Product Overview

Reach Barrier 3023 Silvertanium Radiant Barrier is the only non-laminated reflective insulation product available and is so pliable it makes even the toughest job easier. Silvertanium is constructed with highly reflective metallization on both sides and is perforated for maximum performance and breathability. Traditional insulation materials such as fiberglass or foam don’t stop the heat they just slow it down but Silvertanium cutting edge technology stops 95% of radiant heat ensuring maximum protection. It is 30% lighter than other radiant barriers. This insulation is not a multiple-layer laminated product and it will never delaminate and fall apart. The proprietary protective coating will not oxidize or degrade over time, ensuring peak performance throughout the life of the product. At just a fraction of the thickness and weight, this insulation has up to four-times the tear resistance of other brands, making installation dramatically easier. Silvertanium meets all ASTM standards, complies with the international building code and is ideal for: Attic spaces, exterior and interior walls, interior masonry walls, radiant floors, metal and steel buildings, crawl spaces, garage ceilings and many other applications where insulation is needed. This insulation roll is 250 ft. long, 48 in. high and 0.01 in. thick. Installing a radiant barrier may be the lowest-cost improvement that can produce the greatest overall reduction in energy usage and expense.

  • Installing Silvertanium reflective attic insulation barrier is a great DIY project
  • Save on energy costs by reducing energy consumption in your home
  • Entire attic is made cooler or warmer (Not just the living space below)
  • Air conditioning equipment and ductwork within the attic benefit from the more consistent temperatures
  • 100% recyclable
  • Your attic space remains more useable after installation

Can this be used over blown in insulation?

March 17, 2016
I live in a condo that has minimal blown in insulation. The rafters are all visible. Can I install this on top of the blown in insulation, stapling at the rafters, meaning not on the slanted roof rafters but on the ceiling rafters...meaning it will lay flat on top of the ceiling rafters. There will be an air space between the blown in insulation because there is so little of it. (hope this makes some sense to someone! LOL)

Answer: 
In terms of stopping attic heat from making its way into your house this material is not able to do its job if you don't have an airspace between the radiant barrier and the insulation on the floor of your attic. If the radiant barrier is in contact with the attic floor insulation then the heat just conducts from the radiant barrier to the floor insulation.
No air gap = No radiant barrier

Yes, it can be installed over blown in traditional insulations. Traditional insulations work reasonably well with conductive and convective energy transfer, but with radiant energy transfer, such as from the sun passing overhead, they act like a sponge and absorb heat, then pass it on into the living space even after the sun has gone down.

Answer: 
Placing the material directly on top of insulation is not recommended. In this type of installation, dust will accumulate on the foil surface facing the roof. In time, the dust will negate the radiant barrier effect. - PER WEBSITE http://www.reachbarrier.com/faqs/tstcat2

Dear Buddafan: As DIYguy noted, this radiant barrier will help to reduce air leaks into your attic, to reduce heat loss in the winter. That said, it is definitely not as effective as standard insulation -- in the summer or winter. Radiant barriers only reflect radiant (infrared) heat, e.g. heat radiating off a hot metal roof in the summer.
Home Depot sells other solutions that would be much more effective in your condo attic. For example:
(1) Foam board: R5 per inch. If your attic is not used as a storage area, foam board is a very effective solution. For example: TUFF-R Model # 268441 Home Depot Internet # 100322376 Store SKU # 163832 You can glue sheets down on top of the ceiling joists. Add multiple layers to boost the R value. Be sure to carefully seal all of the joints and edges to block air leaks. The 'Windows and Doors' version of Great Stuff foam works well; the cured foam remains flexible to prevent cracks as things expand and contract. See: GREAT STUFF Model # 248312 Home Depot Internet # 100068117 Store SKU # 522661 (Foam board is flammable, however, and must be covered by drywall if your attic is accessible and used as a storage area. Do not install it next to anything that gets hot, e.g. a chimney or exhaust vent.)
(2) Rock wool: R4.2 per inch. Roxul rock wool is also easy to install; you could lay batts down between your rafters, over the existing insulation. This would also be much easier to get into your attic if you have a small access panel, compared to foam board. Plus it is not flammable. See: Model # RXCB301525, Home Depot Internet # 205972559. Roxul is also much denser than fiberglass and reduces air flow. Because it is not flammable, you can pack it into gaps around hot exhaust vents or an internal chimney -- to seal air leaks.
(3) Blown-in cellulose: R3 per inch. You could blow in cellulose on top of your existing insulation. See: Model # INS541LD Home Depot Internet # 100318635 Store SKU # 211904 Home Depot rents the blowers; you don't need to hire an installer. To break the 'thermal bridge' with your exposed ceiling joists, add enough to completely cover them. (Wood is a surprisingly good conductor of heat / cold.)
Before you add any insulation, carefully find and seal all of the air leaks into your attic. Recessed ceiling lights are culprit #1: install Tenmat covers and seal the edges with Great Stuff. See: Tenmat Model # FF130E Home Depot Internet # 204286308 Store SKU # 1000012747. Great Stuff is also good to fill gaps and cracks -- but do not use it near anything that gets hot, e.g. a chimney or exhaust vent.
I hope this is helpful. Effective insulation requires more effort and $$.

Answer: 
They are called joists. Rafters hold up the roof. Joists hold up floors and ceilings. Now that we have that cleared up....8-}
Yes, you can use this on the joists. Make sure that you tape the seams and preferably tape the holes where the staples are.
Most energy is lost through air leaks and this will reduce air leaks.

That is why Reflectix, for example, claims R7 in a cathedral ceiling in summer -- but only R1 in winter. Even though the air next to the ceiling is warmer than anything else in the house, it is not 'radiant' (emitting infrared energy) and the shiny surface has almost no impact.
I hope this clarifies things.

Answer: 
Dear Phil: Good question! First, "radiant barrier" insulation is only effective if you build / create a sealed air barrier on one side. Second, it is much less effective in winter vs summer because there is little radiant heat for the shiny surface to reflect. (Cold cannot be "reflected".) Reflectix, for example, claims R7 in a cathedral ceiling in summer but only R1 in winter, in the northern US.

Home Depot sells a number of other insulation products that are effective, winter and summer, which you can install yourself, e.g. foam board, Roxul rock wool and blown cellulose for attics -- all of which we have used on a number of projects. For example see:
Foam board: Owens Corning Model # 52DD Internet # 202085962 Store SKU # 307101

Dear Froggman: This has been recurring question in the construction industry with aluminum siding, foil faced polyiso foam board, radiant / reflective barrier products, etc. -- but no professional studies have been done that I am aware of.

Any layer of metal will have some impact on radio frequency signals. That said, there will still be many ways for cellular radio signals to enter and leave your home, e.g. via walls, windows and doors. In most populated areas, a cell phone can connect to 3 or more antennas located in different directions. So a radiant barrier is likely to have a noticeable impact only if you already have weak cell coverage.

If you find that this is the case, cell signal boosters are available to increase the signal strength inside your home, e.g from WeBoost (AKA Wilson).

Before you invest in any radiant barrier, also read up on where they are effective, installation requirements and sealed air gaps, and the lack of performance in winter -- because 'cold' cannot be reflected and warm air in your home is not radiant.

I hope this is helpful,

Mark

Dear Scort: According to the spec sheet, the emissivity is <0.05 based on the ASTM D1313 test.

As a number of real-world studies have noted, however, the performance of radiant barriers decreases steadily as dust accumulates on the surface.

Rated 4.6 out of 5 by 34 reviewers.
Rated 5.0 out of 5.0 by Tuff stuff Purchased this and installed in my shed just tacking it to the bottom of the rafters and the wall studs, then installed Masonite panels for a finished look. Wow, this dropped the temp in the shed by a good 10 - 15 degrees. The product is very tuff, just rolled it around the room, and used a staple gun to attach to the walls. My shed is a 10 x 20, so I used about 2/3rds of the roll to enclose the entire thing. Way worth the money spent, glad I did it. shed is now like being under a tree. June 28, 2016
Rated 2.0 out of 5.0 by Meh? I bought this insulation as a (hopefully) cheaper option than that foil backed rigid foam insulation or installing an air conditioner, in order to keep the temperature down in my garage. The product probably does as advertised, which is deflect radiant heat. It did, in fact, reduce the temps in the attic space by about 10 degrees (105f down to 95f). The problem is that unless there is a place for the hot air to go it will still get hot in the ceiling. I ended up spending about $250 on a solar powered attic fan and it immediately vented the attic and cooled the space down. If you already have a roof vent then this product will probably work better for you than for me. The product is well made. It is tear resistant, easy to staple in place (the stapler is a separate review...Grrrr.) and east to trim. August 15, 2016
Rated 4.0 out of 5.0 by Strong and Flexible The Silvertanium Radiant Barrier is easy to work with, strong and flexible to install around obstacles. Cuts easily with a sharp utility knife. August 9, 2016
Rated 5.0 out of 5.0 by Well worth the money and time to install! The material is Tarp-like and much thicker and stronger than I thought it would be. I thought it was going to be similar to an emergency blanket but it is actually more like a plastic tarp but with a tighter weave. This means that it is not able to be used as a moisture barrier but that it is also much more durable. The way that I used it was for the attic in my house to help reflect the heat back into the house. I rolled it out across the rafters and placed insulation both above and below the barrier. To validate the improvement I timed how frequently my furnace turned on when it was about 45 degrees outside. Before the Barrier Installation: Every 22 minutes After the Barrier Installation: Every 35 minutes For the purposes of my install it is likely that some of my improvements were due to me fluffing up the old insulation during installation, but there was clearly an improvement with the installation of the barrier as well.

Rated 5.0 out of 5.0 by Terrific Insulation The Silvertanium Reflective Attic Insulation was very easy to install and seems to be very durable. I would recommend this product as an addition to the standard insulating materials used for home insulation. December 9, 2014
Rated 5.0 out of 5.0 by Easy to manage & install I put this up over the course of a couple of weekends. It would be a lot easier with two people. Crawl spaces was the most difficult to work in, but that's why they call it a crawl space! I used a manual stapler with a box of 1/4" staples, if you have electric stapler use it, especially in tite corners. I had a head lamp, knife, tape measure, foil tape for corners and parts of ceiling. I think it will make a huge difference for the summer months. February 15, 2014
Rated 5.0 out of 5.0 by A simple do-it-yourself energy saving product. The radiant barrier was very flexible and strong, easy to cut and install. I noticed the attic temperature falling as quickly as I was adding new pieces of the foil. By the time I finished the installation the future master suite was not only significantly cooler but surprisingly quieter. The only tools necessary were a measuring tape, straight edge, scissors, and a stapler. Good investment. June 25, 2013
