In the article, are the given R values in imperial or SI units? —Preceding unsigned comment added by 134.60.112.134 (talk) 16:44, 30 October 2007 (UTC)[reply]

Imperial. An SI R-value of 40 or 60 would be ridiculously high. I've added SI U-values. EdDavies (talk) 16:30, 23 March 2011 (UTC)[reply]

This article refers to values with the notation "R_ip40", but what does this mean? This unit is hyperlinked to the article "R-value (insulation)", but that article contains no reference to or explanation of the notation "R_ip". That article does indicate the notation variant "RSI" instead of "R" to differentiate S.I. (metric) values from U.S. values. But "R" alone is ambiguous in this article unless the article states what units are used. Perhaps in this article we could give both parenthetically, e.g., "R-40 (RSI-7)"? (Conversion formulae are given in the article R-value (insulation).) In fact, with a little research I found that in Canada (probably the country most likely to need to differentiate, given its use of the metric system but also the extensive trade in building materials with the U.S.), all insulation is labelled both in customary values (designated "R") and metric values (designated "RSI"); see https://www.cmhc-schl.gc.ca/en/co/grho/grho_010.cfm. Therefore I will update this article to follow this same convention.

• In physics, superinsulation is a quantum state of zero electrical conductance (infinite resistance) - the opposite of superconductivity. Jeff Knaggs (talk) 16:06, 7 April 2008 (UTC)[reply]

Sounds like there should be a new article, superinsulation (physics), with links back and forth.Ccrrccrr (talk) 00:53, 8 April 2008 (UTC)[reply]
