What is the R- value?
1818215
The R value varies per application. The more air space there is results in higher efficiency, so, if used in a typical installation such as stapled to rafters or across joists where there is at least several inches of air space it will have a much higher r-value than if it's mounted directly to a surface, for example, as a wrap for ductwork. The product description states: "Has R 16.8 value for crawl space applications and R 6.13 value for basement walls." Those are much higher r-values than I've seen before through testing (more than double), though may represent the max value that can be achieved if installed with a very large air space for those type of applications.

It's actually just R 1.04 (very low) - unless you put a continuous 3/4" air gap around it with spacers - which almost no one ever does. Then it goes up to R-4 or something. Here's a balanced article with the pros and cons: http://bit.ly/a4VRz0 The stuff is pretty and easy to work with and I used it one some ducts in my basement. But know its limits and certainly don't mistake it for "high performance". The stuff is only 5/16" thick and you can't magically change the laws of physics with shiny foil.

I don't know the r value, I used it on the inside of a new door to my central heater as that area is open to outside air. It works well without a lot of bulk.

The R means radial. I don't like to mix radial and bias ply tires. The tire will fit but there may be some handling issues.

Assuming that you meant Ringer equivalence number (REN), I have no idea what that means. Maybe if you could be more specific, I could answer the question.

Hello Bill, Thanks for your interest in Foam It Green. The R-value of the open cell at one inch cured thickness is R-4. What type of project are you working on? Thanks, Mark

I know the ? SAYS -R,It was my fault putting question here,I do mean as stated,+R.

I believe "R" stands for "refurbished" which means that the tool had been brought back in its new condition by the factory. The tools I bought and I reviewed were not refurbished, but I bought a DeWalt thickness planer which was refurbished and was in every respect brand new and I have been using it for years, the cutter head was perfectly aligned to the table, has offered top performance and I never had to replace anything on it except the knives, of course. Although I cannot prove it, my guess is that refurbished tools have better tolerances because the factory goes over each tool twice therefore quality control is double. You cannot see any sign of use on a refurbished tool and you cannot tell it apart from a brand new if it does not say so on the label. As a bonus, refurbished tools are cheaper as they are sold at a discount because people think of "refurbished" tools as second hand tools, which is not true. If I have the option to buy a refurbished tool at a discount price, I would go for it without a second thought.

Sorry, I'm unable to answer this question but would be interested in the response when it is provided to rgmitch. Thanks

Tx-r means it will bind with a Tactic SLT Tx or Tactic Anylink.The Anylink is an adaptor that connects to most popular Txs like the DX6i

I don't think it had a rated r value. Since it it has a combination of a thin layer of foam and air I would think it would be high. while I used it primarily on long flights to Alaska to save my butt I also used it on outings while in the bush. Butt never got cold.....if that helps

1.5" thickness = R-Value 4 2" thickness = R-Value 5 3" thickness = R-Value 6.9 ALPS Mountianeering Lightweight Sleep Pad has a R-Value of 4

I asked Vizio support the same question. The R stands for Retail. And other than the number of 3D glasses, they are the same. The A3R has eight and the other has four.

R+ has the NFC (Near Field Communication) feature where you touch the devices together and they pair. It is my understanding that R has the standard method of pairing where you hold a button until you get a flashing light and then hope for the best.

I would say that 3 of the 5 days covered by this course assume familiarity with statistics beyond, say, normal distribution parameters such as mean and standard deviation - if that is a guide. It helps if you understand what a T-test is used for, or when you would apply the Poisson distribution. You will still get value from the course without having had a lot of statistics training, but if you want to be a data scientist, you will need a very solid grounding in statistics to get the most from this course. I also suggest you review the open source R statistics package before starting this course.

Its, ok. Dont worry, that happened to me too. Over the DEL bottom, there is one with the symbol S &lt;-&gt; D, When you tap that one it gives you the option for your answer, either fraction or decimal. Hoping I helped you.

I'm sorry I can't help - there was nothing on the box or the directions stating an R value. I just know it really helped reduce the cold air leaking down from my attic stairs.

Neal: The R value depends on the application is which the product is installed. InfraStop has been tested in metal buildings and pole barns in the various installation areas. These 2 links will give you information on the R-values and necessary airspace requirements.
