will require additional strategy. They can be stapled but I found if they remain flush to roof, they conduct more heat to attic. Tacking 1" x 2" strips to rafters in these situations worked for me. Otherwise, they spring into place beautifully!

Rated 5 out of 5 by from Easy and simple in the right home We started using this in our attic. It's simple to install and takes little time. The time consuming part came when we needed to make diagonal cuts for our hip roof. That was neither easy (wasn't too hard either) or timely. I wish in our attic we had done the sheets of radiant barrier and just used the staple gun. Also, our rafters weren't always evenly spaced (some needed shimming with 1/2" x 2" strips). The corners of our roof were spaced 16" centers too. (We did end up just buying a box of those, but still had LOTS of cuts.) Now, in my parents home - a nice ranch style home with a gabled roof, ridge vented; and the rafters were nicely spaced at 24" centers - this installation was a breeze. Did just under four boxes (4 sheets left over) in 2 hours. Wow!

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Fast and Easy This is the easiest install you could ask for.I had no issues at all. You bend the panel to cause the tension rods to flex, you place it between the rafters and release--it's that easy. It's also easy to re-position if you need to move it too.

Rated 4 out of 5 by from Easy to install, but be careful I installed these on the underside of an attic roof. It was easy when the spacing was 24 inches, but some sections had an extra 2 x 4, making it a tight fit. Best to wear gloves and beware of the wires, which can scratch. You'll also need a staple gun to tuck down for a flat fit.

Rated 4 out of 5 by from Easy to Install.. Worst Part Is the Attic I'm in Texas so I'm looking forward to the idea of cooling down the attic. I'm waiting for the summer to get here so I can really see the difference. The worst part of installing these panels is having to go into the attic. These are a lot sturdier than I thought they would be when I ordered them. This is great considering I had to do quite a bit of tugging sometimes to get them to fit in certain areas. Very little problems with tearing and whatnot. Sometimes if you are too hard on them you have to watch out for the metal rods inside popping out. You will definitely need gloves when working these because the metal interior would do a real number on your hands if you don't. You will also need a sturdy tool to cut through the inner wiring. Scissors wouldn't last one panel. Easy to install. Mostly hold themselves up accept in those few areas where the rafters are irregular in size. Then a couple of staples do the trick. Easy for one person to install unlike the rolls. The only negative thing I can say is they don't install themselves.
