Talk:Polyisocyanurate

From Wikipedia, the free encyclopedia

Thank you for including the "R-Value" in this article. As a layperson in this field, I'm still left with two important questions, however:

1. What are "facers" in this context?

2. How does "R-value" relate to "U-value" (used in the UK building code -- here, a link would be more helpful to me)?

Have put in an anchor [| On the R-value page]. I would have been happy to have seen that anchor and the section title that goes with it there. It is now.

[edit] Life Expectancy of Polyisocyanurate?

I've been able to discover information about the meathod if measuring the life expectancy (LTTR) but I have not been able to locate an answer in Years OR product degredation over # of years (5% over 20, etc.) Seanmcd51 11:15, 9 April 2007 (UTC)Sean

[edit] ISO standard

Could someone please fill in the incomplete ISO standard that is referenced? That is why the incomplete tag is on the article.Truthanado (talk) 04:43, 22 November 2007 (UTC)
