What is the "R" value equivalence of one inch of open cell foam insulation?

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 honestly don't recall the package specifying the R value. I have answered couple of questions before in re:various aspects of this product and basically I am very satisfied with it My heater sits RIGHT NEXT to my basement door - and I have an old house so that area is far from being 'warm and cozy'. I am not going to tell you whether or not we "saved money" by using this blanket - with the electricity rates going up and down and what-have-you...its not worth my time figuring out that difference. What I CAN tell you is that the difference in the temperature of the hot water was IMMEDIATELY noticed by both my wife and I in the shower and the kitchen (reasonably 2 places the hot water gets used the most). It went up a good couple of degrees, so this blanket must be doing something right hope that helps

Similar products have a conductive insulation R-value of 6.5. However, the full insulation value also includes the aluminum foil on both sides of the double bubble insulation. The aluminum foil adds a reflective insulation value. The effect of both the bubble insulation and the reflective foil is said to reduce heat loss by 40 % or so. The aluminum foil reflective portion is said to be similar to the effect the foil has on the radiant heat entering your attic space.

This foam is the "closed-cell" type. Based on my research, closed-cell is preferred over open-cell for below-grade insulation or on floor-joists in a basement or crawlspace because it is much denser than open-cell and is a very good air barrier as well as a water vapor barrier.

I think around r5 per inch. Bigger issue is that this product is open cell, rather than closed cell that is offered by vendor. The closed cell is really what you need as it is impervious to moisture. In contrast, open cell absorbs moisture and then becomes as useless as tits on a bull. Go see internet. Open cell is a waste of time and money.

I'm sorry I do not have an answer for your question. The manufacturer may be the only one that can tell if the numbers are comparable.

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.

One inch...measured from wire to wire. The actual empty space is about 7/8 inch. Too wide for any hamster, gerbil or rat unless covered in hardware mesh.

Hello Stefan,The Foam It 202 kit is designed to yield 202 sq feet of foam at 1" cured thickness. The kit itself is physically 16" x 9" x 17" high.I'd be happy to answer any additional questions you have about the Foam It 202 kit or using Foam It Green for your project. What type of project are you working on?What issues can we help you solve using Foam It Green?Thanks!Linda

It's what is called a thermal resistance rating. Read this and you'll understand it easily. :) http://en.wikipedia.org/wiki/R-value_(insulation)

I looked over the specifications available online of both items and they appear to be nearly identical (temp range, materials used). I could not find the exact same specs for both, but noticed the spec sheet for the 3M product has a disclaimer on it anyway, so I doubt you could trust a comparison 100% anyway. I do know the product is still working for me to hold the plastic part inside my clothes dryer, has not required change or reinforcement and doesn't shed parts of itself, and the adhesive is intact, after 14 months.

Settings are for the length of your boundary wire. "A" is greater than 2400 feet, "C" is for 1300-2400 linear feet and "B" is for up to 1300 feet. This is per the actual guide document, page 10. Seems like it ought to be A, B, C but it is not per the document. Per doc B, C then A. for &lt;1300, 1300-2400 then &gt;2400.

RC Ballard's response is most accurate. I meant to measure it but forgot to do so.

On the box it says open-cell poly-foam. But check their website or packaging for specifics
