  • This article doenst seem to be neutral and reads a little like an advert. It's quotes things like this: "While offering fantastic insualtion values for a given thickness" nd is an opinion, and is not neutral. It generally reads like an advert and needs a bit of cleanup - any suggestions?. Tellyaddict 19:19, 24 January 2007 (UTC)

I reworded the article and added some references for clarification (I came here from R-value_(insulation)). Hopefully this will resolve the issues.Shawnlandden (talk) 14:52, 10 February 2008 (UTC)

What happened here?[edit]

I seem to recall that this article at one time had actual information about vacuum panelling and aerogel cores and such. Now it's just spam. I'll try and rewrite it later if I don't succumb to chronic laziness first. AeoniosHaplo 12:47, 14 March 2007 (UTC)

Although the language may not be academic, the main points seem correct. Quoting units for the R-values would be very helpful. Much of the world (including Britain) uses metric units for these purposes, and thickness needed to obtain said R-values would be helpful too. It would be good to be able to convert the old 'imperial' feet and inches, if needed, by knowing exactly the units used in the quote. (end of comment by anonymous editor)

I've just come across this article and I have to say that values such as "R-30/inch" make no sense to me as an English science teacher, even though I understand very well what an R-value is! I will edit this article to (a) add SI equivalents, as these are the internationally-understood, and (b) include the unit in which old-style/US R-values are quoted for clarity.

Change title of page?[edit]

Google gives a lot more hits for vacuum insulation panel (about 12,400) than for vacuum insulated panel (about 674). Both terms seem to refer to the same thing — for example, they are used interchangeably on this page from toolbase.org. Would anyone object if I move this page to Vacuum insulation panel? -- Sakurambo 桜ん坊 11:30, 31 July 2007 (UTC)

It should be said that the vacuum required for insulation needs to be a very high vacuum. As air pressure is lowered, there are fewer molecules to transfer heat, but the mean free path also increases. These two effects cancel out, making the heat transfer almost the same at any pressure. This relationship only breaks down at an extremely high vacuum, i.e. 10-9 torr, when there are simply not enough molecules left. --Parveson (talk) 02:30, 10 March 2010 (UTC)
