Re: [papercreters] Re: Insulation Value

Before the parody, let's look at something interesting.   The most valuable part of the article occurs at the end where a graph of R-value and U-value is shown, taken from another source.   I have tried to find a similar graph from another source but so far no luck.   I'm having trouble understanding this graph fully.   In the commentary, for example, it says that an insulated 2x4 wall has an R-value of 13 and a U-value of .077.   I see where the diagonal blue line intersects with the 2x4 wall line.   That point corresponds to the R-13 value on the right, but I don't see that corresponding to the U-values on the left.   The graph and commentary are attached to this email.   Anyone help?

Respectful humor is not only welcome, but encouraged. Just make sure
everyone knows what is humor and what is supposed to be fact. Be sure
to respect other people and their right to have an opinion that you
disagree with.

If you can do that, have fun.

Don't be surprised if someone writes a parody of your parody. hehehe
