Understanding NFRC site Low-E Information
Hi there, poking around on the NFRC site to x-shop windows (JW Siteline Clad vs Marvin Integrity FG/FG vs Integrity FG/Wood)
Can someone explain the Low-E information on the site? For a particular configuration it says “0.022(2) 0.149(4)”. This one the configuration I’m looking at, on the Siteline it yields U0.24 and SHGC0.18, similar code on Marvin yields about the same, U0.25.
I don’t know how to translate this into an “orderable” configuration though, and when I click the pop-up on the NFRC site nothing happens. I’m guessing the parenthetical numbers refer to number of surfaces, so 4 might mean a room-side coating?
The document “NFRC_CPC_Code_Listing” does not explain.
Also, related, when I go into the Marvin site, below, I don’t see casements under Integrity, not sure why or maybe my browser doesn’t show.
