I want to know if I can use this with vent channels such as Provent by ADO? If so would it go over or under the channel?

Answer: 
It would have to go over the provent channel but I don't think a provent should be used in conjunction with the radiant barrier. An Enerflex panel over the provent would restrict the air flow thru the soffit vents. Check the Enerflex website and Youtube for correct installation.

Answer: 
Dear Twinstates81: Unfortunately the answer is NO. Reflective barriers are effective under a hot metal roof in summer, which radiates infrared energy -- but cold cannot be 'reflected'.
Home Depot sells other insulation products that will be effective for your crawl space, e.g. foam board. The best option is: DOW TUFF-R Model # 268441, Home Depot Internet # 100322376 Store SKU # 163832. You can nail or Read More
Dear Twinstates81: Unfortunately the answer is NO. Reflective barriers are effective under a hot metal roof in summer, which radiates infrared energy -- but cold cannot be 'reflected'.
Home Depot sells other insulation products that will be effective for your crawl space, e.g. foam board. The best option is: DOW TUFF-R Model # 268441, Home Depot Internet # 100322376 Store SKU # 163832. You can nail or screw the foam board panels to the bottom of your floor joists. 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 stop cracks as things expand and contract.
In a garage, however, foam board MUST be covered by a thermal barrier (1/2" drywall) because it is very flammable. A better option is Roxul ComfortBoard, which is non-flammable with R4 / inch insulation value. Just like foam board, nail or screw it to the bottom of your floor / ceiling joists. See: Roxul ComfortBoard, Model # RXCB11224, Home Depot Internet # 206789748 Store SKU # 1001748089
If you want to boost the insulation, e.g. if there is a bedroom above the garage, also fill the joist bays with Roxul Comfortbatt -- which provides R4 per inch. See: Roxul Comfortbatt Model # RXCB351525 Home Depot Internet # 202090820 Store SKU # 974419
I hope this is helpful.

Answer: 
The R value of this material is R-1 on it's own but it only works if used in conjunction with another insulation material and only in an air sealed cavity on the interior or exterior face.
This is not recommended as an insulation material by itself and certainly not in conjunction with fiberglass which has little R-value unless used in an air sealed cavity. When air can pass through fiberglass it

The R value of this material is R-1 on it's own but it only works if used in conjunction with another insulation material and only in an air sealed cavity on the interior or exterior face.
This is not recommended as an insulation material by itself and certainly not in conjunction with fiberglass which has little R-value unless used in an air sealed cavity. When air can pass through fiberglass it becomes clogged with dirt, dust, mold, animal feces, etc. which renders it completely useless as an insulation material. This stuff is often missinstalled and the R value is often over rated.

Answer: 
Zero but there is a catch. An r value is the amount of insulation, this acts more like a reflector for the temperature as opposed to an insulation wrapping. Read this for a more thorough explanation: http://www.radiantbarrierguru.com/r-value-of-radiant-barrier/

CUSTOMER REVIEWS

Rated 3.9 out of 5 by 15 reviewers.
Rated 4.0 out of 5.0 by Good product I am in the installation process now. It is well packaged and easy to install. I am only about 20% done and I can already notice a significant temperature drop. I am pleased. March 15, 2016
Rated 4.0 out of 5.0 by Seems to work... The temperature in my attic is noticeably lower +/- 20 degrees. Relatively easy to install but can be a challenge in tight spaces (at the low end of the rafters). It took about 12 hours of work to install about 1000 sqft. (200 pcs). Had a little trouble because the last 10 pcs in the box didn't have the wires (that hold the panels in place) in them. June 13, 2011
Rated 5.0 out of 5.0 by Good quality I got this product to apply an additional barrier under a sun porch that already had insulation between floor supports. Unfortunately spacing between was 12 to 14 inches so instead of placing between supports I stapled to bottom of supports. November 3, 2015
Rated 4.0 out of 5.0 by Radiant Barrier Insulation I really liked this product. I purchased more than I could use but it was a great product and easy to use. I used it for insulating walls for a renovation project I was doing. Once the panels were installed, I could tell the difference right away. It works really well. June 23, 2015
Rated 4.0 out of 5.0 by As described It installed easily enough. Like others have said, I needed to bend the bars a bit to get it to fit. My rafters aren't evenly spaced and I still had no problem. Its too early to say how much energy savings there is, if any. I've only had them installed for a few weeks. February 10, 2015
Rated 4.0 out of 5.0 by Installation tip I've read several comments about difficulty compressing the wire rods to insert the panels between the studs. My 16" on center studs were accurately spaced so I had an easier time by first bending the rods slightly into a curved shape. An inch or two helps a lot, just don't over bend them or they won't hold in place. December 3, 2014
Rated 3.0 out of 5.0 by Great material, Poor labor working quality The material itself on each sheet seems reasonable nicely of the price, BUT, each piece has different length and width (some 1-2" longer/short than standard indicated as 16"x48") and the layout alignment between the foil sheet not evenly produced. November 11, 2014
Rated 5.0 out of 5.0 by Easy installation Very easy to install by myself, no tools needed, great product, saves money on heating and cooling costs. June 17, 2014
