Interpreting rigid foam performance board testing
I am considering using an expanded polystyrene foam board insulation to “cut and cobble,” for a project described here: https://www.greenbuildingadvisor.com/community/forum/plans-review/103733/1952-cape-cod
The product is manufactured by BASF and subsequently private labeled. I’ve posted more detail re: the use case in the above-linked thread.
Can you help me interpret the attached report from the ICC Evaluation Service? Looks to me like this is an R4-R4.5/inch product. But because I’ve never examined a report of rigid foam or any other insulation product, I’d appreciate any insight into key characteristics and whether the product seems legitimate.
