Finish TradesCâu 471 / 700
Before installation is approved, site-built and manufactured fenestration products must generally carry which label so their energy ratings can be verified?
a.A manufacturer's paint-color sticker
b.A structural load stamp only
c.A temporary NFRC (or CEC default) label showing U-factor and SHGC
d.No label is required if the window looks new
Giải thích
Verifying compliance requires a temporary energy-performance label (NFRC certified or the applicable default values) that lists U-factor and SHGC for the inspector. A paint-color sticker or structural stamp does not report energy ratings, and windows cannot be accepted without a verifiable performance label.
