What is the R value on this sleeping insulation mat?

I'm not sure if it has a R rating, with it not being used for home insulation. But, it does keep you dry being made of closed cell foam. It also keeps the ground from sucking all the heat out of your body. Used with an appropriate rated sleeping bag for the weather you anticipate it should do great.

The manufacturer's information doesn't really say anything about R value and I doubt there is any. It must be extremely extremely small. I installed this underlayment over dricore panels. Works great...

I'm not sure. But it's a nice mat. I'm still using it for all sorts of things. Really handy.

This is unofficial, I just measured it with a ruler. It looks like it is about 2.3 mms, not counting the spikes which are approximately the same length. This has been a very good mat. We have it over a plush carpet on a 1/2" pad. It slightly indents from the chair wheels, but very little. I have tried a couple of mats, and this has been the best one.

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

I don't know a good answer to that. Once you get used to using the mat, you are not as aware of the current. I did not buy the sheets. I would assume the little "wires" in the fabric would get brittle or soft with use and washing. I think the mat would be the longer lasting. I do not use the cover with it. It doesn't bother me to be in contact with the mat. I like it, and I think the numbness and tingling in my fingers and toes/hands and feet has improved some in the months I've been sleeping with my feet/calves on it. The mat is very similar to a mouse pad in texture, thickness and flexibility. I don't know a good answer to that. Once you get used to using the mat, you are not as aware of the current.

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)

Hard to say, I ordered it for a new pillow top mattress. Sorry I can't give a better answer.

Not sure about all the R value, but I live in Las Vegas and the product has kept my garage 10 to 15 degrees cooler in the summer and so far this winter it's been the same warmer. I'm very happy with this product. 4 of my neighbors also installed this in their garages. Hope that helps

This is a very poor insulator, I believe the R-value on this stuff is a 2. I would look into other options for insulation.

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

Anna, I can't answer because we bought this for our iComfort Serta king size mattress and don't know enough about the sleep number mattress. I can tell you that we used it briefly but recently removed it as the platform part is much wider than our mattress and took up too much room, plus it was a shin banger. It's now boxed, covered and stored in the workshop.

Memory foam density is measured from 3.0 to 5.0 or higher. Does anyone know how to answer the question?

( Edit just added) I just found one on another site ( http://www.hidgrow.com/20-75-x-48-root-radiance-heat-mat-four-tray.html ) and it appears to be 105 watts. The only electrical information printed on the mat was 120V. I went to the web site and did a search for "seedling heat mat" to see if anything was there, but nothing was found, though I can click on the picture to the left and it goes to the mat - but no wattage listed in the information. My seedlings did not do well, though that could easily be something I did or did not do. I think you either need to add a rheostat or what I did was put a 24 hour timer on the plug and had the heat go on and off each hour to keep it at an average heat. That seemed to work, but again, poor results from the seeds. They were also under a 160 watt grow light and lightly covered with a piece of opaque plastic to keep the moisture at a reasonable level.
