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.
